     domestication merger agreement. (See page 134).

          2. If the domestication merger proposal is approved, to consider,
     approve and adopt the merger agreement among CoreComm, Voyager.net, Inc.
     and other parties, under which Voyager will become a wholly-owned
     subsidiary of CoreComm, and common stock of CoreComm (or its successor)
     will be issued in addition to a cash payment to the current stockholders of
     Voyager. (See page 91).

          3. If the domestication merger proposal is approved, to consider,

Dear Stockholder:


     You are cordially invited to attend the special meeting of stockholders of
Voyager.net, Inc. to be held at 9:00 a.m., local time, on September 22, 2000 at
the Second Floor Conference Center of Goodwin, Procter & Hoar LLP, located at
Exchange Place, 53 State Street, Boston, Massachusetts 02109. At the special
meeting, you will be asked to consider and approve the merger agreement under
which we will merge with a subsidiary of CoreComm Limited. You should read
carefully the merger agreement, a copy of which is attached as Annex A to the
accompanying joint proxy statement and prospectus. Upon completion of the
merger, each share of our capital stock will be converted into the right to
receive approximately 0.292 of a share of CoreComm common stock and $3.00 in
cash. The number of shares of CoreComm common stock to be received by the
holders of our capital stock may be adjusted based on CoreComm's stock price at
closing. The affirmative vote of a majority of our outstanding shares of common
stock is necessary to approve the merger agreement.


     You have the right under Delaware law to require an appraisal of your
shares and to demand the payment of fair value for your shares. We have
described these appraisal rights in detail in this joint proxy statement and
prospectus. You should read the relevant sections of the joint proxy statement
and prospectus and the statutory provisions carefully.

     Our Board of Directors unanimously adopted the merger agreement and
declared the merger agreement advisable and in the best interests of our
stockholders and unanimously recommends that our stockholders approve the merger
agreement. Among the factors considered by our Board of Directors in evaluating
the merger agreement was the opinion dated March 12, 2000 of Morgan Stanley Dean
Witter, our financial advisor, which provides that, as of such date, the merger
consideration is fair, from a financial point of view, to the holders of our
common stock. The written opinion of Morgan Stanley Dean Witter is attached as
Annex E to the accompanying joint proxy statement and prospectus and should be
read carefully and in its entirety.

     The accompanying joint proxy statement and prospectus provides you with a
summary of the merger agreement and additional information about the parties
involved. If the merger agreement is approved by the requisite holders of our
common stock, the closing of the merger will occur as soon after the special
meeting as all of the other conditions to the closing of the merger are
satisfied or waived.

     PLEASE GIVE ALL OF THIS INFORMATION YOUR CAREFUL ATTENTION. WHETHER OR NOT
YOU PLAN TO ATTEND THE SPECIAL MEETING, YOU ARE REQUESTED TO PROMPTLY COMPLETE,
SIGN AND DATE THE ENCLOSED PROXY CARD AND RETURN IT IN THE ENVELOPE PROVIDED.
THIS WILL NOT PREVENT YOU FROM VOTING YOUR SHARES IN PERSON IF YOU SUBSEQUENTLY
CHOOSE TO ATTEND THE SPECIAL MEETING.

                                             Sincerely,

                                             /s/ Christopher P. Torto

                  QUESTIONS AND ANSWERS ABOUT THE TRANSACTIONS

Q: What are the transactions?

A: THE DOMESTICATION MERGER

   The domestication merger is a transaction in which CoreComm Limited, a
   Bermuda company, will merge with and into a newly-formed, wholly-owned
   Delaware corporate subsidiary. The Delaware subsidiary will survive the
   merger. CoreComm is being domesticated to make the Voyager merger and the ATX
   merger as tax-efficient as possible.

    THE VOYAGER MERGER

   The Voyager merger is a transaction in which a newly-formed, wholly-owned
   subsidiary of post-merger CoreComm will merge with and into Voyager. Voyager
   will survive the merger as a wholly-owned subsidiary of post-merger CoreComm.
   The surviving ultimate parent company will have an authorized capitalization
   of 200 million shares of common stock and 5 million shares of preferred
   stock.

    THE ATX MERGER

   The ATX merger is a transaction in which:

    (1) ATX stockholders will receive their merger consideration;

    (2) CoreComm, once it is domesticated, will merge directly into ATX;

    (3) ATX will be renamed CoreComm Limited; and

    (4) The existing board of directors and management of CoreComm will be
        installed as the board of directors and management, respectively, of the
        newly-renamed CoreComm Limited.

   Although, in form, ATX will acquire CoreComm in the ATX merger, CoreComm
   should be viewed as the acquiring company because the resulting company will
   have the identical board of directors and senior management as CoreComm
   before the transaction, and the current shareholders of CoreComm will hold
   the majority of the outstanding stock of the resulting company. The surviving
   ultimate parent company will have an authorized capitalization of 200 million
   shares of common stock and 5 million shares of preferred stock.

    THE CAPITALIZATION INCREASE

   CoreComm shareholders are also being asked to approve an increase in the
   authorized capitalization of CoreComm to 200 million common shares and 5
   million preferred shares to facilitate acquisitions by CoreComm. The purpose
   of the capitalization increase is to facilitate future acquisitions by
   CoreComm in the event that neither the ATX merger nor the Voyager merger is
   completed.

    RELATIONSHIPS AMONG THE
    TRANSACTIONS

   The completion of each of the Voyager merger and the ATX merger is not
   conditioned on the completion of the other.

   Neither the Voyager merger nor the ATX merger will occur unless the
   domestication merger occurs first.

   The domestication merger will not occur unless at least one of the Voyager
   merger or the ATX merger is

                                        1
<PAGE>   15

   certain to occur immediately afterwards.

   The capitalization increase will occur only if neither the Voyager merger nor
   the ATX merger occurs.

Q: What will I receive in the transactions?

A: THE VOYAGER MERGER

   If you are a Voyager stockholder, each share of Voyager common stock you hold
   on the record date will be converted into the right to receive $3.00 in cash
   and 0.292 of a share of post-merger CoreComm common stock, subject to
   adjustments that are described in more detail in the summary of the Voyager
   merger beginning on page 11.


   The average trading price of CoreComm common shares, based on volume, for the
   10 trading days prior to August 21, 2000, the date of printing of this joint
   proxy statement and prospectus, was $12.06 per share. If the average trading
   price of CoreComm common shares as determined on the scheduled closing date
   of the Voyager merger in accordance with the Voyager merger agreement is less
   than $33.03, there are several things that can happen under the Voyager
   merger agreement:


     --  Voyager can notify CoreComm it wishes to terminate the agreement, in
         which case CoreComm can:

       - elect to prevent that termination by increasing the exchange ratio
         between post-merger CoreComm common stock and Voyager common stock so
         that the total value to be paid per share of Voyager common stock,
         including the $3.00 in cash, will be $15.02; or

       - allow the agreement to be terminated, in which case the Voyager merger
         would not occur; or

     --  Voyager can decline to make the termination notification, in which case
         the Voyager merger would proceed, with Voyager stockholders receiving a
         combination of cash and post-merger CoreComm common stock with a value
         equal to $3.00 plus the value of 0.3639 of a CoreComm common share. The
         amount of cash and stock will be adjusted in order to result in a
         mixture of 80% stock and 20% cash to maintain the tax-free nature of
         the Voyager merger, as described in more detail on page 13. The total
         value to be paid per share of Voyager common stock will therefore
         depend on the value of CoreComm common stock on the closing date.

   If the ATX merger is also approved by the current shareholders of CoreComm
   and completed, the shares of common stock of post-merger CoreComm will
   actually be shares of ATX. For this reason, Voyager stockholders should read
   the disclosure in this joint proxy statement and prospectus with respect to
   all three companies.

    THE ATX MERGER

   If the ATX merger is approved and completed, and you are a CoreComm
   shareholder, for each common share of CoreComm you own, you will receive one
   share of the common stock of ATX, which is post-merger CoreComm and will be
   the public, parent company.

<PAGE>   16

Q: Has someone determined that the transactions are in my best interests?

A: THE VOYAGER MERGER

   The CoreComm board of directors has determined that the Voyager merger is in
   the best interests of the shareholders of CoreComm. The CoreComm board of
   directors has unanimously approved and adopted the Voyager merger agreement.

   The Voyager board of directors has determined that the Voyager merger is in
   the best interests of the stockholders of Voyager. The Voyager board of
   directors has unanimously approved and adopted the Voyager merger agreement.

    THE ATX MERGER

   The CoreComm board of directors has determined that the ATX merger is in the
   best interests of the shareholders of CoreComm. The CoreComm board of
   directors has unanimously approved and adopted the ATX merger agreement.

Q: Do I have appraisal rights with respect to the transactions?

A: CORECOMM SHAREHOLDERS

   Under Bermuda law, if you are a CoreComm shareholder and you are not
   satisfied that you are receiving fair value in return for your shares in
   connection with the domestication merger, you can apply to a Bermuda court
   for an appraisal of the fair value of your shares. You will not have
   appraisal rights with respect to the ATX merger or the Voyager merger.

    VOYAGER STOCKHOLDERS

   Holders of Voyager common stock are entitled to appraisal rights under
   Section 262 of the General Corporation Law of the State of Delaware with
   respect to the Voyager merger.

Q: What are the tax consequences of the transactions to me?

    CORECOMM SHAREHOLDERS

   CoreComm shareholders and CoreComm will not recognize any gain or loss for
   federal income tax purposes as a result of the transactions. This will be
   true whether the Voyager merger occurs, the ATX merger occurs or both mergers
   occur. Your tax basis and your holding period in the stock you receive as a
   result of the transactions will equal your tax basis and your holding period
   in the CoreComm common shares you surrender in the exchange.

    VOYAGER STOCKHOLDERS

   Voyager will not recognize any gain or loss in the Voyager merger for federal
   income tax purposes. This will be true whether or not the ATX merger also
   occurs. If you are a Voyager stockholder, you will recognize gain equal to
   the lesser of the amount of cash that you receive or the amount of gain that
   you realize. Your tax basis in the common stock of post-merger CoreComm that
   you receive in the Voyager merger will be your tax basis in your Voyager
   stock, decreased by the amount of cash that you receive and increased by the
   amount of gain that you recognize. Your holding period in the common stock of
   post-merger CoreComm that you receive in the Voyager merger will include your
   holding period in your Voyager stock that you surrender in the Voyager
   merger.

<PAGE>   17

Q: When will the transactions be completed?

A: The stockholders of Voyager must approve the Voyager merger agreement, and
   the shareholders of CoreComm must approve all of the transactions at their
   respective special meetings. The stockholders of ATX have already approved
   the ATX merger. Some of Voyager's principal stockholders, including members
   of its management and the board of directors, who collectively hold 63.9% of
   the outstanding Voyager common stock, have entered into a voting agreement.
   Under the voting agreement, these principal Voyager stockholders have agreed
   to vote all of their shares of Voyager common stock in favor of the Voyager
   merger agreement. Accordingly, the Voyager merger is assured of approval by
   Voyager's stockholders.

   We plan to complete the transactions as soon as possible after the special
   meetings, subject to the satisfaction or waiver of the other conditions to
   the transactions. Although we cannot predict when our conditions will be
   satisfied, we hope to complete the transactions during the third quarter of
   2000.

Q: Should I send in my stock certificates now?

    CORECOMM SHAREHOLDERS

   No. If either or both of the Voyager and ATX mergers are approved and
   completed, you will receive written instructions for exchanging your CoreComm
   common shares for shares of common stock of post-merger CoreComm. Otherwise,
   you should retain your certificates, as you will continue to hold the
   CoreComm common shares you currently own.

    VOYAGER STOCKHOLDERS

   No. If the Voyager merger is completed, you will receive written instructions
   for exchanging your Voyager common shares for shares of common stock of
   post-merger CoreComm. Otherwise, you should retain your certificates, as you
   will continue to hold the Voyager common shares you currently own.

Q: What do I need to do now?

A: You should carefully read and consider the information contained in this
   joint proxy statement and prospectus, including its annexes. It contains
   important information about CoreComm, Voyager and ATX. It also contains
   important information about what the boards of directors of CoreComm and
   Voyager considered in evaluating the transactions.

   You should then complete and sign your proxy card and return it in the
   enclosed return envelope as soon as possible so that your shares will be
   represented at your company's special meeting.

Q: Can I change my vote after I have mailed my signed proxy card?

A: Yes. You can change your vote at any time before your proxy is voted at the
   applicable special meeting. You can do this in one of three ways.

   First, you can send a written notice stating that you revoke your proxy to
   CoreComm at the address listed below if you are a CoreComm shareholder, or to
   Voyager at the address listed below if you are a Voyager stockholder.

                                        4
<PAGE>   18

   Second, you can complete and submit a new proxy card, dated a later date than
   the first proxy card and send it to CoreComm or Voyager, as the case may be.
   The new proxy card will automatically replace any earlier dated proxy card
   that you returned.

   Third, you can attend the appropriate special meeting and vote in person.

   Your attendance at the special meeting will not, however, by itself revoke
   your proxy.

   You should send any notice of revocation or your completed new proxy card to

(212) 906-8485

     CoreComm, through its wholly-owned subsidiary, CoreComm, Inc., is an
innovative communications company that provides integrated telephone, Internet
and high-speed data services to business and residential customers in targeted
markets throughout the United States. CoreComm is exploiting the convergence of
telecommunications and information services through its Smart LEC(SM) network
strategy. The Smart LEC network strategy involves the ownership of telephone
switching equipment and the leasing of the local telephone lines that run
directly to homes and businesses combined with the provision of a national
network that carries Internet traffic. This configuration of locally and
nationally owned and leased facilities allows CoreComm to deliver a wide range
of communications services at a lower cost to start with in each area in which
we provide services. CoreComm's goal is to expand its facilities, geographical
reach and services to become a significant switch-based communications provider
in selected major markets across the United States. CoreComm currently offers
services to business and residential customers located principally in Ohio,
Illinois, Michigan, New York and Massachusetts. CoreComm is a competitive local
exchange carrier. A competitive local exchange carrier, sometimes referred to as
a "CLEC," is a local telephone service provider competing against the
established local telephone service provider that was the service provider in a
region prior to the opening of local telephone service to competition. As of
June 30, 2000, CoreComm had more than 100,000 business and residential local
telephone access lines in service and approximately 95,000 Internet customers.
CoreComm currently operates an Internet network that connects approximately 90
cities using approximately 50,000 miles of leased circuits. CoreComm believes
that this network will allow it to take advantage of economies of scale in the
delivery of voice, video and data. CoreComm has been developing its packaged
service offerings since 1996 and has recently expanded its products to include
high-speed services utilizing digital subscriber line (DSL) technology.

                    SUMMARY DESCRIPTION OF THE TRANSACTIONS

     CoreComm is currently traded on the Nasdaq Stock Market under the symbol
"COMM." After the transactions, post-merger CoreComm will seek to be traded on
the Nasdaq under the same symbol. Voyager is currently traded on the Nasdaq
under the symbol "VOYN."

THE MERGER BETWEEN CORECOMM AND VOYAGER


     Voyager and CoreComm executed a merger agreement on March 12, 2000, which
was amended on August 10, 2000 and is attached to this joint proxy statement and
prospectus as Annex A. The Voyager merger agreement provides that Voyager will
survive as a wholly-owned subsidiary of post-merger CoreComm. In this
transaction, each share of common stock of Voyager will be converted into the
right to receive an amount equal to $3.00 in cash and a fraction of a share of
post-merger CoreComm common stock. This merger consideration may be adjusted in
accordance with the exchange ratio described below.


   Interaction with the ATX Merger (See page 140)

     If the ATX merger is completed prior to the Voyager merger, each share of
common stock of Voyager will still be converted into the right to receive merger
consideration with the same value, subject to the same adjustments contemplated
by the Voyager merger agreement. The Voyager merger will still be structured as
a tax-free transaction under federal tax law.

   Adjustments to the Number of Shares of Stock to be Received by Voyager
Stockholders (See page 137)


     In addition to a cash payment, Voyager stockholders will receive a fraction
of a share of post-merger CoreComm common stock based on the average trading
price of CoreComm common shares prior to the closing of the Voyager merger. The
average trading price is computed as the volume weighted average trading price
of a common share of CoreComm on Nasdaq for 10 randomly selected trading days
out of the 20 consecutive trading days ending with the last trading day prior to
the closing of the Voyager merger. The volume weighted average trading price of
CoreComm common shares for the 10 trading days prior to August 21, 2000, the
date of printing of this joint proxy statement and prospectus, was $12.06 per
share.

                                       11
<PAGE>   25

     The following is a graph of the total value of the consideration that will
be received by Voyager stockholders for each share of Voyager common stock based
on the price of CoreComm common shares:

                      [AVERAGE SHARE TRADING PRICE GRAPH]

      The above graph assumes that no adjustment occurs to the upper threshold
      price of $56.97 and that Voyager does not give CoreComm notice of its
      intention to terminate the Voyager merger agreement if the average trading
      price is below $33.03 as described below. The above graph also assumes
      that the price of CoreComm common shares at the closing of the Voyager
      merger is equal to the average trading price as of that same date.

     Average trading price greater than $56.97.   If the average trading price
of CoreComm common shares is greater than $56.97, Voyager stockholders will
receive $3.00 in cash plus a fraction of a share of post-merger CoreComm common
stock worth $19.64.

     Average trading price of $41.17 to $56.97.   If the average trading price
of CoreComm common shares is at or below $56.97 and at or above $41.17, Voyager
stockholders will receive 0.292 of a share of post-merger CoreComm common stock
for each share of Voyager common stock plus $3.00 in cash. In this case, the
total value of cash and stock to be received by Voyager stockholders would be
between $15.02 and $19.64.

     Average trading price greater than $33.03 and less than $41.17.   If the
average trading price of CoreComm common shares is above $33.03 and below
$41.17, the fraction of a share of post-merger CoreComm common stock to be
received by Voyager stockholders for each share of Voyager common stock will be
adjusted, based on the average trading price. Under that adjustment formula,
Voyager stockholders will receive $12.02 worth of post-merger CoreComm common
stock for each share of Voyager common stock plus $3.00 in cash.

     Average trading price of $33.03 or less.   If the average trading price of
CoreComm common shares is below $33.03, Voyager has the right to notify CoreComm
that it wishes to terminate the Voyager merger agreement. The average trading
price will be calculated as of the end of the trading day prior to the scheduled
closing date of the
                                       12
<PAGE>   26

Voyager merger, so it will only be possible to determine whether Voyager has the
right to give the termination notification on that date.

 --  Voyager elects not to give the termination notice:

     Voyager stockholders will be entitled to receive merger consideration with
     a total value equal to 0.3639 of a share of common stock of post-merger
     CoreComm, plus $3.00 for each share of Voyager common stock.

     In order to ensure that the Voyager merger will be treated as a tax-free
     reorganization under the federal tax laws, the composition of the
     consideration will be adjusted to 80% post-merger CoreComm common stock and
     20% cash. The value of the post-merger CoreComm common stock for purposes
     of the adjustment will be based on the trading price of the CoreComm common
     shares on the date the Voyager merger closes.

     The following table shows, for various assumed trading prices of CoreComm
     common stock on the closing date:

   - the total value of the consideration to be received;

   - the composition, cash versus stock, of the consideration after the
     adjustment; and

   - the fraction of a share of post-merger CoreComm common stock to be issued
     for each share of Voyager common stock, after adjustment.

</TABLE>

 --  Voyager elects to give the termination notice:

   - CoreComm may elect to adjust the fraction of a share of post-merger
     CoreComm common stock to be issued in respect of each share of Voyager
     common stock so that the value of that fraction of a share will be $12.02.
     In that case, Voyager may not terminate the Voyager merger agreement.

     For example, if the average trading price of CoreComm common shares were
     $20.00, then Voyager could give CoreComm notice of its intention to
     terminate the Voyager merger agreement. If CoreComm elects not to accept
     the termination, it would be required to increase the fraction of a share
     of post-merger CoreComm common stock to be issued in respect of each share
     of Voyager common stock to 0.601 of a share. In this example, Voyager
     stockholders would receive 0.601 of a
                                       13
<PAGE>   27

     share of post-merger CoreComm common stock plus $3.00 in cash for each
     share of Voyager common stock, totaling $15.02 worth of consideration per
     share.

     The following table sets forth the exchange ratios between post-merger
     CoreComm common stock and Voyager common stock for some average trading
     prices of CoreComm common shares, assuming that Voyager notifies CoreComm
     of its intention to terminate the Voyager merger agreement and CoreComm
     elects to adjust the exchange ratio:

</TABLE>

   - CoreComm may also elect not to adjust the exchange ratio, in which case the
     Voyager merger agreement will terminate and the Voyager merger will not
     occur.

     To date, the Voyager board of directors has not made any decision as to
whether Voyager will notify CoreComm that it wishes to terminate the Voyager
merger agreement if the average trading price is less than $33.03. To date, the
CoreComm board of directors has not made any decision as to whether it would
elect to adjust the exchange ratio between Voyager common stock and post-merger
CoreComm common stock.

     Post-merger CoreComm will not issue fractional shares in the Voyager
merger. As a result, the total number of shares of post-merger CoreComm common
stock that each Voyager stockholder receives in the Voyager merger will be
rounded down to the nearest whole number. Each of these stockholders will also
receive a cash payment for the remaining fractional share.

   Opinion of Morgan Stanley Dean Witter (See page 107)

     Morgan Stanley Dean Witter has delivered a written opinion, dated March 12,
2000, to Voyager's board of directors. In this opinion, Morgan Stanley stated
that, as of that date, the merger consideration was fair to the holders of
shares of Voyager common stock from a financial point of view. THE FULL TEXT OF
THE OPINION OF MORGAN STANLEY, WHICH IS BASED UPON AND SUBJECT TO VARIOUS
QUALIFICATIONS AND ASSUMPTIONS, IS ATTACHED AS ANNEX E TO THIS JOINT PROXY
STATEMENT AND PROSPECTUS. STOCKHOLDERS OF VOYAGER ARE ENCOURAGED TO, AND SHOULD,
READ THE OPINION IN ITS ENTIRETY.

   Opinion of Goldman, Sachs & Co. (See page 101)

     Goldman, Sachs & Co. has delivered a written opinion, dated March 12, 2000,
to CoreComm's board of directors. In this opinion, Goldman Sachs stated that, as
of that date, the cash consideration and the stock consideration, in the
aggregate, to be exchanged under the Voyager merger agreement was fair from a
financial point of view to CoreComm. The opinion of Goldman Sachs does not
constitute a recommendation as
                                       14

to how any holder of CoreComm common shares should vote with respect to the
transaction. THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS IS ATTACHED
TO THIS JOINT PROXY STATEMENT AND PROSPECTUS AS ANNEX F. SHAREHOLDERS OF
CORECOMM ARE ENCOURAGED TO, AND SHOULD, READ THE OPINION IN ITS ENTIRETY.

   Material Federal Income Tax Consequences (See page 264)

     The cash that Voyager stockholders are entitled to receive may be reduced,
and the stock consideration increased, if either of the tax opinions to be
delivered by counsel to CoreComm or Voyager cannot be delivered because less
than 80% of the value of the merger consideration would be in the form of shares
of common stock of post-merger CoreComm. TAX MATTERS ARE COMPLICATED AND THE TAX
CONSEQUENCES OF THE VOYAGER MERGER TO YOU WILL DEPEND ON THE FACTS OF YOUR
PARTICULAR SITUATION. WE URGE YOU TO CONSULT YOUR TAX ADVISOR FOR A FULL
UNDERSTANDING OF THE TAX CONSEQUENCES OF THE VOYAGER MERGER TO YOU.

   Interests of Voyager Directors and Management in the Voyager Merger (See page
114)

     Some of Voyager's officers and directors have interests in the Voyager
merger that are different from, or in addition to, those of Voyager stockholders
generally because of the vesting of their options upon the completion of the
Voyager merger. In addition, in connection with the execution of the Voyager
merger agreement, directors and officers of Voyager entered into agreements with
CoreComm under which promissory notes previously issued in Voyager's favor by
these directors and officers will remain outstanding following the Voyager
merger but subject to revised terms. Also, the principal stockholders of Voyager
have agreed to enter into a registration rights agreement with post-merger
CoreComm at the closing of the Voyager merger.

   Conditions to the Voyager Merger (See page 152)

     CoreComm and Voyager will not complete the Voyager merger unless a number
of conditions are satisfied or waived, including adoption of the Voyager merger
agreement by the Voyager stockholders and the approval and adoption by CoreComm
shareholders of the Voyager merger agreement.


   Regulatory Approvals (See page 148)


     CoreComm and Voyager have satisfied the requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 with respect to the Voyager
merger.

     Voyager holds licenses and authorizations to provide intrastate
telecommunications services in six states. The transfer of control of these
licenses and authorizations to post-merger CoreComm must be approved by state
public utilities commissions in several of these states. Other state commissions
require notification that the licenses and authorizations are being transferred.
Voyager and CoreComm are in the process of obtaining the necessary approvals and
making the required notifications.

   Termination of the Voyager Merger Agreement (See page 153)

     CoreComm and Voyager can mutually agree to terminate the Voyager merger
agreement at any time before completing the Voyager merger. Both CoreComm and
Voyager can terminate the Voyager merger agreement if:

     - a final decree or injunction by a court or government entity prevents the
       completion of the Voyager merger; or

     - the other party breaches any of its representations, warranties,
       covenants or agreements and the breach causes specified conditions to
       fail to be satisfied.

     CoreComm can terminate the Voyager merger agreement under additional
circumstances, including if:

     - the Voyager stockholders do not approve the Voyager merger agreement;

     - the Voyager board of directors withdraws or adversely modifies its
       recommendation to its stockholders for adoption of the Voyager merger; or

     - the Voyager board of directors enters into a definitive agreement with
       respect to an alternative transaction that the Voyager board of directors
       has determined in good faith, after consultation with its advisors, would
       result in a transaction more favorable to Voyager stockholders from a
       financial point of view.

     Voyager can terminate the Voyager merger agreement under additional
circumstances, including if:

     - the average trading price of a share of CoreComm common stock during a
       specified period ending shortly before the completion of the Voyager
       merger is less than $33.03, subject to CoreComm not electing to adjust
       the exchange ratio;

     - the Voyager board of directors provides written notification to CoreComm
       of its election to terminate the Voyager merger agreement in order to
       recommend or approve a superior proposal and, after accounting for any
       subsequent modification of the Voyager merger agreement proposed by
       CoreComm, the Voyager board of directors determines that the alternative
       transaction continues to be a superior proposal; or

     - the Voyager merger is not completed on or before October 31, 2000 and
       Voyager is not in material breach of its obligations.


   Termination Fee (See page 154)


     Voyager will pay CoreComm a termination fee of $19.0 million if:

     - Voyager terminates the Voyager merger agreement in order to recommend or
       approve a superior proposal; or
                                       16
<PAGE>   30

     - CoreComm terminates the Voyager merger agreement because the Voyager
       board of directors:

         - withdraws its recommendation of the Voyager merger agreement;

         - approves an alternative acquisition proposal;

         - enters into a definitive agreement with respect to a superior
     proposal; or

         - announces publicly that it will take any of the foregoing actions.

THE MERGER BETWEEN CORECOMM AND ATX

     On March 9, 2000, CoreComm, ATX and the stockholders of ATX entered into a
merger agreement, which was amended on April 10, 2000, July 10, 2000 and July
31, 2000, which is attached to this joint proxy statement and prospectus as
Annex B. Under the ATX merger agreement, CoreComm, once it is domesticated, will
merge directly into ATX. ATX will become the new parent company in which
CoreComm shareholders will own shares and will have the identical senior
management and board of directors as CoreComm. Current CoreComm shareholders
will hold a majority of the outstanding common stock of post-merger CoreComm
after the ATX merger. The ATX merger agreement provides for a transaction that
will have these principal steps:

     - CoreComm will reorganize as a Delaware corporation through the
       domestication merger.

     - ATX will undergo a recapitalization as described below.

     - The newly-domesticated CoreComm will merge with and into ATX. ATX will be
       renamed CoreComm Limited, and all of the outstanding common shares of
       CoreComm will be exchanged for common stock of that resulting company,
       which will survive as post-merger CoreComm.


   Interaction with the Voyager Merger (See page 164)


     If the Voyager merger is completed prior to the ATX merger, stockholders of
Voyager will be treated as shareholders of CoreComm under the ATX merger
agreement based on the number of shares of post-merger CoreComm common stock
that they would receive in the Voyager merger.


   Stock to be Received by CoreComm Shareholders (See page 164)



     The current shareholders of CoreComm will receive one share of post-merger
CoreComm common stock for each share of CoreComm common stock they hold at the
time of the ATX merger.

   The Consideration to be Paid to ATX's Stockholders (See page 160)


     All shares of ATX common stock are currently held by four stockholders. In
the ATX recapitalization, shares of the ATX common stock that they currently
hold will be exchanged for:

     - approximately 12.4 million shares of post-merger CoreComm common stock,
       subject to adjustment as described below;

     - 250,000 shares of post-merger CoreComm convertible preferred stock, face
       amount $250.0 million, convertible into between approximately 5.64
       million and 7.78 million shares of post-merger CoreComm common stock; and

     - $150.0 million in cash, of which up to $110 million may be paid in the
       form of three-year senior notes, at CoreComm's option, plus up to $9
       million of additional three-year senior notes, if any three-year senior
       notes are actually issued.

     The number of shares of post-merger CoreComm common stock to be issued to
ATX's stockholders is subject to a "collar" provision. If the volume
weighted-average trading price of the common shares of CoreComm during the ten
trading days prior to the closing date of the ATX merger is greater than a
specified threshold stock price, then the number of shares of post-merger
CoreComm common stock to be issued to the existing ATX stockholders will be
adjusted. The threshold stock price equals $46.3772 prior to July 15, 2000 and
will increase gradually after that, in the event that CoreComm completes
specified types of transactions that have the effect of delaying the
finalization of this joint proxy statement and prospectus. Under this
adjustment, the aggregate value of the post-merger CoreComm common stock
received by the existing ATX stockholders, based on that ten day average trading
price of CoreComm common shares, will be increased to equal the original value
($500.0 million) multiplied by a fraction, the numerator of which is the
threshold stock price and the denominator of which is $40.328.

     Beginning in mid-July, CoreComm, ATX and the stockholders of ATX began
discussions to explore the possibility of restructuring the terms of the ATX
merger to increase the portion of the $150 million of cash consideration that
could be paid, at CoreComm's option, in the form of notes, and to make other
changes to the terms of the consideration to be received by the ATX
stockholders. Negotiations continued through July 31, 2000, when the parties
agreed to amend the original merger agreement. The CoreComm board of directors
approved all of the amendments.

   Opinion of Financial Advisor (See page 126)

     Goldman, Sachs & Co. has delivered its written opinion, dated August 10,
2000 to the board of directors of CoreComm. In this opinion, Goldman Sachs
stated that, as of that date, the stock consideration and the cash
consideration, in the aggregate, to be paid by CoreComm under the ATX merger
agreement was fair from a financial point of view to CoreComm. The opinion of
Goldman Sachs does not constitute a recommendation as
                                       18
<PAGE>   32

to how any holder of CoreComm common shares should vote with respect to the
transaction. THE FULL TEXT OF THE AUGUST 10, 2000 WRITTEN OPINION OF GOLDMAN
SACHS IS ATTACHED TO THIS JOINT PROXY STATEMENT AND PROSPECTUS AS ANNEX G.
SHAREHOLDERS OF CORECOMM ARE ENCOURAGED TO, AND SHOULD, READ THE OPINION IN ITS
ENTIRETY. GOLDMAN SACHS DELIVERED A SIMILAR OPINION DATED MARCH 9, 2000 WITH
RESPECT TO THE CONSIDERATION TO BE PAID UNDER THE ATX MERGER AGREEMENT AS OF
THAT DATE.

   Interests of CoreComm Directors and Management in the ATX Merger (See page
133)

     Some of CoreComm's officers and directors have interests in the ATX merger
that are different from, or in addition to, those of CoreComm shareholders
generally. In connection with the ATX merger, the officers of CoreComm will
become the officers of post-merger CoreComm. All of the current directors of
CoreComm will become the directors of post-merger CoreComm. All outstanding
options under CoreComm's 1998 and 1999 stock option plans will vest and become
exercisable upon completion of the ATX merger. However, CoreComm has obtained
waivers from its officers and directors and is seeking waivers from its other
employees to forego the acceleration of the vesting of their outstanding options
granted under these plans that would otherwise vest and become exercisable upon
completion of the ATX merger.

   Conditions to the ATX Merger (See page 173)

     The completion of the ATX merger will not occur unless a number of
conditions are satisfied, including the adoption of the ATX merger agreement by
the holders of at least a majority of the common shares of CoreComm outstanding
on the record date for the CoreComm special meeting and there not having
occurred a material adverse change to CoreComm or ATX.


   Regulatory Approvals (See page 173)


     CoreComm and ATX have satisfied the requirements of the Hart-Scott-Rodino
Act with respect to the ATX merger.

     ATX holds licenses and authorizations issued by various state public
utilities commissions. The transfer of control of these licenses and
authorizations to CoreComm must be approved by some of these state commissions.
Other state commissions require notification that the licenses and
authorizations are being transferred. Notification or approval of CoreComm's
domestication merger and the restructuring of CoreComm in connection with the
ATX merger is also required in some of the states where CoreComm's subsidiaries
are authorized to provide service. In addition, CoreComm and ATX will seek
approval for the transfer of FCC authorizations held by ATX. ATX and CoreComm
are in the process of obtaining the necessary approvals and making the required
notifications.

<PAGE>   33


   ATX Stockholder Covenants and Restrictions on Transfer (See page 175)


     The ATX merger has already been approved by the stockholders of ATX. The
current ATX stockholders have agreed not to transfer any of their existing
shares of ATX common stock prior to the closing of the transactions, other than
as contemplated in the ATX merger agreement.

   Termination of the ATX Merger Agreement (See page 175)

     CoreComm and ATX can jointly agree to terminate the ATX merger agreement at
any time before completing the ATX merger. Either CoreComm or ATX can terminate
the ATX merger agreement if the other party breaches any of its representations,
warranties, covenants or agreements and the breach causes specified conditions
to fail to be satisfied. ATX can terminate the ATX merger agreement if the ATX
merger is not completed by October 31, 2000 and any ATX closing condition has
not been satisfied or waived. In addition, CoreComm can terminate the ATX merger
agreement if any CoreComm closing condition has not been satisfied or waived and
the ATX merger is not completed by the later of:

     - October 31, 2000; and

     - 120 days after the date CoreComm announces a transaction that may trigger
       an adjustment in the threshold stock price.

RECENT DEVELOPMENT

     On August 14, 2000, CoreComm announced that it had received a total of $310
million of committed financing.

     Of that financing, $150 million is in the form of a commitment for a fully
underwritten eight-year senior secured credit facility by Chase Manhattan Bank,
$100 million of which will be in the form of a term loan facility and $50
million of which will be in the form of a revolving credit facility. The other
terms of the credit facility, including customary affirmative, negative and
financial covenants, will be established once final documentation is produced.


     A further $110 million is in the form of the senior notes that may be
issued to the current ATX stockholders. The terms of the senior notes are
described in more detail on page 162 of this joint proxy statement and
prospectus.


     The remaining $50 million is in the form of a new series of convertible
preferred stock that will pay dividends at a rate of 8.5% per year and will be
mandatorily redeemable 10 years after issuance. Dividends may be paid in the
form of common stock or additional shares of convertible preferred stock. The
conversion price will initially be $16.50 per share. The holders of the
convertible preferred stock will have registration rights. Other terms will be
established once final documentation is produced.

     The completion of the $150 million credit facility and the sale of the $50
million convertible preferred stock is subject to CoreComm obtaining
approximately $50 million of additional financing that would be subordinated to
the $150 million credit facility, the
                                       20
<PAGE>   34

completion of definitive documentation and other customary closing conditions.

                ABOUT THIS JOINT PROXY STATEMENT AND PROSPECTUS

     This joint proxy statement and prospectus will be part of a registration
statement that will be filed by the surviving company in the ATX merger, which
will be named CoreComm Limited, to register the issuance of its common stock to
the current shareholders of CoreComm and the current stockholders of Voyager.
Those shares will be held by public stockholders only if the ATX merger is
approved and completed.

     This joint proxy statement and prospectus will also be a part of a
registration statement that will be filed by the Delaware corporation into which
CoreComm will merge in the domestication merger to register the issuance of its
common stock to the current shareholders of CoreComm and the current
stockholders of Voyager. That corporation, CoreComm Merger Sub, Inc., has not
commenced operations and has only nominal assets and liabilities. Those shares
will be held by public stockholders only if the Voyager merger is approved and
completed but the ATX merger is not.

     Because the completion of each of the Voyager merger and the ATX merger is
not conditioned on the completion of the other, until the required shareholder
votes occur and the mergers that are approved are completed, it is not possible
to know which company will survive the mergers as the ultimate parent company.
Therefore, registration statements for the surviving company resulting from
completion of the ATX merger and the surviving company resulting from the
completion of only the Voyager merger and not the ATX merger will be filed.
However, the stock of only one company -- the ultimate parent company, depending
on which mergers occur -- will be held and publicly traded.

                 SUMMARY HISTORICAL FINANCIAL DATA OF CORECOMM

     The following summary financial data of CoreComm and its predecessor, OCOM
Corporation Telecoms Division, has been derived from, and should be read in
conjunction with, the historical consolidated financial statements and related
notes incorporated by reference in this joint proxy statement and prospectus.
The summary historical financial data relates to OCOM as it was operated prior
to its acquisition by CoreComm.

     Interim data for the six months ended June 30, 2000 and 1999 are unaudited
but include, in the opinion of CoreComm management, all adjustments consisting
only of normal recurring adjustments necessary for a fair presentation of that
data. Results for the six months ended June 30, 2000 are not necessarily
indicative of the results that may be expected for any other interim period or
the year as a whole.

     In 2000, the Company recorded a non-cash compensation expense of
approximately $32.2 million in accordance with APB opinion No. 25, "Accounting
for Stock Issued to Employees."

     In 1999, CoreComm acquired 100% of the stock of MegsINet Inc. and some of
the assets of USN Communications, Inc. In addition, CoreComm issued $175.0
million in aggregate principal amount of 6.00% convertible subordinated notes
due 2006.

     OCOM incurred one-time costs of $2,294,000 in 1995 in connection with the
expansion of its cellular long distance resale business into certain AT&T
Wireless markets.

(1) After giving retroactive effect to the 3-for-2 stock split by way of stock
    dividend paid in September 1999 and the 3-for-2 stock split by way of stock
    dividend paid in February 2000. The weighted average number of common shares
    prior to September 1998 are equivalent to the historical weighted average
    shares of CoreComm's former parent company, Cellular Communications of
    Puerto Rico, Inc. (since CCPR shareholders received one CoreComm common
    share for each CCPR share owned). CoreComm has never declared or paid any
    cash dividends.

                  SUMMARY HISTORICAL FINANCIAL DATA OF VOYAGER

     The following tables set forth summary consolidated historical financial
information and other data for Voyager. The summary consolidated results of
operations and the selected historical consolidated balance sheets have been
derived from the consolidated financial statements of Voyager. For all periods
presented, the related financial information has been presented using consistent
methods of accounting.

     You should read the following summary historical consolidated financial
statements and other data in conjunction with Voyager's consolidated financial
statements and related notes and the section of this joint proxy statement and
prospectus entitled "Management's Discussion and Analysis of Voyager Financial
Condition and Results of Operations."

     The selected consolidated financial and other data includes a presentation
of EBITDA. As used in this filing, EBITDA represents earnings before interest,
taxes, depreciation, amortization and non-recurring, non-cash compensation
charges. EBITDA is provided because it is a measure commonly used by investors
to analyze and compare companies on the basis of operating performance. EBITDA
is not a measurement of financial performance under generally accepted
accounting principles, and should not be construed as a substitute for operating
income, net income or cash flows from operating activities for purposes of
analyzing our operating performance, financial position and cash flows. EBITDA,
as calculated by Voyager is not necessarily comparable with similarly titled
measures for other companies.

                   SUMMARY PRO FORMA PER SHARE AND OTHER DATA

     The following table presents the historical net loss and book value per
share of CoreComm, ATX and Voyager and on a pro forma basis for CoreComm and an
equivalent pro forma basis for Voyager. Pro forma data for CoreComm was derived
by combining the historical financial statements of CoreComm, ATX and Voyager,
giving effect to: (1) the ATX merger only, (2) the Voyager merger only and (3)
both the ATX merger and Voyager merger, as well as the MegsINet and USN
acquisitions, using the purchase method of accounting.

     ATX did not have any authorized common stock or similar equity units prior
to February 2000. Therefore, for purposes of this pro forma data, an estimate of
12,398,000 "historical shares" was derived based upon the number of CoreComm
common shares offered as consideration in the ATX merger. Equivalent pro forma
information for Voyager is presented on an equivalent share basis, which
reflects CoreComm's pro forma amounts multiplied by the fraction of a common
share of CoreComm (0.4142, subject to adjustment) to be exchanged for each
Voyager share. See the footnotes to "Unaudited Pro Forma Financial Data" for
assumptions used.

     Pro forma income statement-related per share amounts have been prepared as
if the proposed transactions had occurred at the beginning of the earliest
period presented. Pro forma book value per share amounts give effect to the
proposed transactions as though they had been consummated on the date indicated.

     The information set forth below should be read in conjunction with the
"Unaudited Pro Forma Financial Data" on page 219 of this joint proxy statement
and prospectus and the respective audited consolidated financial statements and
notes of CoreComm, which are incorporated by reference in this joint proxy
statement and prospectus, and ATX and Voyager, which are attached as F-pages to
this joint proxy statement and prospectus.

     The CoreComm historical net loss per share for 1998 is for the period from
April 1, 1998, the date operations commenced, to December 31, 1998. The CoreComm
historical data for 1997 is for OCOM, the predecessor company.

                                  RISK FACTORS

     You should consider carefully all of the information set forth in this
joint proxy statement and prospectus and incorporated by reference in this
document. Please refer to "Where You Can Find More Information." You should
particularly evaluate the following risks before deciding to vote on the various
proposals described in this joint proxy statement and prospectus. If both the
Voyager merger and the ATX merger occur, CoreComm shareholders and Voyager
stockholders will be receiving shares of the common stock of post-merger
CoreComm. In that circumstance, post-merger CoreComm will combine the businesses
of CoreComm, Voyager and ATX. Accordingly, CoreComm shareholders and Voyager
stockholders should consider carefully the risks and uncertainties associated
with the business and operations of all three companies. Some statements in this
joint proxy statement and prospectus, including some of the following risk
factors, constitute forward-looking statements. Please refer to the section of
this joint proxy statement and prospectus entitled "Special Note Regarding
Forward-Looking Statements."

RISK FACTORS RELATING TO POST-MERGER CORECOMM'S BUSINESS:

     These risk factors relate to CoreComm's current businesses, Voyager's
current businesses and ATX's current businesses. Accordingly, we have referred
to the public, parent company that would result from either merger occurring
alone or both mergers occurring together as "post-merger CoreComm" in these risk
factors. If only the Voyager merger or only the ATX merger occurs, these risk
factors would still apply except for risk factors that apply only to a company
that is not acquired by CoreComm. References to "we" or "us" refer to CoreComm,
Voyager and ATX.

   WE EXPECT POST-MERGER CORECOMM TO INCUR NET LOSSES AND NEGATIVE CASH FLOW
FROM OPERATIONS.

     On a pro forma basis giving effect to the Voyager merger and the ATX
merger, post-merger CoreComm would have had net losses available to common
stockholders for the six months ended June 30, 2000 and for the fiscal year
ended December 31, 1999 of approximately $217.7 million and $337.2 million,
respectively. On a pro forma basis giving effect to only the Voyager merger,
those net losses would have been approximately $144.4 million and $208.6
million, respectively. On a pro forma basis giving effect to only the ATX
merger, those net losses would have been approximately $194.2 million and $267.0
million, respectively.

     Capital and operating expenditures for post-merger CoreComm's Smart LEC
network and its other businesses will result in negative cash flow, which we
expect will continue at least until post-merger CoreComm establishes an adequate
customer base for its services. Voyager by itself incurred net losses of
approximately $0.8 million, $7.3 million, $16.1 million and $13.8 million in the
fiscal years ended December 31, 1997, 1998 and 1999 and the six months ended
June 30, 2000, respectively.

     We also expect post-merger CoreComm to incur substantial future operating
losses, and we cannot assure you that it will achieve or sustain profitability
in the future. If post-merger CoreComm fails to become profitable, it could
adversely affect its ability to

                                       30
<PAGE>   44

sustain its operations and to obtain additional required funds. In addition,
failing to become profitable would adversely affect its ability to make the
required payments on its indebtedness.

     For more information, please refer to the section of this joint proxy
statement and prospectus entitled "Unaudited Pro Forma Financial Data."

  TO DEVELOP ITS BUSINESS, FUND ITS CAPITAL COMMITMENTS AND SERVICE ITS
  INDEBTEDNESS AND OTHER OBLIGATIONS, POST-MERGER CORECOMM WILL REQUIRE A
  SIGNIFICANT AMOUNT OF CASH.

     The continued development, construction and operation of post-merger
CoreComm's business will require substantial capital.

     Post-merger CoreComm's Smart LEC strategy will require large amounts of
capital to build and maintain the network, including building through
acquisitions. In addition, post-merger CoreComm's businesses that resell
services provided by larger, facilities-based companies will require additional
money to acquire new customers and to finance the support of these new
customers. Post-merger CoreComm's businesses will also require additional
billing, customer service and other back-office expenditures.

     In addition, post-merger CoreComm will require significant amounts of
capital to finance its other capital expenditures, meet its operating costs and
meet all of its debt service and other obligations as they become due, including
a potential contingent cash payment in July 2000 in connection with CoreComm's
prior acquisition of some of the assets of USN. This contingent payment is
payable only if the USN assets meet or exceed operating performance thresholds.

     We intend post-merger CoreComm to fund these requirements from cash, cash
equivalents and marketable securities on hand, future issuances of debt and
equity (both public and private) and funds internally generated by operations.
We cannot give you any assurance that sufficient resources will be available to
meet post-merger CoreComm's expected requirements and obligations.

     As a result, we cannot assure you that post-merger CoreComm will be able to
repay Voyager's and CoreComm's present or its own future indebtedness.
Accordingly, post-merger CoreComm may be required to consider a number of
measures, including:

     - limiting or eliminating business projects, including entry into
       additional markets;

     - refinancing all or a portion of its debt;

     - seeking modifications of the terms of its debt;

     - seeking additional debt financing, which would be subject to obtaining
       necessary lender consents;

     - seeking additional equity financing; or

     - a combination of these measures.

     We cannot assure you that any of the possible measures can be accomplished,
or can be accomplished in sufficient time to make timely payments with respect
to its

                                       31
<PAGE>   45

indebtedness. In addition, we cannot assure you that any measures can be
accomplished on terms which will be favorable to post-merger CoreComm and its
subsidiaries.

  POST-MERGER CORECOMM WILL FACE HEAVY COMPETITION IN THE TELECOMMUNICATIONS
  INDUSTRY FOR ALL OF THE SERVICES IT WILL PROVIDE AT ITS INCEPTION AND THOSE IT
  INTENDS TO PROVIDE IN THE FUTURE.

     General.   Some of our present competitors and potential future competitors
may have greater financial, technical, marketing, personnel and other resources
than post-merger CoreComm. The competitive environment could have a variety of
adverse effects on post-merger CoreComm. For example, it could:

     - require price reductions in the fees for services and require increased
       spending on marketing, network capacity and product development;

     - negatively impact post-merger CoreComm's ability to generate greater
       revenues and profits from sources other than post-merger CoreComm's core
       local and long distance telephone, cellular and Internet service
       businesses;

     - limit post-merger CoreComm's ability to develop new products and
       services;

     - limit post-merger CoreComm's ability to continue to grow its subscriber
       base; and

     - result in attrition in post-merger CoreComm's subscriber base.

     Any of the above events could have an adverse impact on revenues or result
in an increase in costs as a percentage of revenues, either of which could have
a material adverse effect on post-merger CoreComm's business, financial
condition and operating results.

     Local Telephone Business.   In each of post-merger CoreComm's markets, it
will face competition from larger, better capitalized incumbent local exchange
carriers, including Ameritech and Bell Atlantic, as well as other providers of
telecommunications services, such as GTE, other competitive local exchange
carriers and cable television companies. An incumbent local exchange carrier is
an established local telephone service provider that was the monopoly service
provider in a region prior to the opening of local telephone service to
competition. Post-merger CoreComm also will face competition or prospective
competition from other telecommunications companies. For example, AT&T, MCI
WorldCom and Sprint, among other carriers, have begun to offer local
telecommunications services in major U.S. markets using their own facilities or
by resale of the incumbent local exchange carriers' or other providers'
services. In fact, some of post-merger CoreComm's potential competitors,
including AT&T, MCI WorldCom and Sprint, have entered into interconnection
agreements with Ameritech to provide local exchange service in states in which
post-merger CoreComm will operate.

     In addition to these long distance carriers, entities that currently offer
or are potentially capable of offering switched telecommunications services
include:

     - other competitive local exchange carriers;

     - other long distance carriers;

                                       32
<PAGE>   46

     - wireless telephone system operators;

     - large customers who build private networks;

     - cable television companies; and

     - other utilities.

     Competition in the competitive local exchange carrier business will
continue to intensify in the future due to the increase in the size, resources
and number of market participants. Many have committed substantial resources to
building their networks or to purchasing competitive local exchange carriers or
inter-exchange carriers with complementary facilities. By building or purchasing
a network or entering into interconnection agreements or resale agreements with
incumbent local exchange carriers, including regional Bell operating companies,
which are incumbent local exchange carriers created by AT&T's divestiture of its
local exchange business, a provider can offer single source local and long
distance services similar to those post-merger CoreComm will offer. These
additional alternatives may provide these competitors with greater flexibility
and a lower cost structure than ours. Some of these competitive local exchange
carriers and other providers of local exchange service are acquiring or being
acquired by inter-exchange carriers. Any of these combined entities may have
resources far greater than those of post-merger CoreComm. These combined
entities may provide a bundled package of telecommunications products, including
local and long distance telephone, that is in direct competition with the
products offered or planned to be offered by post-merger CoreComm.

     Internet Services.   The Internet services market is extremely competitive.
Post-merger CoreComm will compete directly or indirectly with the following
categories of companies:

     - established online services, such as America Online, the Microsoft
       Network and Prodigy;

     - local, regional and national Internet service providers, which are
       vendors that provide subscribers access to the Internet, such as
       EarthLink Network, Inc. and Internet America;

     - national telecommunications companies, such as AT&T and GTE;

     - regional Bell operating companies, such as Ameritech and Bell Atlantic;
       and

     - online cable services, such as Excite@Home and Roadrunner.

     This competition will likely increase as large diversified
telecommunications and media companies acquire Internet service providers and as
Internet service providers consolidate into larger, more competitive companies.
Diversified competitors may bundle other services and products with Internet
connectivity services, potentially placing post-merger CoreComm at a significant
competitive disadvantage. As a result, post-merger CoreComm's businesses may
suffer.

     Post-merger CoreComm's DSL service offering will also face competition from
traditional telephone companies, cable modem service providers, competitive
telecommu-
                                       33
<PAGE>   47

nications companies, traditional and new national long distance carriers, other
Internet service providers, on-line service providers and wireless and satellite
service providers. Many of these competitors have longer operating histories,
greater name recognition and better strategic relationships than post-merger
CoreComm will have.

     Local Multipoint Distribution Service.   Depending on the services
ultimately offered through post-merger CoreComm's local multipoint distribution
service business, it could face the same competition as post-merger CoreComm's
competitive local exchange carrier business. Local multipoint distribution
service is a telecommunications system that provides wireless multi-channel
video services and wireless data services. To the extent that local multipoint
distribution service is used to deliver pay television, post-merger CoreComm's
planned local multipoint distribution service business will compete with
franchised cable television systems and may face competition from several other
types of multichannel video service providers, such as:

     - multichannel multipoint distribution systems;

     - satellite master antenna television systems;

     - direct broadcast satellite, and other television receive-only satellite
       dishes;

     - video service from telephone companies; and

     - open video system operators.

     Multichannel video service providers face competition from other sources of
entertainment, such as movie theaters and computer on-line (including Internet)
services. Further, premium movie services offered by multichannel video service
providers have encountered significant competition from the home video industry.
In areas in which several off-air television broadcasts can be received without
the benefit of terrestrial distribution systems, multichannel video service
providers have experienced competition from these broadcasters. Internet service
providers also serve as a source of competition to multichannel video service
providers.

     The Telecommunications Act of 1996 relaxed the regulatory barriers to entry
by incumbent local exchange carriers for the provision of video programming in
their local telephone service areas, and substantially reduced current and
future regulatory burdens on franchised cable television systems. This may
result in significant additional competition to local multipoint distribution
service operators from local telephone companies and franchised cable television
systems.

     Other Businesses.   In addition to post-merger CoreComm's competitive local
exchange carrier, Internet and local multipoint distribution service businesses,
post-merger CoreComm's other businesses will face strong competition as well.
These competitive businesses include long distance service, cellular service and
paging service. Post-merger CoreComm's long distance service will face
competition from long distance carriers, including facilities-based carriers
such as AT&T, MCI WorldCom and Sprint and resellers of long distance service.
Post-merger CoreComm's cellular service will face competition from other
cellular carriers, such as VodaFone AirTouch and AT&T, and from personal
communications service carriers, such as Sprint PCS. Post-merger

                                       34
<PAGE>   48

CoreComm's paging services will be similarly exposed to competition from other
providers of paging services operating in the same local markets, regionally or
nationally.

  THE TELECOMMUNICATIONS INDUSTRY IS HIGHLY REGULATED BY THE FEDERAL GOVERNMENT
  AND BY STATE GOVERNMENTS, AND POTENTIAL REGULATORY CHANGES COULD HAVE AN
  ADVERSE EFFECT ON POST-MERGER CORECOMM'S OPERATIONS.

     Local Telephone and Other Businesses.   Post-merger CoreComm's telephone
businesses are subject to extensive regulation by the FCC and by the public
utility commissions of various states. Changes in statutes, regulations or
judicial interpretations could have material adverse effects on its operations.
The FCC is currently considering various aspects of local exchange competition,
including pricing flexibility for incumbent local exchange carriers with regard
to interstate access charges assessed on inter-exchange carriers, universal
service payments, eligibility to provide universal service, access to
telecommunications services by persons with disabilities, telephone number
portability, rates for resold services and separate network elements,
availability of various incumbent local exchange carrier network elements,
access to advanced services (e.g., DSL) provided by incumbent local exchange
carriers, collocation in incumbent local exchange carrier central offices, and
reciprocal compensation for calls to Internet service providers. A number of
these issues are the subject of court cases. An unfavorable decision on any one
of these items could decrease post-merger CoreComm's revenues, increase its
costs, and make it more difficult to attract and retain customers. It is
impossible to determine at this time how the FCC will rule on any of these
issues.

     Internet Services.   Post-merger CoreComm will provide Internet services
through data transmissions over public telephone lines and their networks. These
transmissions are subject to the regulation of the FCC and state public utility
commissions described above. As an Internet service provider, post-merger
CoreComm will not be subject to direct regulation by the FCC or any other
governmental agency, other than regulations applicable to businesses generally.
However, post-merger CoreComm could become subject to FCC or other regulatory
agency regulation, especially as Internet services and telecommunications
services converge. Changes in the regulatory environment could decrease
post-merger CoreComm's revenues, increase its costs and affect its service
offerings.

     There have been various regulations and court cases relating to liability
of Internet service providers and other online service providers for information
carried on or through their services or equipment, including in the areas of
copyright, indecency, obscenity, defamation and fraud. The United States Supreme
Court declared the Communications Decency Act of 1996 to be unconstitutional as
it applies to the transmission of indecent on-line communications to minors, and
a lower court declared the 1998 Federal Child Online Protection Act to be
unconstitutional. Other federal and state statutes continue to prohibit the
online distribution of obscene materials. The law in this area is unsettled and
there may be new legislation and court decisions that expose Internet service
providers to liabilities or affect their services.

                                       35
<PAGE>   49

     Additional laws and regulations may be adopted with respect to the
Internet, covering issues such as Universal Service Fund support payments,
content, user privacy, pricing, libel, obscene material, indecency, taxation,
gambling, intellectual property protection and infringement and technology
export and other controls. Other federal Internet-related legislation has been
introduced which may limit commerce and discourse on the Internet. The FCC has
ruled that Internet service providers are enhanced service providers, calls to
Internet service providers are jurisdictionally interstate, and that Internet
service providers should not pay access charges applicable to telecommunications
carriers. An appeals court, however, recently overturned the FCC's conclusion
that calls to Internet service providers are necessarily interstate. Further,
FCC and judicial decisions on this issue may impact inter-carrier compensation
for calls to Internet service providers, which could affect Internet service
providers' costs.

     In addition, because users may download materials and subsequently
distribute them to others, persons may potentially make claims against
post-merger CoreComm for defamation, negligence, copyright or trademark
infringement, personal injury or other claims based on the nature, content,
publication and distribution of these materials. Post-merger CoreComm also could
be exposed to liability with respect to the offering of third-party content that
may be accessible through its services. It is also possible that if any
third-party content provided through post-merger CoreComm's services contains
errors, third parties who access this material could make claims against
post-merger CoreComm for losses incurred in reliance on this information.
Post-merger CoreComm also will offer e-mail services, which will expose it to
other potential risks, such as liabilities or claims resulting from unsolicited
e-mail, lost or misdirected messages, illegal or fraudulent use of e-mail or
interruptions or delays in e-mail service. These claims, whether with or without
merit, likely would divert management's time and attention, may result in
negative publicity and could result in significant costs to investigate and
defend.

   POST-MERGER CORECOMM'S RELIANCE ON INCUMBENT LOCAL EXCHANGE CARRIERS AND
   OTHER FACILITIES-BASED PROVIDERS OF TELECOMMUNICATIONS SERVICES AND CHANGES
   TO ITS AGREEMENTS WITH THESE PROVIDERS COULD HAVE A MATERIAL ADVERSE EFFECT
   ON IT.

     Post-merger CoreComm will depend upon its agreements with the incumbent
local exchange carriers operating in our existing and targeted markets. There
are two primary types of agreements that we enter and post-merger CoreComm will
enter into with these providers:

     - interconnection agreements, which specify how we or post-merger CoreComm
       connect our or its network with the network of the incumbent local
       exchange carriers in each of our or its markets; and

     - resale agreements, through which we or post-merger CoreComm provide
       telecommunications services on a resale basis.

     Federal legislation regulating the telecommunications industry has enhanced
competition in the local service market by requiring the incumbent local
exchange carriers to provide access to their networks through interconnection
agreements and to

                                       36
<PAGE>   50

offer separate elements of their network and retail services at prescribed rates
to other telecommunications carriers. The termination of any of post-merger
CoreComm's contracts with its carriers or a reduction in the quality or increase
in cost of their services could have a material adverse effect on post-merger
CoreComm's financial condition and results of operations.

     Our interconnection agreements require the incumbent local exchange
carriers to provide sufficient transmission capacity to keep blocked calls
between our networks within industry limits. Accordingly, we are and post-merger
CoreComm will be partially dependent on the incumbent local exchange carriers to
provide customers with superior service and avoid blocked calls. The failure by
the incumbent local exchange carriers to comply with their obligations under
post-merger CoreComm's interconnection agreements could result in customer
dissatisfaction and the loss of existing and potential customers. In addition,
the rates charged to post-merger CoreComm under the interconnection agreements
may limit its flexibility to price its services at rates that are low enough to
attract a sufficient number of customers and permit post-merger CoreComm to
operate profitably.

     Interconnection agreements are subject to review and approval by various
federal and state regulators. In addition, parties to the agreements may seek to
have the agreements modified based upon the outcome of regulatory or judicial
rulings occurring after the dates of the agreements. The outcome of these
rulings, or any modified agreements, could have a material adverse effect on
post-merger CoreComm's financial condition and results of operations. In
addition, some aspects of interconnection agreements, including the price and
economic terms of these agreements, have been subject to litigation and
regulatory action. Please refer to the section of this joint proxy statement and
prospectus entitled "Government Regulation of the Telecommunications Service
Business."

     We rely on telecommunications carriers to transmit our traffic over local
and long distance networks. Our dependence on other facilities-based carriers
means that post-merger CoreComm will depend on the quality and condition of
their networks. These networks may experience disruptions that are not easily
remedied. Thus, the following conditions of the facilities-based carriers could
cause interruption in service and/or reduced capacity for post-merger CoreComm's
customers:

     - physical damage;

     - power loss; and

     - software defects.

     We depend upon cooperation with the incumbent local exchange carriers and
other providers for the provision and repair of transmission facilities and to
provide the services and network components that are ordered. Post-merger
CoreComm may not be able to obtain the facilities and services it requires at
satisfactory quality levels, rates, terms and conditions, which could delay the
buildout of its networks and degrade the quality of service to its subscribers.
In particular, post-merger CoreComm will depend upon the quality of copper lines
owned by telephone companies that deliver services to its end

                                       37
<PAGE>   51

users. Particularly sensitive to the quality of these lines will be post-merger
CoreComm's DSL offering. The quality of service post-merger CoreComm will be
able to provide through that offering will depend in part on the quality of the
copper lines.

     In addition, post-merger CoreComm will depend upon certain suppliers of
network services, hardware and software. If these suppliers fail to provide
network services, equipment or software in the quantities, at the quality levels
or at the times required, or if post-merger CoreComm cannot develop alternative
sources of supply, it will be difficult, if not impossible, for post-merger
CoreComm to provide its services.

     The pace at which post-merger CoreComm is able to add new customers and
services could be adversely affected if the incumbent local exchange carriers do
not provide it with necessary network elements, collocation space, intercompany
network connections and the means to share information about customer accounts,
service orders and repairs on a timely basis. In addition, post-merger
CoreComm's ability to provide high-speed data services through technologies such
as DSL will be dependent on post-merger CoreComm's ability to obtain space from
the various incumbent local exchange carriers for situating its equipment in the
incumbent local exchange carriers' central offices and elsewhere. In many
instances, the incumbent local exchange carriers do not timely or fully provide
these services or facilities. Also, the rules governing which elements the
incumbent local exchange carriers must provide, the cost methodology for
providing these elements, and the types of equipment that may be placed together
are currently under FCC and judicial review.

     In the event that post-merger CoreComm's long distance carriers are unable
to handle the growth in customer usage, it could try to transfer traffic to a
carrier with sufficient capacity, but we cannot be sure that additional capacity
will be available. If any of the local exchange carriers are unable to handle
the growth in customer usage, post-merger CoreComm will be required to use
another local carrier, which could be difficult in light of the limited number
of local carriers with their own facilities. In the event post-merger CoreComm
elects to use other carriers, the charges for services may exceed those under
the existing contracts, which could have a material adverse effect on
post-merger CoreComm's financial condition and results of operations.

     In addition, the accurate and prompt billing of post-merger CoreComm's
customers will be dependent upon the timeliness and accuracy of call detail
records provided by the carriers whose services it will resell. We cannot be
sure that post-merger CoreComm's carriers will continue to provide accurate
information on a timely basis. A carrier's failure to do so could have a
material adverse effect on post-merger CoreComm's ability to bill its customers
and, therefore, on its operating results.

  POST-MERGER CORECOMM'S PLANNED LOCAL MULTIPOINT DISTRIBUTION SERVICE SYSTEM
  INVOLVES NEW AND LARGELY UNTESTED TECHNOLOGY, SO THERE IS A RISK THAT
  UNANTICIPATED TECHNICAL PROBLEMS WILL CAUSE DIFFICULTIES FOR THIS BUSINESS.

     Post-merger CoreComm's planned local multipoint distribution service
high-speed wireless telecommunications system will use new technology with a
limited operating history whose system architecture remains subject to further
development and

                                       38
<PAGE>   52

refinement. In the past, other companies using local multipoint distribution
service have experienced technical difficulties, some of which have affected
subscriber acceptance of their systems. Additional technical issues may arise in
the course of system deployment that could adversely affect reception quality
and post-merger CoreComm's ability to cover different service areas. In
addition, we believe that a significant percentage of the households in
post-merger CoreComm's local multipoint distribution service markets may be
located in "shadowed" areas capable of receiving the transmitted signal only
with the assistance of "repeaters," which post-merger CoreComm may deploy.
Two-way services that post-merger CoreComm may launch will require the
development and mass production of special equipment. We cannot be sure that the
equipment needed for two-way services will become commercially available at an
acceptable cost. You should also be aware that post-merger CoreComm's ability to
support high service volumes will be limited to the technology involved in local
multipoint distribution service, including limited available bandwidth.

  POST-MERGER CORECOMM MAY NOT BE ABLE TO SUCCESSFULLY IMPLEMENT ITS BUSINESS
  STRATEGY BECAUSE DOING SO DEPENDS ON FACTORS BEYOND ITS CONTROL, WHICH COULD
  ADVERSELY AFFECT ITS RESULTS OF OPERATIONS.

     Post-merger CoreComm's success depends on its ability to implement its
business strategy in order to increase its earnings and cash flow. Post-merger
CoreComm's results of operations and cash flow will be adversely affected if it
cannot fully implement its business strategy. Successful implementation depends
on factors specific to the telecommunications industry and numerous other
factors beyond its control. These include changes in:

     - general economic conditions;

     - adverse changes in local markets;

     - lack of attractiveness of a particular product;

     - evolving consumer preferences;

     - federal, state and local regulations;

     - risks of product tampering; and

     - its continued ability to hire and retain qualified management personnel.

     In addition, because of these and other factors, post-merger CoreComm may
not be able to implement its expansion and business plans, including the
construction of the Smart LEC network, within planned time periods and budgets.
If post-merger CoreComm cannot implement its expansion and business plans in a
timely fashion or if there are delays or cost overruns, post-merger CoreComm's
business, financial condition and results of operations will be adversely
affected.

                                       39
<PAGE>   53

  BECAUSE OF THE FAST PACE OF TECHNOLOGICAL CHANGE IN THE TELECOMMUNICATIONS
  INDUSTRY, THERE IS A RISK THAT POST-MERGER CORECOMM WILL FALL BEHIND OR WILL
  FAIL TO SUCCESSFULLY ADDRESS THIS CHANGE, WHICH COULD HARM ITS ABILITY TO
  COMPETE AND COULD MATERIALLY AND ADVERSELY AFFECT ITS BUSINESS AND RESULTS OF
  OPERATIONS.

     The telecommunications industry is subject to rapid and significant changes
in technology. We cannot predict the effect of technological changes on
post-merger CoreComm's business. However, the cost of implementing emerging and
future technologies may be significant.

     The Internet services market is characterized by rapid technological
change, evolving industry standards, changes in member needs and frequent new
service and product introductions. Post-merger CoreComm's future success
depends, in part, on its ability to use leading technologies effectively,
develop its technical expertise, enhance its existing services and develop new
services that meet changing member needs on a timely and cost-effective basis.
In particular, post-merger CoreComm must provide subscribers with the
appropriate products, services and guidance to best take advantage of the
rapidly evolving telecommunications industry. Post-merger CoreComm's failure to
respond in a timely, cost-efficient and effective manner to new and evolving
technologies, such as those offering greater bandwidth services, among others,
could have a negative impact on its business and financial results.

  POST-MERGER CORECOMM'S INTERNET BUSINESS DEPENDS ON CONTINUED GROWTH OF THE
  INTERNET AS A MEDIUM OF COMMUNICATION AND COMMERCE.

     Post-merger CoreComm's future success in the Internet service provider
business substantially depends on continued growth in the use of the Internet.
Although we believe that Internet usage and popularity will continue to grow, it
cannot be certain that this growth will continue or that it will continue in its
present form. If Internet usage declines or evolves away from post-merger
CoreComm's business, its growth in this case will slow or stop and its financial
results may suffer.

  POST-MERGER CORECOMM'S SERVICES WILL DEPEND UPON ITS NETWORK INFRASTRUCTURE,
  AND THE FAILURE TO HAVE SUFFICIENT CAPACITY TO ACCOMMODATE NEW USERS, TO
  MAINTAIN RELIABILITY OR TO MAINTAIN SECURITY COULD HAVE A MATERIAL ADVERSE
  EFFECT ON POST-MERGER CORECOMM'S ABILITY TO ATTRACT AND RETAIN CUSTOMERS.

     Success in post-merger CoreComm's businesses depends, in part, on the
capacity, reliability and security of its network infrastructure. Network
capacity constraints may occur in the future, both at the local and national
levels. These capacity constraints would result in slowdowns, delays or
inaccessibility when members try to use a particular service. Poor network
performance could cause customers to discontinue service with post-merger
CoreComm. Reducing the incidence of these problems will require constantly
expanding and improving post-merger CoreComm's infrastructure, which could be
very costly and time consuming.

     Our Internet services network infrastructure is composed of a complex
system of routers, switches, transmission lines and other hardware used to
provide Internet access

                                       40
<PAGE>   54

and other services. This network infrastructure will require continual upgrades
and adaptation as the number of customers and the amount and type of information
they wish to transmit over the Internet increases. This development of network
infrastructure will require substantial financial, operational and managerial
resources. We cannot be certain that post-merger CoreComm will be able to
upgrade or adapt its network infrastructure to meet additional demand or
changing customer requirements on a timely basis and at a commercially
reasonable cost, or at all. If post-merger CoreComm fails to upgrade its network
infrastructure on a timely basis or adapt it to an expanding customer base,
changing customer requirements or evolving industry standards, its business
could be adversely affected.

     Post-merger CoreComm will also have to protect its infrastructure against
fire, power loss, telecommunications failure, computer viruses, security
breaches and similar events. We do not currently maintain a redundant or backup
network operations center. A significant portion of Voyager's computer
equipment, including critical equipment dedicated to its Internet access
services, is presently located at two network operating centers: one in East
Lansing, Michigan and the other in New Berlin, Wisconsin. A natural disaster or
other unanticipated occurrence at post-merger CoreComm's switch or collocation
facilities, network operations center or points-of-presence through which
members connect to the Internet, in the networks of telecommunications carriers
post-merger CoreComm will use, or in the Internet backbone in general could
cause interruptions in post-merger CoreComm's Internet services.

  POST-MERGER CORECOMM'S GROWTH STRATEGY AND ACQUISITIONS MAY NOT BE SUCCESSFUL.

     In the future, post-merger CoreComm may acquire or try to acquire products
and businesses from, make investments in, or enter into strategic alliances
with, companies which have products or distribution networks in its current
markets or in areas into which it intends to expand its networks. Any future
acquisitions, investments, strategic alliances or related efforts will be
accompanied by risks such as:

     - the difficulty of identifying appropriate acquisition candidates;

     - the difficulty of assimilating the operations of the respective entities;

     - the potential disruption of post-merger CoreComm's ongoing business;

     - the inability of management to capitalize on the opportunities presented
       by acquisitions, investments, strategic alliances or related efforts;

     - the failure to successfully incorporate licensed or acquired trademarks
       and technology rights into its manufacturing and distribution of its
       products;

     - the inability to maintain uniform standards, controls, procedures and
       policies; and

     - the impairment of relationships with employees and customers as a result
       of changes in management.

     We cannot assure you that post-merger CoreComm will be successful in
overcoming these risks or any other problems encountered with these
acquisitions, investments, strategic alliances or related efforts.
                                       41
<PAGE>   55

  POST-MERGER CORECOMM WILL DEPEND ON THE SERVICES OF A SMALL NUMBER OF KEY
  MANAGEMENT PEOPLE WHO CURRENTLY MANAGE CORECOMM.

     We believe that post-merger CoreComm's success depends to a significant
extent upon the abilities and continued efforts of CoreComm's current senior
management, including George S. Blumenthal, the Chairman of the board of
directors, J. Barclay Knapp, its President, Chief Executive Officer and Chief
Financial Officer and Patty J. Flynt, its Senior Vice President and Chief
Operating Officer. The loss of the services of any of these people could have a
negative effect upon post-merger CoreComm's results of operations and financial
condition. You should be aware that several members of senior management are
officers and/or directors of other companies and that none of these individuals
have entered into employment agreements with post-merger CoreComm.

RISK FACTORS RELATING TO POST-MERGER CORECOMM'S CAPITAL STRUCTURE:

  POST-MERGER CORECOMM WILL HAVE SUBSTANTIAL INDEBTEDNESS, WHICH COULD ADVERSELY
  AFFECT ITS FINANCIAL HEALTH AND PREVENT IT FROM FULFILLING ITS OBLIGATIONS
  UNDER ITS EXISTING DEBT.

     Post-merger CoreComm will assume substantial debt and debt service
obligations from CoreComm and Voyager. As of June 30, 2000, on a pro forma basis
it would have had $351.7 million of consolidated indebtedness outstanding and
$661.4 million of stockholders' equity after giving effect to both the ATX
merger and the Voyager merger. As of the same date, it would have had $304.3
million of consolidated indebtedness outstanding and $476.6 million of
stockholders' equity after giving effect to only the ATX merger, and it would
have had $187.4 million of consolidated indebtedness outstanding and $233.2
million of stockholders' equity after giving effect to only the Voyager merger.
We also expect post-merger CoreComm to seek significant vendor financing from
equipment manufacturers as well as other additional debt financing arrangements.

     The substantial amount of debt that post-merger CoreComm will have and that
it or its subsidiaries may incur in the future could have important consequences
for you. For example, it could:

     - limit post-merger CoreComm's ability to obtain additional financing, if
       needed, for working capital, capital expenditures, acquisitions, debt
       service requirements or other purposes;

     - increase post-merger CoreComm's vulnerability to adverse economic and
       industry conditions;

     - require post-merger CoreComm to dedicate a substantial portion of its
       cash flow from operations to payments on its debt and accordingly reduce
       funds available for operations, future business opportunities or other
       purposes;

     - limit post-merger CoreComm's flexibility in planning for, or reacting to,
       changes in post-merger CoreComm's business and the industry in which it
       competes; and

     - place post-merger CoreComm at a competitive disadvantage compared to its
       competitors that have less debt.

                                       42
<PAGE>   56

  RESTRICTIONS IMPOSED BY POST-MERGER CORECOMM'S DEBT AGREEMENTS MAY
  SIGNIFICANTLY LIMIT ITS ABILITY TO EXECUTE ITS BUSINESS STRATEGY AND INCREASE
  THE RISK OF DEFAULT UNDER ITS DEBT OBLIGATIONS.

     Any debt instruments for future indebtedness incurred by post-merger
CoreComm or its subsidiaries are expected to contain a number of covenants that
may significantly limit post-merger CoreComm's or its subsidiaries' ability to,
among other things:

     - borrow additional money;

     - make capital expenditures and other investments;

     - pay dividends;

     - merge, consolidate or dispose of assets; and

     - enter into transactions with related entities.

     In addition, in the future, post-merger CoreComm's debt instruments or
those of its subsidiaries may contain financial maintenance covenants. If the
affected company fails to comply with these covenants, it will be in default
under the applicable debt instrument. A default, if not waived, could result in
acceleration of indebtedness, in which case the debt would become immediately
due and payable. If this occurs, post-merger CoreComm may not be able to repay
its debt or borrow sufficient funds to refinance it. Even if new financing is
available, it may not be on terms that are acceptable. In addition, complying
with these covenants may cause post-merger CoreComm to take actions that it
otherwise would not take, or refrain from actions that it otherwise would take.

  POST-MERGER CORECOMM WILL HAVE ANTI-TAKEOVER DEFENSE PROVISIONS THAT MAY DETER
  POTENTIAL ACQUIRORS AND DEPRESS ITS STOCK PRICE.

     Post-merger CoreComm's certificate of incorporation and by-laws will
contain provisions that could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, control of post-merger CoreComm. These provisions include the
following:

     - post-merger CoreComm will be able to issue preferred stock with rights
       senior to those of its common stock;

     - post-merger CoreComm will have a classified board of directors;


     - post-merger CoreComm's by-laws and certificate of incorporation will
       prohibit action by written consent by stockholders; and


     - post-merger CoreComm's bylaws will require advance notice for nomination
       of directors and for stockholder proposals.

     The indenture for CoreComm's 6% convertible notes, which will become the
obligation of a subsidiary of post-merger CoreComm, also contain provisions that
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from attempting to acquire, control of
post-merger CoreComm. These

                                       43
<PAGE>   57

provisions would require it to make an offer to purchase all of the 6%
convertible notes upon a change of control if required by the noteholders.
Provisions such as these in post-merger CoreComm's or its subsidiaries'
indebtedness may decrease the likelihood that stockholders will receive a
possibly substantial premium for their shares over then current market prices,
and may limit the ability of stockholders to approve transactions that they may
deem to be in their best interest.

     In addition, under the shareholder rights plan that may be adopted by
post-merger CoreComm, holders of its common stock would be entitled to one
preferred share purchase right for each outstanding share of common stock they
hold, exercisable under defined circumstances involving a potential change of
control as discussed in this joint proxy statement and prospectus. If adopted,
the preferred share purchase rights would have the anti-takeover effect of
causing substantial dilution to a person or group that attempts to acquire
post-merger CoreComm on terms not approved by its board of directors. Those
provisions could have a material adverse effect on the premium that potential
acquirors might be willing to pay in an acquisition or that investors might be
willing to pay in the future for shares of post-merger CoreComm's common stock.
Please refer to the section of this joint proxy statement and prospectus
entitled "Description of the Capital Stock of Post-merger CoreComm -- The
Shareholder Rights Plan."

   POST-MERGER CORECOMM MAY HAVE RESTRICTIONS ON DIVIDENDS.

     Neither CoreComm nor Voyager has ever paid a cash dividend in respect of
its stock, and we do not currently intend to do so in the foreseeable future. In
addition, the payment of any dividends by post-merger CoreComm in the future
will be at the discretion of its board of directors and will depend upon, among
other things, future earnings, operations, capital requirements, its general
financial condition, the general financial condition of its subsidiaries and
general business conditions.

     In addition, post-merger CoreComm's or its subsidiaries' present and future
debt instruments may restrict post-merger CoreComm's payment of dividends or the
payment of dividends or distributions to post-merger CoreComm by its
subsidiaries. Please refer to the section of this discussion of risk factors
entitled "Restrictions imposed by post-merger CoreComm's debt agreements may
significantly limit its ability to execute its business strategy and increase
the risk of default under its debt obligations."

RISK FACTORS RELATING TO THE MERGER TRANSACTIONS:

  BECAUSE OF THE CASH COMPONENT OF THE MERGER CONSIDERATION IN BOTH THE ATX
  MERGER AND THE VOYAGER MERGER, CORECOMM WILL BE REQUIRED TO OBTAIN FINANCING
  IN ORDER TO COMPLETE THE MERGERS.

     The consideration in both the ATX merger and the Voyager merger includes
cash, and, therefore, CoreComm intends to undertake either an equity or
debt-based financing in order to fund the cash payments prior to closing. On
August 14, 2000 CoreComm announced that it had received a total of $310 million
of committed financing. This financing is subject to the fulfillment of some
conditions, including obtaining an

                                       44
<PAGE>   58

additional $50 million of financing. See "Summary -- Recent Development" for
more information regarding the financing commitments and conditions.

     Any debt financing that is obtained may have the following effects on
post-merger CoreComm:

     - post-merger CoreComm will likely have a higher degree of leverage than
       CoreComm currently does, resulting in a larger amount of debt service
       costs;

     - any debt instruments to which post-merger CoreComm will be subject as a
       result of financing the mergers will likely have restrictive covenants
       that may limit post-merger CoreComm's ability to obtain additional
       financing to fund future working capital, acquisitions or other needs;

     - the debt instruments may impose financial and other restrictive covenants
       that may limit post-merger CoreComm's flexibility in planning for or
       reacting to changes in its industry; and

     - any equity financing may have the effect of diluting the outstanding
       shares of CoreComm and post-merger CoreComm, and thus may cause a
       decrease in the share price of CoreComm and post-merger CoreComm common
       stock.

  POST-MERGER CORECOMM MAY NOT BE ABLE TO INTEGRATE VOYAGER OR ATX OR ITS OTHER
  RECENT ACQUISITIONS. FAILING TO DO SO WOULD ADVERSELY AFFECT ITS RESULTS OF
  OPERATIONS.

     CoreComm entered into the ATX merger agreement and the Voyager merger
agreement to strengthen its positions in the provision of both Internet and
telephone services and to create the opportunity for potential cost savings.
Achieving the benefits of the ATX merger and the Voyager merger will depend in
part on integrating technology, operations and personnel in a timely and
efficient manner to minimize the risk that the ATX merger and the Voyager merger
will result in the unplanned loss of customers or key employees or the continued
diversion of the attention of management. Another challenge is to demonstrate to
our customers that the ATX merger and the Voyager merger will not result in
adverse changes in client service standards or business focus and persuade our
personnel that the component companies' business cultures are compatible. We
cannot assure you that the ATX merger and the Voyager merger can be successfully
integrated or that any of the anticipated benefits will be realized, and failure
to do so could have a material adverse effect on post-merger CoreComm's
business, financial condition and operating results.

     Moreover, Voyager has expanded its operations rapidly during the past two
years. Much of this growth is attributable to 27 acquisitions that Voyager has
made since July 1998. Furthermore, during 1999, CoreComm acquired MegsINet Inc.
and USN Communications Inc. and is continuing to integrate those acquisitions.
Failure to integrate these acquisitions successfully could have a material
adverse effect on post-merger CoreComm's business, financial condition and
operating results.

                                       45
<PAGE>   59

GENERAL RISK FACTORS:

  MANY OF POST-MERGER CORECOMM'S OFFICERS AND DIRECTORS FACE POTENTIAL CONFLICTS
  OF INTEREST BECAUSE THEY ARE OFFICERS AND DIRECTORS OF OTHER COMPANIES IN THE
  TELECOMMUNICATIONS INDUSTRY, WHICH COULD IMPEDE THEIR ABILITY TO MAKE
  DECISIONS FOR POST-MERGER CORECOMM. IN ADDITION, SOME OF POST-MERGER
  CORECOMM'S OFFICERS AND OTHER EMPLOYEES ARE EMPLOYED BY POST-MERGER CORECOMM'S
  AFFILIATES.

     Many of post-merger CoreComm's directors and officers are also directors
and officers of other companies in post-merger CoreComm's industry, and some are
employed by historical affiliates of post-merger CoreComm. In addition, some of
post-merger CoreComm's officers and all of its directors are also officers
and/or directors of NTL Incorporated, a commonly managed historical affiliate,
which is a telecommunications company that has historical ties to CoreComm. From
time to time, opportunities may arise that would be pursued by one or more of
these companies and post-merger CoreComm at the same time. In addition, CoreComm
and NTL have entered into various transactions and service arrangements. Because
all of post-merger CoreComm's directors will be directors of NTL, decisions
about these opportunities or transactions may result in conflicts of interest.
In those instances, post-merger CoreComm's board of directors will seek to act,
with the advice of its counsel, in a manner consistent with each director's
duties to post-merger CoreComm and its stockholders under applicable law.

     Furthermore, many of post-merger CoreComm's officers and employees will
allocate their business time between post-merger CoreComm and NTL. These
officers and employees will not be available on a full-time basis to post-merger
CoreComm in the future, and they may have duties to these other companies which
may interfere with their duties to post-merger CoreComm.

RISK FACTORS RELATED TO VOYAGER THAT WILL BE APPLICABLE TO POST-MERGER CORECOMM
PRIMARILY BECAUSE OF THE COMPLETION OF THE VOYAGER MERGER:

   VOYAGER'S OPERATING RESULTS FLUCTUATE.

     Voyager has experienced significant fluctuations in its results of
operations on a quarterly and annual basis, which it expects to continue to
experience in its future quarterly and annual results of operations due to a
variety of factors, many of which are outside of Voyager's control, including:

     - demand for and market acceptance of Voyager's services;

     - customer retention;

     - the timing and magnitude of capital expenditures, including costs
       relating to the expansion of operations and network infrastructure;

     - introductions of new services or enhancements by Voyager and its
       competitors;

     - increased competition in Voyager's markets within the Midwest;

     - growth of Internet use and establishment of Internet operations by
       mainstream enterprises;

                                       46
<PAGE>   60

     - changes in Voyager's and its competitors' pricing policies; and

     - general economic conditions affecting Voyager's industry.

  VOYAGER'S FUTURE SUCCESS DEPENDS SIGNIFICANTLY ON RETAINING EXISTING CUSTOMERS
  AND GENERATING NEW ONES.

     Voyager believes that its long-term success depends largely on its ability
to retain existing customers while continuing to attract new customers. Voyager
has invested significant resources in its network infrastructure and customer
and technical support capabilities to provide high levels of customer care.
Voyager cannot be certain that these investments will maintain or improve its
customer retention rate. Voyager believes that intense competition from its
competitors, some of which offer free hours of service or other enticements for
new customers, has caused, and may continue to cause, some of Voyager's
customers to switch to its competitors' services. Voyager is also susceptible to
losing customers that it acquires through its acquisitions due to the customers'
lack of familiarity with Voyager and the billing and network difficulties that
sometimes occur after an acquisition. In addition, some new subscribers use the
Internet only as a novelty and do not become consistent users of Internet
services and, therefore, may be more likely to discontinue their service. These
factors may adversely affect Voyager's subscriber retention rates, which would
have an adverse effect on its business and operating results.

RISK FACTORS RELATING TO THE TERMS OF THE VOYAGER MERGER AGREEMENT:

  VOYAGER STOCKHOLDERS CANNOT BE CERTAIN OF THE MARKET VALUE OR THE AVERAGE
  TRADING PRICE OF THE POST-MERGER CORECOMM COMMON SHARES THEY WILL RECEIVE FOR
  THEIR SHARES OF VOYAGER COMMON STOCK

     In the Voyager merger, Voyager stockholders will be entitled to receive
0.292 of a post-merger CoreComm common share plus $3.00 in cash for each share
of Voyager common stock they hold.

     If the average per share trading price of CoreComm common shares is less
than $33.03, Voyager has the right to terminate the Voyager merger agreement,
subject to CoreComm's ability to prevent Voyager from doing so. In order for
CoreComm to prevent termination, it would have to increase the fraction of a
post-merger CoreComm common share to be issued to Voyager stockholders for each
Voyager share such that the value of the CoreComm common shares to be included
in the consideration paid for each share of Voyager common stock will not be
lower than $12.02. If CoreComm elects not to exercise this "topping-up" right,
the Voyager merger agreement would then be terminated. However, Voyager may
elect not to exercise its right to terminate the Voyager merger agreement. In
that case, the aggregate value to be received for each share of Voyager common
stock, based on the average trading price, would be less than $15.02.

     If the average per share trading price of CoreComm common shares is less
than $41.17 and at or above $33.03, then the fraction of a post-merger CoreComm
share to be issued to Voyager stockholders for each Voyager share will be
increased such that

                                       47
<PAGE>   61

total merger consideration (including the $3.00 in cash) for each share of
Voyager common stock will not be lower than $15.02. As a result, post-merger
CoreComm could be required to issue more than 0.292 of a post-merger CoreComm
common share in exchange for each share of Voyager common stock.

     If the average per share trading price of CoreComm common shares during a
specified period shortly before the completion of the Voyager merger is at or
below $56.97 and at or above $41.17, for each share of Voyager common stock,
Voyager stockholders will receive 0.292 of a share of post-merger CoreComm stock
plus $3.00 in cash. Because the average trading price of shares of CoreComm
stock may fluctuate while the exchange ratio is fixed, Voyager stockholders
would receive between $15.02 and $19.64 in total merger consideration (including
the $3.00 in cash). Therefore, a decrease in the average trading price of
CoreComm common shares within the range will result in Voyager stockholders
receiving a set number of post-merger CoreComm common shares at a lower value
and thus less total merger consideration.

     If the average per share trading price of CoreComm common shares is greater
than $56.97, the fraction of a post-merger CoreComm common share to be issued to
Voyager stockholders for each Voyager share will be reduced such that total
merger consideration (including the $3.00 in cash) for each share of Voyager
common stock will not exceed $19.64. As a result, Voyager stockholders may
receive less than 0.292 of a post-merger CoreComm common share in exchange for
each share of Voyager common stock.

     If the Voyager merger has not occurred by July 15, 2000 due to reasons
specified in the Voyager merger agreement, the fraction of a post-merger
CoreComm common share to be issued to Voyager stockholders for each Voyager
share will be fixed at 0.292 if the average per share trading price of CoreComm
common shares is at or above $41.17 and no greater than $58.17 (not $56.97). The
upper threshold will increase at a fixed rate for each 31-day period elapsed
after July 31, 2000 in which the Voyager merger is not completed. If these
specified events occur, the value of the consideration (including the $3.00 in
cash) Voyager stockholders will receive for each share of Voyager common stock
may exceed $19.64.

     The average per share trading price of CoreComm common shares is computed
based on the volume weighted-average trading price of CoreComm common shares on
the Nasdaq Stock Market for ten randomly selected trading days out of the 20
consecutive trading days ending on the last trading day prior to closing of the
Voyager merger. However, the actual trading price of CoreComm common shares at
the time of the closing of the Voyager merger may be either higher or lower than
the average trading price, so the actual market value of the post-merger
CoreComm common shares you receive in the Voyager merger may be either higher or
lower than the value of those shares for purposes of calculating the amount of
consideration under the Voyager merger agreement. The average trading price of
CoreComm common stock may vary because of factors such as:

     - changes in the business, operating results or prospects of CoreComm, ATX
       or Voyager;

                                       48
<PAGE>   62

     - market assessments of the likelihood that the Voyager merger or ATX
       merger will occur;

     - the timing of the completion of the Voyager and/or ATX merger;

     - the prospects of operations post-Voyager merger and post-ATX merger;

     - adjustments resulting from stock splits, spin-offs or similar events; and

     - the general market and economic conditions.

     In addition, the exchange of the certificates representing shares of
Voyager common stock for certificates representing shares of post-merger
CoreComm common stock will not take place immediately upon completion of the
Voyager merger. Voyager stockholders will thus be unable to sell or otherwise
transfer these shares of post-merger CoreComm common stock for a period
following the completion of the Voyager merger. The market value of the shares
of post-merger CoreComm common stock may be either lower or higher at the time
Voyager stockholders receive certificates representing shares of post-merger
CoreComm common stock and thus become able to sell those shares, than at the
time of the Voyager merger.

  THE TERMINATION FEE AND VOTING AGREEMENT MAY DISCOURAGE OTHER COMPANIES FROM
  TRYING TO ACQUIRE VOYAGER.

     In the Voyager merger agreement, Voyager agreed to pay a termination fee of
$19.0 million to CoreComm in specified circumstances, including some
circumstances where a third party acquires or seeks to acquire Voyager. This
provision could discourage other companies from trying to acquire Voyager, even
if those other companies might be willing to offer a greater amount of
consideration to Voyager stockholders than CoreComm has offered in the Voyager
merger agreement. Payment of the termination fee would have a material adverse
effect on Voyager's financial condition. In addition, in connection with the
execution of the Voyager merger agreement some of the directors and officers of
Voyager, holding 63.9% of the outstanding shares of Voyager common stock,
entered into a voting agreement with CoreComm. These stockholders agreed to vote
their shares in favor of the Voyager merger agreement and granted CoreComm and
its designees irrevocable proxies to vote their shares in favor of the Voyager
merger. In some circumstances, this agreement will remain in effect for a period
of six months after the Voyager merger agreement is terminated. These provisions
may discourage other companies from trying to acquire Voyager.

RISK FACTORS RELATED TO ATX THAT WILL BE APPLICABLE TO POST-MERGER CORECOMM
PRIMARILY BECAUSE OF THE COMPLETION OF THE ATX MERGER:

   RISK FACTORS RELATING TO THE BUSINESS OF ATX:

  ATX MAY BE REQUIRED TO MAKE SIGNIFICANT CAPITAL EXPENDITURES RELATING TO ITS
  INFORMATION SYSTEMS INFRASTRUCTURE.

     ATX's billing, customer service and management information systems are
vital to its growth and its ability to bill customers, monitor costs and respond
to customer service issues. As ATX continues its transition to being a full
service, integrated telecommunica-
                                       49
<PAGE>   63

tions provider, its need for sophisticated systems will increase. The cost of
implementing these systems has been, and will continue to be, significant.
Additionally, any of the following developments could negatively affect ATX's
business or financial condition:

     - ATX's failure to adequately and timely identify all of its information
       and processing needs;

     - the failure of ATX's systems to operate as expected;

     - ATX's failure to upgrade systems as necessary; and

     - failure by third party service providers to deliver necessary systems or
       services.

  ATX IS A PRIVATE COMPANY AND RELIES TO A SIGNIFICANT EXTENT ON SERVICES AND
  OTHER ASSISTANCE PROVIDED AT MARKET COST BY AFFILIATES AND OWNERS OF ATX. THIS
  ASSISTANCE WILL NO LONGER BE AVAILABLE TO ATX AFTER THE ATX MERGER.

     For fifteen years, ATX has operated as a private company. Only recently has
ATX begun to implement initiatives to create and expand its management
infrastructure so that ATX's growth can be sustained. For instance, ATX
currently shares employees with University City Housing, an entity controlled by
Michael Karp, the Chief Executive Officer and the majority stockholder of ATX.
University City Housing provides general accounting, cash management, tax return
preparation, payroll and human resources services to ATX. Under a transition
services agreement, these arrangements will be provided on a scale that will be
reduced over time following the completion of the ATX merger. Failure to replace
the services and assistance formerly provided by affiliates and owners of ATX on
terms acceptable to ATX could result in material disruptions to the business and
operations of ATX.

   RISK FACTORS RELATING TO THE TERMS OF THE ATX MERGER AGREEMENT:

  THE MARKET PRICE OF POST-MERGER CORECOMM COMMON STOCK AFTER THE ATX MERGER IS
  UNCERTAIN BECAUSE OF THE COMPLEX STRUCTURE OF THE ATX MERGER.

     There is currently no public market for ATX common stock. While it is
believed that the securities markets will recognize that, despite its complex
structure, the ATX merger is actually an acquisition of ATX by CoreComm, and
treat post-merger CoreComm's common stock as it has CoreComm common shares
historically, there can be no assurance that an active trading market will
develop or be sustained. There is uncertainty as to the prices at which the
shares of post-merger CoreComm common stock will trade.

                               VOYAGER.NET, INC.

     Voyager is a large Internet communications company focused in the
Midwestern United States with approximately 368,000 subscribers as of June 30,
2000. Voyager provides high-speed data communications services and Internet
access to residential and business subscribers. Services include high-speed DSL,
providing dedicated telecommunications services to business, cable modem access,
dial-up Internet access, Web-hosting, electronic commerce, situating servers at
a common location and long distance phone services. Voyager operates the largest
dial-up Internet network in the Midwest in terms of geographic coverage, with
approximately 200 Voyager-owned points of presence in Michigan, Wisconsin, Ohio,
Illinois, Indiana and Minnesota. Voyager has competitive local exchange carrier
status in Michigan, Ohio, Indiana and Wisconsin.

INDUSTRY BACKGROUND

     The Internet has rapidly developed into an integral business and personal
communications tool. Consumers and businesses are demanding solutions that
provide them with the ability to access and utilize the Internet in a fast,
secure and reliable manner. Factors driving the growth in the number of Internet
users and Web sites include the large and growing installed base of low-cost
personal computers, advances in the performance and speed of personal computers
and modems, improvements in network infrastructure, easier access to the
Internet and the increasing importance of the Internet as a communications and
commercial medium. Businesses have also rapidly established corporate Internet
sites and connectivity as a means to expand customer reach and improve
communications efficiency. Many businesses are utilizing the Internet as a lower
cost alternative to certain traditional telecommunications services.

     The Internet communications market is highly fragmented. These Internet
service providers vary widely in their geographic coverage, customer focus and
the nature and the quality of their services. The Internet service provider
market is generally segmented into three broad categories:

     - national providers that are typically full-service providers that offer a
       broad range of Internet access and other services to businesses;

     - regional providers that include the regional telephone operators,
       competitive local exchange carriers and Internet access providers, such
       as Voyager; and

                                       52
<PAGE>   66

     - local providers that are typically closely-held start-ups or small
       companies serving a single market.

     The vast majority of Internet communication companies are small, local
operations with fewer than 10,000 customers each.

     Despite the growth in the Internet communications industry, very few
Internet communication companies are profitable. In addition, the dramatic
growth of Internet usage and dependency has prompted customers to demand from
their providers more enhanced technology and services and reliable, high-speed,
quality Internet access. Thus, Internet service providers will be faced with
expending significant capital resources to attract and retain subscribers. As a
result, the industry is expected to undergo substantial consolidation over the
next few years, particularly among the local providers, who typically lack the
financial resources necessary to continue to compete. Voyager believes that the
anticipated growth in Internet use and the significant number of under-
capitalized local providers within its region meeting its acquisition criteria
provides Voyager with an excellent opportunity to extend its scalable business
model.

VOYAGER

     The business model that Voyager has developed has resulted in substantial
revenue and subscriber growth, reduced customer acquisition costs and
significant cash flow from operations and includes customer satisfaction
efforts. Voyager's business model is based on the following key principles:

     - Voyager controls the costs of acquiring new customers by focusing on
       markets in the Midwestern United States, thereby reducing the need for
       more expensive, broad-based marketing campaigns;

     - Voyager focuses on delivering product quality and services and customer
       care, which Voyager believes results in word-of-mouth referrals and
       customer retention greater than the industry average;

     - Voyager manages 100% of its network equipment and customer care
       operations, which reduces its telecommunication costs and enhances
       control over its network utilization, efficiency, scalability and
       quality, and Voyager owns or leases 100% of its network equipment; and

     - Voyager realizes cost savings and economies of scale from its acquired
       businesses by reducing duplicated network infrastructure and taking steps
       to consolidate sales and marketing, network operations, customer support
       and back office operations.

     Voyager has begun to implement a strategy to become a leading provider of
high-speed DSL services in the Midwest. DSL technology is a high-speed Internet
connectivity option using existing telephone wiring, widely heralded as the
next-generation Internet connectivity option. DSL enables connection speeds up
to 50 times faster than using a standard, 28.8 Kbps modem over existing phone
lines. Voyager's DSL deployment strategy will establish a network capable of
providing bundled phone, high-speed Internet and future communications services.

                                       53
<PAGE>   67

     DSL technology is particularly well suited for small and medium-sized
businesses looking to connect their entire staff to the Internet over a single
high-speed Internet connection, or for customers looking to access the Internet
at top speeds. DSL includes the following benefits:

     - provides a dedicated, "always on" connection;

     - is faster than integrated services digital network and modem connections;

     - is more affordable than dedicated T1 and frame relay connections; and

     - is more reliable, and less complicated to use than dial-up connectivity
       options.

     Voyager has a two-tiered strategy to provide DSL services:

     - provide DSL services directly as a competitive local exchange carrier to
       customers in secondary and tertiary markets throughout our region; and

     - continue to provide DSL services through existing relationships with
       major data competitive local exchange carriers in selected major
       metropolitan areas.

     Voyager expects to soon begin deploying DSL services in approximately 40
cities from the central offices of 240 incumbent local exchange carriers,
reaching more than 400,000 small and medium-sized business customers and 3.8
million residential customers. Voyager is targeting secondary and tertiary
markets within its region, covering areas that are less competitive than the
major metropolitan areas. Target markets include Michigan cities of Alpena, Ann
Arbor, Battle Creek, Charlotte, Flint, Gaylord, Grand Rapids, Hastings,
Hillsdale, Jackson, Kalamazoo, Lansing, Petoskey, Sturgis, Three Rivers, and
Traverse City; Ohio cities of Akron, Canton, Dayton, Hamilton, Middletown,
Springfield, Toledo, Troy, and Youngstown; Indiana cities of Columbus, and
Seymour; Illinois cities of Aurora, Elgin, and Joliet; and Wisconsin cities of
Appleton, Kenosha, Madison, Milwaukee, Newberg, Stevens Point, Green Bay, and
Vandyne. When Voyager's DSL network is deployed in these cities, service will be
available in more than 170 cities and townships in the Midwest region.

     Voyager is well positioned to begin offering DSL services directly to its
customers in its Midwest region as it has a strong presence, a large installed
customer base, and a substantial network infrastructure. Voyager's high-speed
strategy is intended to establish Voyager as one of the dominant providers of
DSL services in the Midwest. Voyager's sales and marketing plans include
up-selling its installed customer base as well as attracting customers from
other providers in the region.

                                       56
<PAGE>   70

       customer data communications on its network while also affording
       high-speed access to the Internet. Voyager offers its customers a secure
       network on which to communicate and access information between an
       organization's geographically dispersed locations, collaborate with
       external groups or individuals, including customers, suppliers, and other
       business partners and use the Web to access information on the Internet
       and communicate with other Web users.

     - LONG DISTANCE AND OTHER TELECOMMUNICATIONS.   Voyager currently resells
       long distance telecommunications services as well as an 800 service,
       calling cards and prepaid cards to its Internet customers through its
       VoyagerLink operations. Voyager currently offers this interstate and
       intrastate long-distance service to its customers at a fixed rate per
       minute, with no set-up or monthly charges. Voyager also has begun
       offering bundled voice and data services to customers who seek Internet
       access and telecommunications services from a single source.

SALES AND MARKETING

     Marketing.   Voyager's marketing philosophy is based on the belief that a
consumer's selection of an Internet service provider is often strongly
influenced by a personal referral. Accordingly, Voyager believes that the
customer satisfaction of its subscriber base has led to significant
word-of-mouth referrals. Voyager's referral incentive program awards subscribers
one month of free service for every customer referred. As a result, over 70% of
new sign-ups come from existing subscriber referrals. Voyager's proprietary
customer care and billing system automatically tracks and credits the
subscriber's account, thus providing Voyager with valuable marketing information
and flexibility with this program. Voyager also markets its services through
strategic relationships with value added resellers in the local communities,
such as computer stores, trade associations, unions, Web development companies,
local area network administrators and other retail stores which represent and
promote Voyager on a commission basis. These relationships are a significant
source of new customers. In addition, Voyager offers free Internet training
classes within its markets to cultivate interest in the Internet and increase
brand recognition. Voyager does not use mass marketing media as a major source
of acquiring new customers, but instead believes that by providing superior
customer service and developing strong relationships within local communities,
particularly in small- and medium-sized markets, Voyager can continue to grow at
rates greater than the industry average with very low costs per new customer
acquired.

     Web-based Marketing.   Voyager maintains a Web site (www.voyager.net) that
provides Internet users with the opportunity to learn about Voyager and enroll
in one of its Internet access service plans. Upon viewing information on
Voyager's services, potential customers can either subscribe online or contact a
customer support employee for enrollment. Customers who sign up online or
through Voyager's toll-free number have their accounts created immediately and
are thus able to use their accounts within minutes of account activation.

                                       57
<PAGE>   71

     Free CDs and Diskettes.   Upon the request of prospective customers,
Voyager distributes free software via CD and diskettes that contain both the
Netscape browser software for Windows 95, Windows 3.1 and Macintosh as well as
Microsoft's Internet Explorer 4.0. The software is configured to facilitate
installation and connection to a Voyager point of presence. Individuals
receiving the CD or diskettes have the opportunity to obtain the free browser
software contained on the CD by opening an account with Voyager, either online
or via a toll-free telephone number. New customers can be online in a matter of
minutes after opening an account online or by calling Voyager's toll-free
telephone number.

     Business Sales and Support.   Voyager has a business sales and support team
dedicated to selling and providing customized support to its growing small- and
medium-sized business customers. Voyager's business teams include support
personnel located throughout its target region. This strong local presence
allows it to meet face-to-face with its business customers to evaluate their
needs and respond with customized solutions. Voyager's locally-based sales and
support teams are supported by additional network engineers at its headquarters
for trouble-shooting on specific problems.

CUSTOMER SERVICE AND TECHNICAL SUPPORT

     Voyager provides its customer service and technical support through two
large call centers located in East Lansing, Michigan and New Berlin, Wisconsin.
Voyager provides 100% of its customer care internally and does not outsource any
customer operations to third party providers. Voyager has staffed its call
centers with over 260 employees, or more than 50% of its workforce. Voyager's
two main centers are fully-integrated so that both centers can handle calls from
subscribers located anywhere within the region. This interoperability allows
Voyager to more efficiently handle support calls, thus reducing telephone hold
times. Voyager has upgraded its phone system that routes calls, tracks important
call-in data, automatically answers certain questions and moves customers
quickly through the call-in process. Its comprehensive staff training program
and incentive compensation program linked to customer satisfaction has led to
significant improvements in the time required to move subscribers through the
various calling queues. In addition to using Voyager's call centers, subscribers
can also e-mail questions directly to technical support staff, as well as find
solutions online through the use of the tutorials found at Voyager's Web site.
Voyager's free Internet training and educational classes within its markets also
allow its customers and potential subscribers to ask questions about the
Internet and Voyager's services.

NETWORK AND TECHNOLOGY

     Network Infrastructure.   Voyager designed and built its network to
specifically service Internet (data) traffic. The network is comprised primarily
of the latest Cisco Systems' routing and switching equipment, which provides a
common platform for increased flexibility and maintenance while allowing for the
use of advanced routing protocols to quickly and dependably deliver customer
traffic. Voyager has two network operating centers to oversee traffic flows and
general network operations, as opposed to a single network operating center as
found in many national networks, which helps create

                                       58
<PAGE>   72

redundancy and ensures a secure and reliable network. Voyager is continuously
improving its network infrastructure and connectivity costs through its
relationships with incumbent local exchange carriers such as Ameritech
Corporation and GTE Corporation as well as with competitive local exchange
carriers such as Brooks Fiber (MCI WorldCom), Phone Michigan (McLeodUSA), Time
Warner, Coast to Coast and Focal Communications.

     Voyager's points of presence are linked to regional network points, or
hubs, which are its two network operating centers. These network points are
linked to the Internet by fiber optic connections and employ asynchronous
transfer mode, frame relay and other methods of handling traffic efficiently.
Interlinked network points allow Internet users to access sites located on other
network points. In the event that one of its subscribers wishes to access a Web
site that is located on another service provider's network, data is directed to
a network access point where information sharing is conducted under arrangements
known as peering. The flow of information across a network access point allows
information to be downloaded from one service provider's network to a subscriber
on another service provider's network.

     Points of Presence.   Voyager's approximately 200 dial-in points of
presence primarily utilize digital access servers manufactured by 3Com
Corporation and Lucent Technologies, Inc. These servers allow for a variety of
customer connections from standard dial-up to traditional telecommunications
lines, including integrated digital services network. Voyager's network has been
reconfigured to include redundant data circuits which will automatically route
customer traffic in the event of a failure. Voyager's network topology offers
high levels of performance and security. Through various relationships with
competitive local exchange carriers, Voyager has been able to reduce the overall
number of points of presence by consolidating several of them into "SuperPOPs"
with expanded calling areas. The SuperPOP allows Voyager to consolidate its
equipment into one large modem bank and eliminate various telecommunication
links from its points of presence back to the network operating center, thereby
creating enhanced network reliability and reducing telecommunication costs.
Voyager has worked with its providers to create additional SuperPOPs and Voyager
intends to explore opportunities to create additional SuperPOPs in the future.

     Network Operation Centers.   Voyager has two main network operation
centers, or hubs, in East Lansing, Michigan and New Berlin, Wisconsin. These two
hubs house all of its internal network equipment, including servers, routers,
mail, hosting and disk arrays, as well as its main routing equipment and
connection to the Internet. The two hubs have been interconnected to provide
redundancy and to ensure the highest quality network. The hubs are monitored on
a 24 hours per day, seven days per week basis in order to provide the highest
level of network performance.

     Peering Relationships.   Peering is the act of exchanging data across
networks, typically at specific, discrete locations. By allowing separate
networks to exchange data, users on a particular Internet service provider's
network are able to access information and communicate with users on another
provider's network. Many formal peering points exist where several dozen
Internet service providers and other providers exchange data,

                                       59
<PAGE>   73

including network access points. Internet service providers can also run
connections to peer with several different providers, known as multihoming.
Multihoming allows an Internet service provider to provide better service, as
inbound and outbound data can go over different routes if a particular network
is overloaded. Voyager has relationships at multiple points with several
different organizations, including Verio, Inc. in Ann Arbor, Michigan, NAP.net
in Chicago, Illinois and MCI and Savvis in Kalamazoo, Michigan, thus building in
network redundancy that allows for better connectivity for its customers.

     Integrating Acquired Networks.   As Voyager continues to play a leading
role in consolidating the Internet service provider industry, one of its tasks
is to configure the acquired equipment and network into its regional
Internet-based network. Voyager has taken steps to gain scale economies by
eliminating redundant and expensive Internet connectivity and better utilizing
Voyager's current infrastructure. Its integration plan calls for connecting the
acquired points of presence directly to its network at the most cost effective
point and eliminating duplicate Internet telecommunication costs. Voyager
typically connects within three to six months after the acquisition so as to
allow for a prompt yet smooth integration of the acquired networks and to reduce
service disruptions.

COMPETITION

     The Internet services market is extremely competitive and highly
fragmented. Voyager faces competition from numerous types of providers in its
six state region and anticipates that competition will only intensify in the
future as the Internet service provider industry consolidates. Voyager believes
that the primary competitive factors determining success as an Internet service
provider are:

     - accessibility and performance of service;

     - quality customer support;

     - price;

     - access speed;

     - brand awareness;

     - ease of use; and

     - scope of geographic coverage.

     Voyager believes that it has competed favorably based on these factors,
particularly due to:

     - regionally focused operating strategy;

     - focus on customer care and service;

     - performance of Voyager-owned network facilities; and

     - competitive, multi-tiered pricing policy.

                                       60
<PAGE>   74

     Voyager's current competitors include many large companies that have
substantially greater market presence, brand name recognition and financial
resources. Some of Voyager's local or regional competitors may also enjoy
greater recognition within a particular community. Voyager currently competes,
or expects to compete, with the following types of companies:

     - established online information service providers, which provide basic
       Internet access as well as proprietary information not available through
       public Internet access, such as America Online, Inc.;

     - national Internet service providers, including EarthLink Network, Inc.;

     - numerous regional and local Internet service providers, some of which
       have significant market share in their particular market area;

     - providers of Web hosting, co-location and other Internet-based business
       services, such as Verio, Inc.;

     - computer hardware and software and other technology companies that
       provide Internet connectivity with their products, including IBM and
       Microsoft Corporation;

     - national long distance carriers such as AT&T Corporation, MCI WorldCom
       and Sprint Corporation;

     - regional Bell operating companies and local telephone companies;

     - cable operators, including Tele-Communications, Inc. and Time Warner
       Cable; and

     - nonprofit or educational Internet service providers.

     Many of the major cable companies and some other Internet access providers
have begun to offer or are exploring the possibility of offering Internet
connectivity through the use of cable modems. Cable companies, however, are
faced with large-scale upgrades of their existing plant equipment and
infrastructure in order to support connections to the Internet backbone via
high-speed cable access devices. Voyager believes that there is a trend toward
horizontal integration through acquisitions or joint ventures between cable
companies and telecommunications carriers. Other alternative service companies
have also announced plans to enter the Internet connectivity market with various
wireless terrestrial and satellite-based service technologies. In addition,
several competitive local exchange carriers and other Internet access providers
have launched national or regional digital subscriber line programs providing
high speed Internet access using the existing copper telephone infrastructure.
Several of these competitive local exchange carriers have announced strategic
alliances with local, regional and national Internet service providers to
provide broadband Internet access. Recently, several national access providers
have begun to offer Internet access for free or at substantial discounts to
prevailing rates, which may result in significant pricing pressure. Voyager also
believes that manufacturers of computer hardware and software products, media
and telecommunications companies and others will continue to enter the Internet
services market, which will also intensify competition. Any of these
developments could materially and adversely affect Voyager's business, operating
results and financial condition.

GOVERNMENT REGULATION

     The further deployment of competitive services in the market will continue
to be hampered by incumbent local exchange carrier activities. This is a
challenge not only affecting Voyager, but affects all competitive local exchange
carriers in all states in the country.

     Voyager has begun negotiations of interconnection agreements with the major
incumbent local exchange carriers in its service territories. These agreements
set forth the terms, conditions and rates of Voyager's interconnection with the
incumbent local exchange carriers' telecommunications networks, including, but
not limited to, co-location and UNEs. Under the Federal Telecommunications Act
of 1996, these negotiations are to be commenced upon the competitive local
exchange carriers' written request for negotiations. If an interconnection
agreement is unable to be negotiated within 135-160 days after the incumbent
local exchange carriers' receipt of the written request for negotiation, either
party may petition the state public service commission/ public utility
commission for arbitration of the outstanding issues. Although each state varies
as to its own arbitration practice and procedure, parties generally present oral
and written evidence, participate at hearings at which witnesses are subject to
cross examination, and are allowed to submit briefs and response briefs in
support of their respective positions. 180-210 days after the complaint for
arbitration is filed is the normal time frame within which the state commission
will issue their decision.

     Even if Voyager does not have an interconnection agreement with a
particular incumbent local exchange carrier, Voyager is able to order service
from the incumbent local exchange carrier's tariff in most circumstances. This
allows Voyager to continue to move forward with implementing its business plan
even though Voyager may not have an executed interconnection agreement. Upon
execution of an interconnection agreement, Voyager's continued ordering of
service from the incumbent local exchange carrier will be under the
interconnection agreement in what should be a seamless transition.

     In addition to Voyager's competitive local exchange carrier services,
Voyager provides long distance service as a reseller through its subsidiary
Horizon Telecommunications, Inc. Long distance service consists of both
intrastate and interstate service and therefore is influenced by decisions of
both state commissions and the FCC. Voyager is authorized in all six states in
which it provides long distance service: Indiana, Illinois, Michigan, Minnesota,
Ohio and Wisconsin. As a reseller, Voyager does not have the significant capital
investment in network equipment necessary to provide long distance telephone
service. The state commissions and the FCC have implemented rules and procedures
for the transferring of customers from one provider to another in order to
reduce "slamming," the transfer of the customer from one long distance carrier
to another without the customer's consent. Voyager has long implemented
procedures to obtain a letter of authority, or other approved method (e.g.,
third party verification), to confirm that the customer does in fact want to
change from its current long distance provider to Voyager. Voyager has tariffs
on file with the FCC setting forth the terms, conditions and rates applicable to
its provisioning of long distance service. Although the long distance regulatory
environment is not as active as the local telecommunications arena, it is
difficult to predict how either state and/or federal regulatory authority will
                                       62
<PAGE>   76

impact the provisioning of long distance service in the short or long term. For
more information on government regulation of the telecommunications industry,
please refer to the section of this joint proxy statement and prospectus
entitled "Government Regulation of the Telecommunications Services Business."

INTELLECTUAL PROPERTY

     Voyager has developed and acquired certain proprietary rights for which it
has sought and will continue to seek federal, state and local protection.
Voyager relies on a combination of copyright, trademark and trade secret laws to
protect its proprietary rights, particularly related to its names and logos.
"Voyager.net" and the associated logo are names and marks which belong to
Voyager. In addition, Voyager has registered VoyagerLink and several other
names, marks and logos, and has additional registrations pending for names and
marks, under which it does business at local levels within its region. An
integral part of its successful business strategy is its proprietary Web-based
customer care and billing system. Voyager is exploring whether to seek patent
protection with respect to this customer care system and will act accordingly.
Voyager has each of its employees enter into an inventions agreement under which
each agrees that any intellectual property rights developed while in Voyager's
employment belong to Voyager. Voyager cannot assure you that the steps taken by
it to protect its proprietary rights will be adequate to prevent
misappropriation of its technology or that third parties, including competitors,
will not independently develop technologies that are substantially equivalent or
superior to its proprietary technology.

     In connection with the delivery of its access and other services, Voyager
relies on the use of products of software manufacturers that it bundles in its
software for users with personal computers operating on the Windows or Macintosh
platforms. While some of the applications included in its start-up kit for
access service subscribers are shareware that it has obtained permission to
distribute or that are otherwise in the public domain and freely distributable,
certain other applications included in the start-up kit have been licensed where
necessary. Voyager currently intends to maintain or negotiate renewals of all
existing software licenses and authorizations as necessary, although Voyager
cannot be certain that such renewals will be available to it on acceptable
terms, if at all. Voyager may also enter into licensing arrangements in the
future for other applications.

EMPLOYEES

     As of June 30, 2000, Voyager had 487 employees, including 408 full-time
employees and 79 regular part-time employees. Voyager is not a party to any
collective bargaining agreements covering any of its employees, has never
experienced any material labor disruption and is unaware of any current efforts
or plans to organize its employees. Voyager considers its relationships with its
employees to be good.

PROPERTIES

     Voyager leases each of its office locations. Voyager leases currently cover
in the aggregate approximately 55,000 square feet of space. Voyager has two
primary lease locations which serve as its network operating centers: East
Lansing, Michigan, which is also its corporate headquarters, with approximately
17,000 square feet, which lease

                                       63
<PAGE>   77

expires in 2007; and New Berlin, Wisconsin, where Voyager leases space at four
locations covering in the aggregate approximately 25,000 square feet under
long-term leases. Voyager recently renegotiated its leases in East Lansing and
New Berlin to increase the square feet of space at these facilities to
approximately 32,000 square feet and 67,000 square feet, respectively. The
effective time of each lease is expected to be mid-July. Voyager also leases
space, typically less than 50 square feet per location, to house its network
equipment at each of its points of presence. Voyager does not own any real
estate. Voyager believes that its current facilities are suitable and adequate
for its business and, upon expiration of its leases, Voyager does not anticipate
any significant difficulty in obtaining renewals or alternative space in its
desired markets.

LITIGATION

     Voyager has been, from time to time, involved in various litigation matters
arising in the ordinary course of business. Voyager is not involved currently in
any pending legal proceedings that, either individually or taken as a whole,
will have a material adverse effect on its business, financial condition and
results of operations.

                     ATX TELECOMMUNICATIONS SERVICES, INC.

     ATX offers its customers a full range of high-speed communications services
including long distance, local, wireless and network services such as network
data integration, Internet access and Web consulting, development and hosting
throughout the New York-Virginia corridor. In addition, ATX offers Advanced
Communications Solutions products tailored to meet the needs of its business
customers, such as conference calling, travel services, pre-paid calling,
enhanced fax and PC-based billing. Customers are billed on a single,
consolidated invoice, delivered by traditional means or near real time Web-based
billing that allows the customer to sort the information to detail calling
patterns.

     The predecessors to ATX started operations in 1985. On February 9, 2000,
ATX Telecommunications Services, Ltd., its general partner A.T. Communications,
Inc., Global Telecom Services, Ltd. and its general partner Global
Telecommunications, Inc., merged with and into ATX Telecommunications Services,
Inc., a newly-formed Delaware corporation, which was the surviving corporation.

BUSINESS STRATEGY

     ATX intends to:

     - PROVIDE INTEGRATED COMMUNICATIONS SERVICES AND TARGET HIGH GROWTH
       SECTORS. ATX offers a full complement of high-speed data and
       telecommunications services on a bundled and individual basis for which
       it provides a single bill. ATX believes that providing one-stop
       communications services, including local and long distance services as
       well as data and Internet services, will help ATX to meet the needs of
       its customers, penetrate its targeted markets, capture a larger portion
       of its customers' communications expenditures and increase customer
       retention. ATX is focusing on the following products in an effort to grow
       its revenues: local service, network data integration, Web hosting/Web
       development and Internet service.

                                       64
<PAGE>   78

     - CONTINUE TO DEVELOP A SUPER-REGIONAL NETWORK IN COMMUNICATIONS INTENSIVE
       MARKETS.   ATX's goal is to expand its network reach in the Northeast
       region.

     - TARGET SMALL- AND MEDIUM-SIZED BUSINESSES.   ATX will continue to target
       small-and medium-sized businesses, as well as Fortune 1,000 companies, in
       the New York-Virginia corridor. ATX believes that these customers are
       typically under-served by incumbent local exchange carriers and that they
       will value ATX's ability to provide an integrated suite of advanced
       telecommunications and consulting services on one bill. ATX believes that
       its 15-year operating history and strong presence in its region make it
       well-positioned to exploit this attractive market.

     - EXPAND ATX'S SALES FORCE TO INCREASE REVENUE, MARKET SHARE AND GEOGRAPHIC
       REACH.   With an experienced sales force in the New York-Virginia
       corridor, in an effort to expand its revenues, ATX plans to expand its
       sales force going forward with new offices in southern New England,
       southern New Jersey and New York.

     - CONTINUE TO PENETRATE ENHANCED VOICE AND DATA SERVICES INTO ITS EXISTING
       CUSTOMER BASE.   ATX cross-sells voice and data services to its existing
       customer base. ATX's dedicated client care specialists focus on customer
       service and opportunities to introduce new products to existing accounts.
       Compared with generating new customers, this process is less
       time-intensive due to existing customers' familiarity with ATX and has
       the ability to provide higher revenue margins because it is likely there
       will be lower additional sales expense. Moreover, ATX believes that
       providing additional services significantly increases customer retention.
       Since April 1998, when ATX entered the local service market, ATX has
       delivered local services to approximately 28% of its long distance
       customer base. ATX plans to focus on marketing to its existing customers
       its data products, including network data integration, Web hosting/Web
       development and Internet service.

     - EXPAND SMART-BUILD NETWORK EXPANSION FOCUSED ON CLUSTERED CUSTOMER
       FOOTPRINT. ATX operates a capital-efficient switch and facilities-based
       network that utilizes highly advanced technology. From its inception, ATX
       has used a "smart-build" network strategy, building and owning the
       intelligent components of its network while leasing unbundled local loops
       and inter-exchange transport facilities from other carriers. The purpose
       of this strategy is to allow ATX to enter new markets rapidly,
       selectively target customer clusters, provide low cost redundancy, and
       generate cash flow quickly, while minimizing capital expenditures. As a
       result, approximately 90% of total ATX traffic originates and
       approximately 75% of ATX traffic terminates on its network.

PRODUCTS AND SERVICES

     ATX offers its customers a full range of broadband communications services.
ATX's current product offerings include:

     Long distance.   ATX has offered switched and dedicated long distance
services since its inception in 1985. Long distance services include
inbound/outbound service, international, 800 or 888 service and calling card
telephone service. ATX currently

                                       65
<PAGE>   79

provides intraLATA and interstate long distance services nationwide and
international termination worldwide. ATX also offers a full line of Advanced
Communications Solutions along with long distance, Internet-based call
management, Insight billing applications, traveling calling cards, fax
broadcasting, voice mail, conference calling and enhanced call routing services.

     Local.   ATX's local service was introduced in April 1998. Following its
smart-build strategy, ATX captures market share as a reseller of local service
and then migrates customers on-switch to provide services on an unbundled
network element basis. ATX is focusing on increasing local service penetration
into its existing commercial customer base, expanding its sales force and
broadening its network.

     Network Services.   ATX offers a complete high-speed network solution to
its customers. These services include network data integration for private line
services, Internet services, Web design, development, hosting and consulting
services.

     Internet Services.   ATX utilizes a state-of-the-art network to deliver
Internet access designed for business use, ensuring high-speed, stable
connectivity to a global resource of information. ATX customers are connected
via high-speed dedicated lines, from 56K up to DS3.

     Web Services/E-Commerce.   ATX is able to facilitate virtually every aspect
of establishing and maintaining an interactive global presence in Web services.
The various segments of Web services include Web design, hosting, electronic
commerce, Intranet development, database integration, Internet marketing and
Internet security.

     Consulting Services, Local Area Network/Wide Area Network Data Integration.
ATX's network services and integration unit assists organizations in the design,
construction, implementation and management of practical local and wide area
networks. This business unit manages local area network/wide area network data
integration for private line services, Internet network and integrated services
digital network, as well as professional consulting services and
hardware/software sales. ATX executes efficient and high performance solutions
while educating clients on specific business applications and the technology
that make them possible. Consulting services include wide area network
architecture and implementation, router and CSU configuration, local area
network switching, electronic commerce, cabling and VLAN design and set-up.

     Wireless.   ATX offers portable tools that enable wireless contact
throughout the United States. ATX offers wireless services primarily as a
customer retention tool, consisting of both cellular and paging service. ATX
offers digital and analog cellular services as well as ESMR service, which is
two-way radio and digital cellular service, through Nextel.

     New Products and Services.   ATX believes that DSL, network managed
services and co-location server farm for electronic commerce platforms offer
significant potential for revenue growth. ATX intends to continue focusing its
efforts on advancing these new products and services.

SALES, MARKETING AND DISTRIBUTION

     The ATX sales model is based on its consultative sales approach, its
proprietary marketing and training tools, the experience of its sales force, its
"farm-team" training

                                       66
<PAGE>   80

and career development program, and its shared vision and incentive structure to
reward individual and team performance objectives.

     Each ATX sales consultant provides value to the customer by tailoring
telecommunications products that meet the specific needs of the customer. Each
sale begins with an evaluative consultation that investigates the telecom needs
of the customer. The ATX sales consultant then designs a tailored, integrated
and cost-effective telecom platform that addresses the specific customer's
communications needs. The level of the sales consultant's telecom and customer
knowledge necessary to sell successfully can be achieved only through
significant training, mentoring and devotion of corporate resources.

     ATX has an experienced and long-tenured sales force. Over 25% of ATX's
senior sales force professionals have been with ATX for more than 5 years, and
18 out of 22 members of the sales management team have been promoted from within
the ATX organization. ATX's 243 sales personnel are organized in ten teams,
including sales consultants at all levels.

CUSTOMERS AND PROPRIETARY SYSTEMS

     Customers.   Approximately ninety percent of ATX's customers are located in
the New York-Virginia corridor. No single customer represents more than 2% of
total sales. These customers are typically under-served by the incumbent local
exchange carrier and value ATX's ability to provide an integrated complement of
advanced telecommunications and consulting services on one bill. All of ATX's
revenues are from end-users, with no wholesale, carrier or reciprocal
compensation revenues. In addition, a large portion of ATX's customers are in
industries, such as health services, insurance, legal services, banking and
transportation, that have a high demand for data intensive and comprehensive
telecommunication services.

     Management Information Systems.   ATX has invested in the construction of a
series of proprietary software applications and an extensive corporate Intranet
in its efforts to achieve a paperless work environment in which all job critical
information is readily available online. ATX's employees can use the corporate
Intranet to access detailed product and corporate information, industry research
and updates, competitive intelligence files, online training and certification,
calendars, a personnel directory,

                                       67
<PAGE>   81

community activities, philanthropic organizations, and other important content
from the convenience of their desktops. Online forms and sophisticated e-mail
applications have further increased productivity by enhancing communications at
ATX.

     ATX currently utilizes internally developed proprietary systems for
integrated order management and provisioning, as well as for customer relations
management. For billing, ATX uses a combination of an external service bureau
and proprietary software.

ATX NETWORK ARCHITECTURE

     ATX employs a "smart build" network architecture for the delivery of local
and long distance telephony and data services. Since its predecessors'
inception, ATX has invested capital in switching and networking technologies.
ATX's growth has been through deliberate, planned expansion, resulting in an
efficient heterogeneous, interconnect network connecting the major metropolitan
service areas throughout North America. ATX's network development strategy has
focused around high-density commercial zones where ATX gains control of the
"last mile" of fiber or copper loop via a potential build or a lease. This "last
mile" ultimately connects each customer to the ATX network, which ATX believes
creates a desirable customer dynamic that affords operating efficiencies and
results in higher customer retention rates.

     ATX believes that, in the future, a significant amount of
telecommunications traffic will utilize packet switching technologies. The
current and emerging technologies provide for the encapsulation of all types of
telecommunications services within a common packet switched protocol. As a
result, ATX is currently developing its network towards an Internet network,
packet switched, centric model.

COMPETITION

     The telecommunications industry and all of its segments are highly
competitive and many of ATX's existing and potential competitors have greater
financial, marketing, technical and other resources than does ATX. ATX faces
heavy competition in the telecommunications industry for all of the services it
currently provides and those it intends to provide in the future. Competition
for ATX's products and services is based on price, quality, network reliability,
service features and responsiveness to customers' needs. ATX's strongest
competitors in the long distance market are AT&T and MCI-WorldCom, and to a
lesser degree, emerging competitive local exchange carriers. In the local
market, ATX's strongest competitors are AT&T (Teleport), MCI-WorldCom (MFS) and
Bell Atlantic. In the Internet connectivity market, MCI-WorldCom, Sprint and
some local Internet service providers offering dial-up connectivity in the small
business segment represent ATX's strongest competition. ATX's primary
competitors in the Web development market are local Web development companies.
Competition is relatively strong in the areas of network integration and
integrated access. In other markets, such as data communications and wireless,
ATX faces relatively strong competition.

EMPLOYEES

     As of June 30, 2000, ATX had approximately 600 employees, none of whom are
represented by a labor union or are members of a collective bargaining unit.

                            GOVERNMENT REGULATION OF
                    THE TELECOMMUNICATIONS SERVICES BUSINESS

     The following section describes government regulation that is applicable to
the businesses of CoreComm, Voyager, ATX and post-merger CoreComm.

OVERVIEW

     Many of the telecommunications services that post-merger CoreComm,
CoreComm, Voyager and ATX currently provide and will provide in the future are
regulated by federal, state and local government agencies. The following summary
does not purport to describe all current and proposed regulations and laws
affecting the telecommunications industry. Other existing federal and state
regulations and legislation are the subject of judicial proceedings, legislative
hearings and administrative proposals, which could change in varying degrees the
manner in which this industry operates. Neither the outcome of these proceedings
nor their impact on the telecommunications industry or our business can be
determined at this time. Future federal or state regulations and legislation may
be less favorable to us than current regulation and legislation and therefore
may have a material and adverse impact on our business and financial prospects.
In addition, we may expend significant financial and managerial resources to
participate in proceedings setting rules at either the federal or state level,
without achieving a favorable result.

     At the federal level, the FCC has jurisdiction over interstate and
international services. Interstate services are communications that originate in
one state and terminate in another. State public service commissions exercise
jurisdiction over intrastate services, which are communications that originate
and terminate in a single state. Municipalities and other local government
agencies may also regulate limited aspects of post-merger CoreComm's business,
such as the use of government-owned rights-of-way and construction permits.
Post-merger CoreComm's networks also may have to comply with numerous local
regulations such as building codes, franchise and right-of-way licensing
requirements.

TELECOMMUNICATIONS ACT OF 1996

     The Telecommunications Act of 1996 has resulted and will continue to result
in substantial changes in the marketplace for telecommunications services. These
changes include opening local exchange services to competition and a substantial
increase in the addressable services for us. Among its more significant
provisions, the Telecommunications Act:

     - removes legal barriers to entry into all telecommunications markets,
       including long distance and local exchange services;

     - requires incumbent local exchange carriers, such as SBC or Bell South, to
       "interconnect" with and provide telecommunications services for resale by
       competitors;

                                       70
<PAGE>   84

     - permits incumbent local exchange carriers, including Bell regional
       operating companies in some circumstances to enter into new markets, such
       as long distance and cable television;

     - relaxes regulation of telecommunications services provided by incumbent
       local exchange carriers and all other telecommunications service
       providers; and

     - directs the FCC to establish an explicit subsidy mechanism for the
       preservation of universal service.

     The FCC was also directed by Congress to revise and make explicit subsidies
inherent in the access charge paid by inter-exchange carriers for use of local
exchange carriers' services.

REMOVAL OF ENTRY BARRIERS

     The provisions of the Telecommunications Act enable post-merger CoreComm to
provide a full range of telecommunications services in any state. Although
post-merger CoreComm will be required to obtain certification from state public
service commissions in almost all cases, the Telecommunications Act limits
substantially the ability of a state public service commission to deny a request
for certification. The provisions of the Telecommunications Act also reduce the
barriers to entry by other potential competitors and therefore increase the
level of competition post-merger CoreComm will likely face in all markets
affected by the Telecommunications Act. Please refer to the section of this
joint proxy statement and prospectus entitled "Risk Factors -- Risk factors
relating to post-merger CoreComm's business."

INTERCONNECTION WITH LOCAL EXCHANGE CARRIER FACILITIES

     A company cannot compete effectively with the incumbent local exchange
carriers in the switched local telephone services market unless it is able to
connect its facilities with the incumbent local exchange carriers' facilities
and obtain access to essential services and resources under reasonable rates,
terms and conditions. The Telecommunications Act places a number of access and
interconnection requirements on all local exchange providers, including
competitive local exchange carriers, with additional requirements placed on
incumbent local exchange carriers. These requirements are intended to provide
access to networks under reasonable rates, terms and conditions. Specifically,
incumbent local exchange carriers must provide the following:

         Separation of Network Elements.   Incumbent local exchange carriers
     must offer access to various parts of their network on a separate basis.
     This requirement allows new competitors such as us to purchase at
     cost-based rates elements of an incumbent local exchange carrier's network
     that may be necessary to provide service to our customers.

         Dialing Parity.   All local exchange carriers must provide dialing
     parity, which means that a customer calling to or from a competitive local
     exchange carrier network cannot be required to dial more digits than is
     required for a comparable call originating and terminating on the incumbent
     local exchange carriers' network.

                                       71
<PAGE>   85

         Telephone Number Portability.   Telephone number portability enables a
     customer to keep the same telephone number when the customer switches local
     exchange carriers.

         Reciprocal Compensation.   The duty to provide reciprocal compensation
     means that local exchange carriers must terminate calls that originate on
     competing networks in exchange for a cost based level of compensation and
     that they are entitled to termination of calls that originate on their
     network at the same level of compensation.

         Resale.   Local exchange carriers generally may not prohibit or place
     unreasonable restrictions on the resale of their telecommunications
     services. In addition, incumbent local exchange carriers must offer these
     services to resellers at a wholesale rate that is less than the retail rate
     charged to end users.

         Collocation.   Subject to space and equipment use limitations,
     incumbent local exchange carriers must permit competitive local exchange
     carriers to install and maintain certain types of their own network
     equipment in incumbent local exchange carriers' central offices and remote
     terminals. The rates, terms and conditions are subject to negotiation and,
     failing agreement, to arbitration before state public utilities
     commissions.

         Access to Rights-of-Way.   All incumbent local exchange carriers,
     competitive local exchange carriers and certain other utilities must
     provide access to their poles, ducts, conduits and rights-of-way on a
     reasonable, nondiscriminatory basis.

     Incumbent local exchange carriers are required to negotiate in good faith
with other carriers that request any or all of the arrangements discussed above.
If a requesting carrier is unable to reach agreement with the incumbent local
exchange carriers within a prescribed time, either carrier may request
arbitration by the applicable state commission.

     The rates charged by incumbent local exchange carriers for interconnection
and separate network elements must be calculated using a forward-looking,
incremental cost methodology, but may still vary greatly from state to state.
These rates must be approved by state regulatory commissions, often following a
lengthy and expensive negotiation, arbitration, and review process. Recurring
and non-recurring charges for local loops and other separate network elements
may change based on the rates proposed by incumbent local exchange carriers and
approved by state regulatory commissions from time to time, which creates
uncertainty about how interconnection and separate element rates will be
determined in the future and which could have an adverse effect on our
operations. In January 1999, the United States Supreme Court upheld the FCC's
authority to adopt national pricing rules for interconnection services,
unbundled network elements, and resale by competitive local exchange carriers.
The Supreme Court left open, however, the question of the legality of the total
element long-run incremental pricing methodology adopted by the FCC. On July 18,
2000, the United States Court of Appeals for the Eighth Circuit vacated and
remanded several of the FCC's pricing rules, which may require the FCC to
implement a new pricing methodology that may be less

                                       72
<PAGE>   86

favorable to competitive local exchange carriers. For example, the Eighth
Circuit overturned the FCC's pricing rule that required the total element
long-run incremental cost of an element to be measured based on the use of the
"most efficient telecommunications technology currently available and the lowest
cost network configuration." The Eighth Circuit did, however, find that the use
of a forward-looking incremental cost methodology is reasonable. Portions of the
Eighth Circuit's July 2000 ruling may be appealed to the Supreme Court.

     While the Telecommunications Act generally requires incumbent local
exchange carriers to offer interconnection, separate network elements and resold
services to competitive local exchange carriers, incumbent local exchange
carriers-to-competitive local exchange carriers interconnection agreements may
have short terms, requiring the competitive local exchange carriers to
renegotiate the agreements. In addition, incumbent local exchange carriers may
not provide timely provisioning or adequate service quality, thereby impairing a
competitive local exchange carrier's reputation with customers who can easily
switch back to the incumbent local exchange carriers. In January 1999, the
United States Supreme Court upheld the FCC's authority to adopt national pricing
rules for interconnection services, separate network elements, and resale by
competitive local exchange carriers.

     On remand from the Supreme Court's January 1999 decision, the FCC adopted
an order on September 15, 1999, which specified the separate elements that
incumbent local exchange carriers must make available to competitors. The FCC
reaffirmed that incumbents must provide separate access to six of the seven
network elements that were listed in the FCC's 1996 order. According to the FCC,
separate access to the seventh item, operator and directory assistance services,
is no longer necessary to facilitate competition. The FCC's order also added
additional separate elements to the list -- subloops, portions of loops and dark
fiber -- but declined, except in limited circumstances, to require incumbent
local exchange carriers to separate the facilities used exclusively to provide
high-speed Internet access and other data services. In addition, the FCC
initiated a further rulemaking proceeding to consider whether carriers should be
able to combine separate elements to provide special access services in
competition with those provided by the incumbent local exchange carriers.
Portions of the FCC's 1999 ruling have been appealed by several parties.

     In February 1999, the FCC determined that calls to Internet service
providers are interstate in nature, thus falling under the FCC's jurisdiction
and outside the scope of the Telecommunications Act's reciprocal compensation
requirements. The FCC initiated a review of compensation arrangements for calls
to Internet service providers but stated that, in the meantime, parties may
voluntarily include reciprocal compensation provisions in their interconnection
agreements and that state commissions may order compensation for termination of
Internet service provider calls. Many states decided to leave intact existing
decisions in favor of reciprocal compensation for Internet service
provider-bound calls. On March 24, 2000, the U.S. Court of Appeals for the D.C.
Circuit overturned the FCC's decision that calls to Internet service providers
are not local. The court found that the FCC had failed to explain adequately its
determination that a call does not

                                       73
<PAGE>   87

"terminate" at an Internet service provider merely because the Internet service
providers then originate further telecommunications that extend beyond state
boundaries. In response to this court ruling, the FCC could restate its original
jurisdictional conclusion, it could determine that calls to Internet service
providers are local, or it could create a new classification for them. If it
concludes that such calls are local, competitive local exchange carriers could
be entitled to reciprocal compensation under the Telecommunications Act for
terminating Internet service provider-bound traffic, which could have a
favorable impact on our revenues. Such a decision, however, could also
potentially lead to more state control over Internet-related services, which
could have a negative effect on our roll out of such services. Legislation has
been introduced in Congress that would declare Internet traffic not to be
subject to reciprocal compensation. Enactment of such a provision could have an
adverse effect on our revenues.

     Several incumbent local exchange carriers have filed petitions at the FCC
and have initiated legislative efforts to effect a waiver of the obligation to
unbundle and offer services for resale with regard to high-speed data or
"advanced" services. In addition, certain incumbent local exchange carriers are
seeking to provide these services on an interLATA (long distance) basis before
they have been granted approval by the FCC pursuant to Section 271 of the
Telecommunications Act to enter the long distance market. Permitting incumbent
local exchange carriers to provision data services through separate affiliates
with fewer regulatory requirements could have a material adverse impact on our
ability to compete in the data services sector. The FCC imposed conditions on
the merger of SBC with Ameritech in October 1999 and on the merger of Bell
Atlantic and GTE in June 2000 that permit the provisioning of advanced data
services via separate subsidiaries under various requirements, some of which
expire in the near term. We cannot predict whether these requirements are
enforceable, nor whether they will deter anticompetitive behavior if they are
enforceable. Bell Atlantic's, now Verizon's, application for long distance
service in New York and SBC's application for long distance service in Texas
have been approved subject to similar separate subsidiary provisions. These
areas of regulation are subject to change through additional proceedings at the
FCC or upon judicial review.

     Although the FCC has held that incumbent local exchange carriers providing
advanced services continue to be required to comply with the resale and
unbundling obligations of the Telecommunications Act, it has started a
proceeding to determine whether incumbent local exchange carriers can create
separate affiliates for advanced services that would be free of these
obligations. In November 1999, the FCC ruled that quality discounts on tariffed
digital subscriber line services that incumbent local exchange carriers provide
to Internet service providers need not be resold to competitive
telecommunications providers at lower wholesale rates.

     The FCC has adopted rules requiring incumbent local exchange carriers to
provide collocation to competitive local exchange carriers for the purpose of
interconnecting their competing networks. Under the rules adopted by the Local
Competition Orders, incumbent local exchange carriers are required to provide
either physical collocation or virtual collocation at their switching offices.
Recently, the FCC established new rules

                                       74
<PAGE>   88

designed to make it easier and less expensive for competitive local exchange
carriers to obtain collocation at incumbent local exchange carrier central
offices by, among other things, restricting the incumbent local exchange
carriers' ability to prevent certain types of equipment from being collocated
and requiring incumbent local exchange carriers to offer alternative collocation
arrangements to competitive local exchange carriers. On March 17, 2000, however,
the U.S. Court of Appeals for the D.C. Circuit overturned several of these
collocation rules, finding that the FCC had failed to make a determination about
whether all the types of equipment incumbent local exchange carriers are
required to collocate is "necessary" for interconnection or access to separate
elements. According to the court, such a determination is required under the
Telecommunications Act. The court also rejected other FCC rules that permit
competitive local exchange carriers to cross-connect their equipment with the
equipment of other competitive local exchange carriers and give competitive
local exchange carriers the option of collocating equipment in any unused space
in an incumbent local exchange carrier central office. While ultimately the FCC
could provide reasoned explanations for its current collocation requirements,
the uncertainty created by this court decision could provide incumbent local
exchange carriers with a basis for refusing to collocate multi-function
equipment or provide collocation in a timely and efficient manner. This could
have a negative impact on our network deployment plans.

     In this March 17, 2000 order, the court also overturned the FCC's
determination that incumbent local exchange carriers must permit collocating
competitive local exchange carriers to cross-connect their facilities. The court
stated that the FCC failed to explain how cross-connects between competitive
local exchange carriers are necessary for interconnection with or access to the
separate elements of the incumbent local exchange carriers. In addition, the
court rejected some of the FCC's provisions regarding the implementation of
physical collocation, such as the requirement that incumbent local exchange
carriers give competitors the option of collocating equipment "in any unused
space." The immediate impact of these rulings is that incumbent local exchange
carriers may seek to hinder physical collocation, driving up collocation costs.
The FCC will have the opportunity to offer explanations for its decisions, but
these explanations may not be issued in the near future. The March 17, 2000
order did uphold FCC rules regarding cost allocation and imposing the
requirement that incumbent local exchange carriers provide cageless and adjacent
collocation.

     On December 9, 1999, the FCC released an order that requires incumbent
local exchange carriers to offer line sharing as a separate network element by
June 6, 2000. Line sharing permits competitive local exchange carriers to use a
customer's existing line to provide DSL services while the incumbent local
exchange carrier continues to use the same line to provide voice service. Prices
for line sharing will be set by the states based on a cost methodology adopted
by the FCC. This decision has been appealed. In the meantime, a number of Bell
regional operating companies have reached agreements to provide line sharing at
no or at very low cost, subject to a true-up once the applicable state
commission sets a price. These cost-based line sharing charges may improve the
business outlook for our Internet-related products and services initiatives.

                                       75
<PAGE>   89

     SBC, through its Project Pronto, is changing its network architecture.
These changes may have an impact on CoreComm's ability to interconnect and
collocate for the provision of DSL services. One of the changes is the
replacement of copper lines with fiber lines in certain parts of the SBC
network. Currently, many types of DSL services can be transmitted only over
copper lines. Another change involves a reduction in the size of remote terminal
facilities in SBC's network. This limits the space available for CoreComm and
other providers to place their DSL equipment in those remote terminal
facilities. SBC may also be deploying DSL-related equipment that is not
compatible for interconnection with competitors' DSL equipment.

     In addition to requiring the incumbent local exchange carriers to open
their networks to competitors and reducing the level of regulation applicable to
competitive local exchange carriers, the Telecommunications Act also reduces the
level of regulation that applies to the incumbent local exchange carriers,
thereby increasing their ability to respond quickly in a competitive market. For
example, the FCC has applied "streamlined" tariff regulation of the incumbent
local exchange carriers, which shortens the requisite waiting period before
which tariff changes may take effect. These developments enable the incumbent
local exchange carriers to change rates more quickly in response to competitive
pressures. The FCC has also adopted heightened price flexibility for the
incumbent local exchange carriers, subject to specified caps. If exercised by
the incumbent local exchange carriers, this flexibility may decrease CoreComm's
ability to compete effectively with the incumbent local exchange carriers in its
markets.

     The Telecommunications Act also gives the FCC authority to decide to
forebear from regulating carriers if it believes regulation would not serve the
public interest. The FCC is charged with reviewing its regulations for continued
relevance on a regular basis. As a result of this mandate, a number of
regulations that apply to competitive local exchange carriers have been, and
others may in the future be, eliminated. We cannot, however, guarantee that any
regulations that are now or will in the future be applicable to us will be
eliminated.

     Congress is considering a number of bills that would deregulate the
provision of advanced services by incumbent local exchange carriers. These
regulatory or legislative outcomes could have an adverse effect on our ability
to obtain access to the network elements necessary for the provision of advanced
services to our customers or to compete with incumbent local exchange carriers
in the provision of such services.

LOCAL EXCHANGE CARRIER ENTRY INTO NEW MARKETS

     Our principal competitor in each local exchange market we enter is the
incumbent local exchange carrier. Bell regional operating companies are
currently permitted to provide long distance services to customers outside of
their local service areas and in conjunction with their mobile telephone service
offerings, but they are prohibited from providing long distance services that
originate in the states where they provide local telephone service, which is
referred to as in-region long distance service. Section 271 of the
Telecommunications Act established procedures under which regional Bell
operating

                                       76
<PAGE>   90

companies can provide in-region long distance services in a state after
receiving approval from the FCC. To obtain approval, the regional Bell operating
companies must comply with a competitive checklist that incorporates, among
other requirements, the interconnection requirements discussed above. Please
refer to the section entitled "Government Regulation of the Telecommunications
Services Business -- Interconnection with Local Exchange Carrier Facilities."

     Approval under Section 271 from the FCC will enable regional Bell operating
companies to provide customers with a full range of local and long distance
telecommunications services. The provision of long distance services by regional
Bell operating companies is expected to reduce the market share of the major
long distance carriers, which may be significant customers of our services.
Consequently, the entry of the regional Bell operating companies into the long
distance market may have adverse consequences on the ability of competitive
local exchange carriers such as us both to generate access revenues from the
inter-exchange carriers and to compete in offering a package of local and long
distance services. On December 22, 1999, the FCC approved an application filed
by Bell Atlantic, now Verizon, seeking authority to begin providing long
distance services to customers located in the State of New York. This action
represented the first Section 271 approval by the FCC, which on June 30, 2000,
also approved SBC's application for Section 271 authority in Texas. We
anticipate that Verizon, SBC and other Bell regional operating companies will
soon initiate similar proceedings to obtain long distance service authority in
other states in which we operate or plan to operate. For example, Verizon
already has begun the necessary regulatory review process in the Commonwealth of
Massachusetts.

COMPETITIVE LOCAL EXCHANGE CARRIER INTERSTATE ACCESS CHARGES

     In addition to charging other carriers reciprocal compensation for
terminating local traffic, CoreComm also collects access charges from carriers
for originating and terminating interexchange traffic. Some interexchange
carriers, including AT&T and Sprint, have challenged the switched access rates
of certain competitive local exchange carriers, and have withheld some payments
for the switched access services that they continue to receive. Although no
formal complaints have been filed against CoreComm, AT&T and Sprint have filed
complaints against other competitive local exchange carriers asserting that such
competitive local exchange carriers' service charges for switched access
services are higher than those of the incumbent local exchange carriers serving
the same territory, and are therefore unjust and unreasonable. These
interexchange carriers have refused to pay competitive local exchange carriers
any originating access charges in excess of the corresponding incumbent rate.
Because CoreComm's access charges are appreciably less than those of some
competitive local exchange carriers, and are lower than the access charges of
smaller incumbents having traffic volumes similar to CoreComm's, CoreComm does
not expect the FCC to require any appreciable reduction in CoreComm's tariffed
rates. In addition, in June 2000, the FCC denied the first complaint brought by
Sprint against another competitive local exchange carrier based solely on a
comparison of the rates of the competitive local exchange carrier to those of
incumbent local exchange carriers in the same territory.

                                       77
<PAGE>   91

RELAXATION OF REGULATION

     Through a series of proceedings, the FCC has established different levels
of regulation for "dominant carriers" and "non-dominant carriers." As a
non-dominant carrier, we are subject to relatively limited regulation by the
FCC. However, at a minimum, we must offer interstate services at just and
reasonable rates in a manner that is not unreasonably discriminatory.

     One goal of the Telecommunications Act is to increase competition for
telecommunications services and thus reduce the need for regulation of these
services. To this end, the Telecommunications Act requires the FCC to streamline
its regulation of incumbent local exchange carriers and permits the FCC to
forbear from regulating particular classes of telecommunications services or
providers. Since post-merger CoreComm is a non-dominant carrier and, therefore,
is not heavily regulated by the FCC, the potential for regulatory forbearance
likely will be more beneficial to the incumbent local exchange carriers than to
us in the long run.

     The Telecommunications Act requires all common carriers, including us, to
charge just and reasonable rates for their services and to file schedules of
these rates with the FCC. These schedules are known as "tariffs" and they
represent a contract between a carrier and its customers. The Telecommunications
Act permits the FCC to "forbear" from enforcing certain provisions of the
Telecommunications Act and the FCC has used this authority to determine that it
is in the public interest to prohibit non-dominant carriers from filing tariffs
for their interstate services. This decision of the FCC and its "mandatory
detariffing" was recently affirmed by the U.S. Court of Appeals for the D.C.
Circuit. Currently, the FCC is not permitting non-dominant carriers to file new
tariffs and will require existing tariffs to be withdrawn by 2001. The FCC's
preclusion of non-dominant interstate carriers from filing tariffs may increase
our exposure to litigation. Currently, tariffs contain provisions limiting the
liability of providers on a variety of issues. In the absence of filed tariffs,
carriers would have to rely on negotiated contracts with each customer to
provide these liability limitations.

     Another FCC decision permits, but does not require, competitive local
exchange carriers to file tariffs for the charges that they levy on interstate
long distance carriers for completing calls to competitive local exchange
carriers' customers. Proposals are pending before the FCC to make detariffing of
access services mandatory for competitive local exchange providers. See
"Government Regulation of the Telecommunications Services Business -- Universal
Service and Access Charge Reform" below.

UNIVERSAL SERVICE AND ACCESS CHARGE REFORM

     On May 8, 1997, the FCC issued an order implementing the provisions of the
Telecommunications Act relating to the preservation and advancement of universal
telephone service. This order requires all telecommunications carriers providing
interstate telecommunications services, including us, to contribute to universal
service support for schools, libraries and rural health care programs. Our
contribution to the federal support funds is calculated based on a percentage of
our gross end-user interstate and international telecommunications revenue.
Although we have already begun contributing

                                       78
<PAGE>   92

to the federal universal service and high cost funds, the amount of our required
contribution changes each quarter. Various states are also in the process of
implementing their own universal service programs. We are currently unable to
quantify the amount of subsidy payments that we will be required to make and the
effect that these required payments will have on our financial condition.

     On July 30, 1999, the United States Court of Appeals for the Fifth Circuit
overturned some of the FCC's rules governing the collection and distribution of
those payments. In October 1999, the FCC released two orders in response to the
Fifth Circuit's decision. One order permits incumbent local exchange carriers to
continue to recover their universal service contributions from access charges or
to establish end-user charges. The second order changed the contribution basis
for school/library funding to eliminate calculations based upon intrastate
revenues. A number of parties have petitioned the Supreme Court to review the
Fifth Circuit's decision. The Supreme Court recently agreed to decide the
constitutionality of the FCC's methodology used to compute universal service
support payments.

     In May 1999, the FCC adopted a framework for a new, forward-looking,
high-cost support mechanism that will provide support for non-rural
telecommunications carriers. The FCC stated that the support mechanism will be
used only to determine federal support and will not impose any obligation on a
state to impose intrastate surcharges. It is not possible to determine at this
time what effect this ruling will have on the level of contributions we are
required to make to either the federal or various state universal service
programs, or if it will become easier for us to become qualified as recipients
of universal service funds when we serve high-cost areas.

     In a related proceeding, on May 16, 1997, the FCC issued an order
implementing reforms to its access charge rules. Access charges are charges
imposed by local exchange carriers on long distance providers for access to the
local exchange network, and are designed to compensate the local exchange
carrier for its investment in the local network. The FCC regulates interstate
access and the states regulate intrastate access. This order required incumbent
local exchange carriers to substantially decrease over time the prices they
charge for switched and special access and changed how access charges are
calculated. These changes are intended to reduce access charges and shift
certain usage-based charges to flat-rated, monthly per-line charges. To the
extent that these rules are effective in reducing access charges, our ability to
offer customers lower-cost access services might be impaired.

     On August 27, 1999, the FCC issued an order implementing further reforms to
its access charge rules. The FCC's order granted most local exchange carriers
greater pricing flexibility and instituted other access charge reforms designed
to increase competition and reduce access charges. These changes could impair
our ability to offer customers lower-cost access services. The FCC also issued a
notice of proposed rulemaking, proposing additional pricing flexibility. In
addition, the FCC has initiated a proceeding to consider whether to adopt rules
constraining competitive local exchange carrier access charges. To the extent
competitive local exchange carrier access charges are reduced, our revenue could
decrease.

                                       79
<PAGE>   93

     On May 31, 2000, the FCC issued an order adopting an integrated interstate
access reform and universal service proposal put forth by a coalition of
incumbent local exchange carriers and inter-exchange carriers. These reforms are
aimed primarily at price cap (incumbent) local exchange carriers, but it is too
early to assess what impact, if any, they will have on CoreComm.

     Some state public service commissions have adopted rules or are currently
considering actions to preserve universal services and promote the public
interest.

LOCAL GOVERNMENT AUTHORIZATIONS

     Many jurisdictions where we may provide services require license or
franchise fees based on a percentage of certain revenues. Because the
Telecommunications Act specifically allows municipalities to charge fees for use
of the public rights-of-way, it is likely that jurisdictions that do not
currently impose fees will seek to impose fees in the future. However, the
amount and basis of these fees have been successfully challenged by several
telecommunications service providers. Federal courts have struck down municipal
ordinances that:

     - do not relate the fees imposed under the ordinance to the extent of a
       provider's use of the rights-of-way;

     - do not relate the fees imposed under the ordinance to the costs incurred
       by the local government in maintaining the rights-of-way; or

     - seek to impose fees based on a concept of the "value" of the use to the
       provider by relating the fees to provider revenues.

     Additionally, because the Telecommunications Act requires jurisdictions to
charge non-discriminatory fees to all telecommunications providers,
telecommunications providers are challenging municipal fee structures that
excuse other companies, particularly the incumbent local exchange carriers, from
paying license or franchise fees, or allow them to pay fees that are materially
lower than those that are required from new competitors such as CoreComm. A
number of these decisions have been appealed and, in any event, it is uncertain
how quickly particular jurisdictions will respond to the court decisions without
a specific legal challenge initiated by us or another competitive local exchange
carrier to the fee structure at issue.

REGULATION OF RESELLERS

     The FCC has defined resale as any activity in which a party, the reseller,
subscribes to the services or facilities of a facilities-based provider, or
another reseller, and then reoffers communications services to the public for
profit, with or without adding value. Resellers are common carriers generally
subject to all rules and regulations placed on providers of the underlying
services by either the FCC or the states in which they operate. The FCC has held
that prohibitions on the resale of common carrier services are unjust,
unreasonable, and unlawfully discriminatory in violation of the
Telecommunications Act. Accordingly, all common carriers must make their
services available for resale at rates, terms, and conditions that do not
unreasonably discriminate against

                                       80
<PAGE>   94

resellers. The Telecommunications Act imposes the additional duty upon incumbent
local exchange carriers to make their services available for resale at wholesale
rates. The FCC adopted specific requirements for determining these wholesale
rates for local telecommunications services. While the United States Supreme
Court upheld the FCC's authority to adopt these rules, the FCC's specific
pricing rules remained subject to further judicial review.

     On July 18, 2000, the United States Court of Appeals for the Eighth Circuit
vacated the FCC's rule that required the incumbent local exchange carriers to
exclude all costs that reasonably can be avoided when an incumbent local
exchange carrier provides a telecommunications service for resale at wholesale
rates to a requesting carrier. The Eighth Circuit ruled that incumbent local
exchange carriers should only exclude those costs that an incumbent local
exchange carrier will actually avoid incurring in the future. To the extent that
the cost of resale services increases as a result of this Eighth Circuit
decision, our operating expenses could increase. This Eighth Circuit ruling may
be appealed to the Supreme Court.

     As to other telecommunications service providers, such as competitive local
exchange carriers and wireless providers, there is no regulation that requires
them to give discounts to resellers below the rates offered to end users of the
same quantities of similar services. The FCC's requirement that wireless
providers offer resale services is currently set to expire on November 24, 2002.

LOCAL MULTIPOINT DISTRIBUTION SERVICE

     The FCC has established a new wireless service referred to as local
multipoint distribution service. The FCC allocated two frequency blocks in each
of 493 Basic Trading Areas in the United States to local multipoint distribution
service: Block A with 1,150 MHz of spectrum in the 28 GHz and 31 GHz bands, and
Block B with 150 MHz in the 31 GHz band. Local multipoint distribution service
licenses are awarded for ten-year terms with renewal expectancies provided to
licensees that make a showing of substantial service in their licensed areas.

     Local multipoint distribution service may be used to provide any kind of
communications service on a common carrier or non-common carrier basis. Radio
frequencies in the 28 and 31 GHz bands are generally capable of only
"line-of-sight" transmission and reception, may receive interference from
certain weather conditions, and do not lend themselves to mobile applications.
Local multipoint distribution service is expected to be used for the delivery of
various broadband services to homes and offices, including telecommunications,
Internet access and two-way video. At least seven other countries, including
Canada and Mexico, have licensed local multipoint distribution service on either
a permanent or experimental basis. Local multipoint distribution service
licensees are expected to be able to provide a wide array of services, two-way
capabilities and high capacity through the use of newer digital equipment and
transmission mechanisms. The FCC expects that Block-A local multipoint
distribution service licensees especially, by applying cellular-style frequency
re-use technology to an already

                                       81
<PAGE>   95

large frequency bandwidth, have the potential to become competitors to incumbent
local exchange carriers and cable operators.

     In the initial auction, CoreComm won 15 Block-A licenses for Basic Trading
Areas encompassing substantially all population centers in the state of Ohio,
for a total bid of $25,241,133. The FCC has since granted CoreComm's 15 local
multipoint distribution service licenses with an effective date of June 8, 1998.

INTERNATIONAL OPERATIONS

     CoreComm already provides international resale services and may ultimately
expand its operations to other countries. The FCC requires every carrier that
originates international telecommunications from within the U.S., either through
the use of its own facilities or on a resale basis, to secure in advance an
authorization from the FCC under Section 214 of the Telecommunications Act.
Additionally, these carriers must file with the FCC a tariff containing the
rates, terms, and conditions of their international service offerings. CoreComm
holds a Section 214 Authorization for both facilities-based and resale
international services and has filed a tariff for its international resale
services.

INTERNET REGULATION

     The FCC currently does not regulate the provision of Internet service,
although it does regulate common carriers that provide elements of the
"backbone" networks on which the Internet is based. Similarly, state public
utility commissions generally do not regulate Internet service, except in some
limited circumstances where incumbent local exchange carriers provide Internet
services. The FCC and some states, however, are reviewing the development of the
Internet and the types of services that are provided through it. For example, if
the FCC should determine that an Internet service provider offers a service that
is an exact substitute for long distance telephone service with the sole
distinction that it is based on a packet-switched network rather than a circuit-
switched network, the FCC may determine that it should impose similar regulation
on the new services.

STATE REGULATION GENERALLY

     Most states require companies to be certified or authorized by the state's
public utility commission in order to provide common carrier services. These
certifications generally require a showing that the carrier has adequate
financial, managerial and technical resources to offer the proposed services in
a manner consistent with the public interest.

     In addition to obtaining certification, in each state, we must negotiate
terms of interconnection with the incumbent local exchange carrier before we can
begin providing switched services. See "Government Regulation of the
Telecommunication Services Business -- Interconnection with Local Exchange
Carrier Facilities." State public utility commissions are required to approve
interconnection agreements before they become effective and must arbitrate
disputes among the parties upon request. We have already entered into
interconnection agreements with Ameritech, which is now a part of SBC,

                                       82
<PAGE>   96

Cincinnati Bell Telephone and Verizon. We have also initiated the process of
negotiations with SBC and Verizon for additional interconnection agreements.
Regulatory changes could require renegotiation of relevant portions of existing
interconnection agreements, or require additional court and regulatory
proceedings.

     We are not presently subject to price regulation based on costs or
earnings. Most states require competitive local exchange carriers to file
tariffs setting forth the terms, conditions and prices for intrastate services.
Some states permit tariffs to list a rate range or set prices on an individual
case basis. Other state requirements may include filing of periodic reports, the
payment of regulatory fees and surcharges and compliance with service standards
and consumer protection rules.

     Several states provide incumbent local exchange carriers with flexibility
for their rates, special contracts (selective discounting) and tariffs,
particularly for services that are considered to be competitive. This pricing
flexibility increases the ability of the incumbent local exchange carrier to
compete with us and constrains the rates we may charge for our services. States
may grant incumbent local exchange carriers additional pricing flexibility. At
the same time, some incumbent local exchange carriers may request increases in
local exchange rates to offset revenue losses due to competition.

     Some states require prior approvals or notification for certain transfers
of assets, customers or ownership of a competitive local exchange carrier and
for issuance of bonds, notes or other evidence of indebtedness or securities of
any nature. Delays in receiving required regulatory approvals may occur.

RECIPROCAL COMPENSATION

     Reciprocal compensation is the compensation paid by one carrier to complete
local calls placed by its customers to customers on another local exchange
carrier's network. Because Internet service providers, such as Voyager, receive
many more calls than they make, we expect that after completion of the Voyager
merger, we will receive significantly more reciprocal compensation than we will
pay. However, as a result of uncertainties in the current regulatory environment
and several trends in the telecommunications business, which are discussed
below, it is not clear by how much CoreComm's revenues from reciprocal
compensation will increase over the next few years.

     Some incumbent local exchange carriers have refused to pay reciprocal
compensation charges that they claim are the result of Internet service provider
traffic because they believe that this type of traffic is outside the scope of
existing interconnection agreements. On February 26, 1999, the FCC issued a
declaratory ruling and Notice of Proposed Rulemaking concerning Internet service
provider traffic. The FCC concluded in that ruling that Internet service
provider traffic is jurisdictionally mixed and largely interstate in nature, and
thus within the FCC's jurisdiction. However, the FCC also determined that there
was no federal rule that governed reciprocal compensation for Internet service
provider traffic at the time that the then-existing interconnection agreements
were negotiated and concluded that it should permit states to determine whether
reciprocal compensation should be paid for calls to Internet service providers
under existing interconnection agreements. The FCC requested comment as to what

                                       83
<PAGE>   97

reciprocal compensation rules should govern this traffic upon expiration of
existing interconnection agreements.

     In light of the FCC's order, state commissions which have previously
addressed this issue and required reciprocal compensation to be paid for
Internet service provider traffic may reconsider and may modify their prior
rulings. Some recent state regulatory commission decisions regarding reciprocal
compensation calls placed to Internet service providers could result in lower
revenues for competitive local exchange carriers, including us, in those states.
The issue remains undecided in various other states. Several incumbent local
exchange carriers, including SBC and Verizon, are seeking to overturn prior
orders that they claim are inconsistent with the FCC's February 26, 1999 order.
The relief they seek includes repayment of reciprocal compensation amounts they
previously paid. The great majority of the state commissions that have
considered the issue since the FCC's February 26, 1999 order have rejected the
incumbent local exchange carriers' arguments and required them to pay reciprocal
compensation for Internet service provider-bound traffic. Only a small minority
of the state commissions that have considered the issue are not requiring
reciprocal compensation for this traffic, at least pending negotiations and a
further FCC decision. A few states are not requiring current payment, but are
requiring a true-up if necessary at the time of the FCC's future decision. In
addition, all of the federal courts that have reviewed this issue on the merits
have upheld state decisions requiring that reciprocal compensation be paid for
internet service provider-bound traffic.

     On March 24, 2000, the U.S. Court of Appeals for the District of Columbia
Circuit vacated the FCC's declaratory ruling that Internet-bound calls,
including Internet service provider calls, are jurisdictionally interstate and
therefore not local calls for which reciprocal compensation is owed. The Court
remanded the proceeding to the FCC for a further review of the nature of these
calls for purposes of reciprocal compensation. CoreComm cannot predict the
impact of the Court's ruling on pending or future proceedings at this time. In
May 2000, the Illinois Commerce Commission, in an interconnection arbitration,
reaffirmed its prior holding that Internet service provider calls are local and
subject to payment of reciprocal compensation. However, the Illinois Commerce
Commission at the same time opened a general proceeding to examine the issues
surrounding the explosion of Internet traffic and its effect on the issue of
reciprocal compensation. A finding that reciprocal compensation is not payable
for Internet service provider traffic in Ohio, Illinois or New York would have
an adverse effect on our future revenues and business strategy.

     As our existing interconnection agreements expire and as we enter new
markets, we must negotiate new reciprocal compensation rates and traffic scope
with each incumbent carrier. We expect that rates for Internet service provider
reciprocal compensation will be lower under new interconnection agreements than
under our existing agreements. A reduction in rates payable for Internet service
provider reciprocal compensation could have an adverse effect on our future
revenues and business strategy.

THE CORECOMM SPECIAL MEETING

     Voting Rights; Votes Required for Approval.   The CoreComm board of
directors has fixed the close of business on August 11, 2000 as the record date
for the determination of the CoreComm shareholders entitled to notice of the
CoreComm special meeting. On August 11, 2000, there were 40,162,454 common
shares of CoreComm, which were held of record by 320 holders. As of July 13,
2000, CoreComm's directors and executive officers and their affiliates
beneficially owned an aggregate of 6,740,437 common shares of CoreComm
(excluding common shares reserved for options), or approximately 22.49% of the
outstanding shares of CoreComm entitled to vote on the proposals.

     The presence, either in person or by proxy, of the holders of a majority of
the outstanding common shares of CoreComm is necessary to constitute a quorum at
the CoreComm special meeting. Assuming the existence of a quorum, the
affirmative vote of the holders of a majority of CoreComm's outstanding common
shares voting at that meeting is required to approve and adopt the Voyager
merger agreement, approve and adopt the ATX merger agreement, approve the
domestication merger, approve and adopt the domestication merger agreement and
approve the increase in CoreComm's authorized share capital. Holders of record
of CoreComm common shares on the CoreComm record date are entitled to one vote
per common share of CoreComm at the CoreComm special meeting.

     If a shareholder attends the CoreComm special meeting, that shareholder may
vote by ballot. However, since many shareholders may be unable to attend the
CoreComm special meeting, those shareholders can ensure that their shares are
voted at the meeting by signing and dating the enclosed proxy card and returning
it in the envelope provided. When a proxy card is returned properly signed and
dated, the CoreComm shares represented by that proxy card will be voted in
accordance with the instructions on the proxy card.

     Shareholders are urged to mark the box on the proxy card to indicate how
their CoreComm common shares are to be voted. If a shareholder returns a signed
proxy card but does not indicate how that shareholder's CoreComm shares are to
be voted, the CoreComm shares represented by the proxy card will be voted "FOR"
all of the proposals. The proxy card also confers discretionary authority on the
individuals appointed by the CoreComm board of directors and named on the proxy
card to vote the CoreComm shares represented on the proxy card on any other
matter that is properly presented for action at the CoreComm special meeting,
including any adjournments or postponements of the special meeting. That
discretionary authority will not be used to vote for adjournment of the CoreComm
special meeting to permit further solicitation of proxies if the shareholder
votes against any proposal.

                                       86
<PAGE>   100

     Any CoreComm shareholder who executes and returns a proxy card may revoke
the proxy at any time before it is voted by:

     - delivery to the Secretary of CoreComm, prior to the special meeting, a
       written notice of revocation bearing a later date or time than the proxy;

     - granting a subsequent proxy; or

     - appearing in person and voting at the CoreComm special meeting.

     Attendance at the CoreComm special meeting will not in and of itself
constitute revocation of a proxy.

     Solicitation of Proxies.   CoreComm will bear its own costs of solicitation
of proxies. The cost of preparing, printing and mailing this joint proxy
statement and prospectus will be paid by the party incurring those expenses.
Brokerage houses, fiduciaries, nominees and others will, upon request, be
reimbursed for their out-of-pocket expenses in forwarding proxy materials to
owners of CoreComm common shares held in their names. In addition to the
solicitation of proxies by use of the mails, proxies may be solicited from
CoreComm shareholders by directors, officers and employees of CoreComm in person
or by telephone, telegraph, facsimile or other appropriate means of
communication. No additional compensation, except for reimbursement of
reasonable out-of-pocket expenses, will be paid to these directors, officers and
employees of CoreComm in connection with the solicitation. In addition, D.F.
King & Co., a proxy solicitation firm, has been engaged by CoreComm to act as
proxy solicitor and will receive fees estimated at $10,000, plus reimbursement
of out-of-pocket expenses. Any questions or requests for assistance regarding
this joint proxy statement and prospectus and related proxy materials may be
directed to:

     Other Matters.   CoreComm is not aware of any business or matter other than
those indicated above that may be properly presented at the CoreComm special
meeting. If, however, any other matter properly comes before the CoreComm
special meeting, the proxy holders will, in their discretion, vote on it in
accordance with their best judgment. Any proposal by a shareholder intended to
be presented at the 2001 annual meeting of shareholders must have been received
by CoreComm at the address listed above not later than December 28, 2000 for
inclusion in CoreComm's proxy statement and form of proxy relating to CoreComm's
2001 annual meeting of shareholders. CoreComm's board of directors will review
any shareholder proposals that are filed as required, and will determine whether
those proposals meet the criteria for inclusion in the proxy solicitation
materials or for consideration at the 2001 annual meeting. Copies of CoreComm's
bylaws are available to shareholders free of charge upon request to Amy Minnick,

THE VOYAGER SPECIAL MEETING

     Voting Rights; Votes Required for Approval.   The Voyager board of
directors has fixed the close of business on August 15, 2000, as the record date
for the determination of the Voyager stockholders entitled to notice of and to
vote at the Voyager special meeting. On August 15, 2000, there were 31,654,758
Voyager common shares outstanding, which were held of record by 94 holders. As
of August 15, 2000, Voyager's directors and executive officers beneficially
owned an aggregate of 20,837,577 shares of Voyager common stock (excluding
shares reserved for options), or approximately 65.8% of the outstanding Voyager
common stock entitled to vote on the merger proposal, which requires the
affirmative vote of a majority of Voyager's outstanding shares of common stock
voting together as a single class. In connection with the execution of the
Voyager merger agreement, certain principal stockholders of Voyager,
beneficially owning 63.9% of the outstanding shares of Voyager common stock,
agreed to vote in favor of the Voyager merger agreement, thus assuring that the
Voyager merger will be approved by the Voyager stockholders and therefore those
principal stockholders have sufficient voting power to assure adoption of the
Voyager merger agreement. Please refer to the section of this joint proxy
statement and prospectus entitled "The Merger Agreements -- The Merger Agreement
between CoreComm and Voyager -- Related Agreements -- The Voting Agreement" for
more information regarding the agreements of the principal stockholders of
Voyager and a description of the rights granted to CoreComm.

     The presence, either in person or by proxy, of the holders of a majority of
the outstanding Voyager shares is necessary to constitute a quorum at the
Voyager special meeting. Assuming the existence of a quorum, the affirmative
vote of the holders of at least a majority of the issued and outstanding shares
of Voyager common stock is required to approve the merger with CoreComm. Holders
of record of Voyager common stock on the Voyager record date are entitled to one
vote per share at the Voyager special meeting.

     If a stockholder attends the Voyager special meeting, that stockholder may
vote by ballot. However, since many stockholders may be unable to attend the
Voyager special meeting, the Voyager board of directors is soliciting proxies so
that each holder of Voyager common stock on the Voyager record date has the
opportunity to vote on the proposals to be considered at the Voyager special
meeting. The Voyager common stock represented by a properly signed, dated and
returned proxy card will be voted in accordance with the instructions on the
proxy card. WITH RESPECT TO ADOPTION OF THE MERGER AGREEMENT WITH CORECOMM, IF A
STOCKHOLDER DOES NOT RETURN A SIGNED PROXY CARD, THAT STOCKHOLDER'S VOYAGER
COMMON STOCK WILL NOT BE VOTED AND THUS WILL HAVE THE EFFECT OF A VOTE "AGAINST"
THE PROPOSAL. SIMILARLY, A BROKER NON-VOTE OR AN ABSTENTION WILL HAVE THE EFFECT
OF A VOTE "AGAINST" THE PROPOSAL.

     Stockholders are urged to mark the box on the proxy card to indicate how
their shares of Voyager common stock are to be voted. If a stockholder returns a
signed proxy

                                       88
<PAGE>   102

card, but does not indicate how their shares of Voyager common stock are to be
voted, the Voyager common stock represented by the proxy card will be voted
"FOR" all of the proposals. The proxy card also confers discretionary authority
on the individuals appointed by the Voyager board of directors and named on the
proxy card to vote the Voyager common stock represented thereby on any other
matter that is properly presented for action at the Voyager special meeting,
including any adjournments or postponements of the special meeting. That
discretionary authority will not be used to vote for adjournment of the Voyager
special meeting to permit further solicitation of proxies if the stockholder

                            THE MERGER TRANSACTIONS

                    THE MERGER BETWEEN CORECOMM AND VOYAGER

BACKGROUND OF THE MERGER BETWEEN CORECOMM AND VOYAGER

     In January, 1998, Voyager retained Chase Securities, Inc. to evaluate
strategic alternatives for Voyager, including the possible sale of Voyager
which, at the time, was privately held. Chase set up an auction process for
exploring these alternatives that continued for approximately a month and a
half. During this auction process in which Chase contacted CoreComm for their
possible interest in such a transaction. On March 16, 1999, CoreComm submitted a
preliminary, non-binding indicative expression of interest to acquire Voyager.
CoreComm and Voyager did not enter into a transaction at that time due to
differences as to the valuation of Voyager. Following the auction process,
Voyager's management decided not to sell Voyager and went ahead with an initial
public offering in July 1999.

     On December 15, 1999, Christopher P. Torto, Voyager's Chief Executive
Officer, was contacted by Albert E. Schneider III, a CoreComm consultant, to
reintroduce CoreComm to Voyager and discuss possible ways in which CoreComm and
Voyager could cooperate. A meeting was scheduled for December 20, 1999 at
Voyager's offices in East Lansing, Michigan.

     On December 20, 1999, Mr. Torto and Glenn Friedly, Voyager's chairman, met
with Mr. Schneider at Voyager's offices. At the meeting, the parties discussed
various potential scenarios for cooperation, including a potential merger of the
companies.

     On December 21, 1999, in light of its preliminary discussions with CoreComm
and its recognition of the significant consolidation occurring in the Internet
services providers market, Voyager engaged Morgan Stanley Dean Witter & Co.
Incorporated to explore the possibility of pursuing a strategic business
combination or possible sale of Voyager.

     On January 17, 2000, Messrs. Torto and Friedly met with Barclay Knapp,
CoreComm's Chief Executive Officer, Patty Flynt, CoreComm's Chief Operating
Officer, Michael Peterson of CoreComm's Corporate Development group and Mr.
Schneider, in New Brunswick, New Jersey for an introductory meeting and to
discuss possible business combinations.

     On January 28, 2000, representatives of CoreComm met with Mr. Torto at
Voyager's offices in order to perform operational due diligence on Voyager.

     On January 30, 2000, Mr. Torto met in Atlanta, Georgia, with executives of
a major Internet service provider to discuss a possible acquisition of Voyager
by that company.

     During the month of January 2000, Morgan Stanley contacted eleven parties,
including a larger Internet service provider, regarding the possible acquisition
of Voyager. Following this contact, a second larger Internet service provider
expressed an interest in Voyager and requested due diligence materials to
further evaluate a potential acquisition.

     On February 2, 2000, Messrs. Torto and Friedly and a representative of
Morgan Stanley, met with Mr. Knapp, Ms. Flynt, Mr. Peterson and Mr. Schneider at
                                       91
<PAGE>   105

CoreComm's offices in Cleveland, Ohio. At the meeting, the parties discussed the
various operating strategies of the two companies.

     On February 3, 2000, Voyager received an oral proposal from the second
major Internet service provider to acquire Voyager. This proposal included
common stock of the second major Internet service provider issued at an exchange
ratio that reflected a ten percent premium to the exchange ratio based on the
then-prevailing market price of Voyager stock and did not include any cash
component. In addition, the second major Internet service provider demanded
exclusivity rights for a period of two weeks. Voyager's management felt that the
proposal was inadequate and that the request for exclusivity was inappropriate
in light of the preliminary status of the discussions between the parties.

     On February 9, 2000, Goldman, Sachs & Co. was engaged by CoreComm to
undertake a study to render an opinion as to the fairness to CoreComm of the
possible acquisition of all or a portion of the stock or assets of Voyager.

     On February 10, 2000, at a regularly scheduled meeting, the Voyager board
of directors discussed at length various growth strategies that might be
available to Voyager. The strategies included possible business combinations
with CoreComm, the two Internet service providers that had already contacted
Voyager and other companies. The Voyager board instructed management to continue
to explore strategic combinations with interested parties.

     On February 15, 2000, representatives of CoreComm met with Chris Michaels,
Voyager's Chief Technology Officer, in East Lansing, Michigan. The purpose of
the meeting was to conduct further due diligence on Voyager's operations.

     Following execution of confidentiality agreements with each of the second
Internet service provider and CoreComm, the parties and their attorneys and
accountants conducted due diligence between February 18-22. Legal counsel for
Voyager began the preparation of preliminary documentation for each of the
proposed business combinations.

     On February 21, 2000, Mr. Schneider met with Mr. Torto in East Lansing,
Michigan to discuss a preliminary term sheet for a transaction with CoreComm.
The main items discussed were valuation, form of consideration, lock-up issues
and numerous employee issues, including the vesting of stock options under
Voyager's stock option plan.

     On February 25, 2000, representatives of Voyager visited CoreComm's offices
in Cleveland to conduct due diligence on CoreComm's operations.

     During the month of February 2000, Morgan Stanley continued discussions
with the two Internet service providers that had already contacted Voyager
regarding the potential sale of Voyager. The second Internet service provider
did not substantially change its offer, which Voyager's management believed to
be inadequate. The first Internet service provider never made a formal offer to
acquire Voyager. Of the other nine other parties contacted by Morgan Stanley,
none made a formal offer to acquire Voyager.

                                       92
<PAGE>   106

     A draft of a proposed merger agreement was sent to CoreComm on March 1,
2000 by Voyager's counsel. CoreComm's counsel began reviewing the draft at that
time.

     On March 2, 2000, Mr. Peterson, on behalf of CoreComm, forwarded proposed
terms for a strategic business combination to Mr. Torto. The proposal
contemplated that CoreComm would acquire 100% of the outstanding capital stock
of Voyager through a merger. The proposed terms offered consideration of $15.00
per share for all of the outstanding shares of Voyager, with $3.00 to be paid in
cash and $12.00 to be paid in CoreComm common shares. In addition, CoreComm
requested a two week period of exclusivity. The letter setting forth the
CoreComm proposal provided that unless it was accepted by March 3, 2000, it
would be withdrawn.

     On March 3, 2000, the Voyager board of directors met in New York, New York.
Mr. Torto described the CoreComm proposal to the Voyager board. Voyager's legal
and financial advisors discussed the process and the CoreComm proposal. It was
agreed that Voyager management would pursue further discussions with CoreComm
regarding the proposed business combination.

     On March 4, 2000, Messrs. Friedly, Torto and John Hayes, a member of
Voyager's board of directors, met telephonically with their legal advisors and
Morgan Stanley to further discuss the structure and terms of the proposed
transaction with CoreComm. During discussions between representatives of Morgan
Stanley and CoreComm on March 4, 2000, after being told by Voyager that the
$15.00 per share offered by CoreComm was inadequate to enter into a transaction,
CoreComm increased the offered consideration to $16.00 per share for all of the
outstanding shares of Voyager, with $3.00 to be paid in cash and $13.00 to be
paid in CoreComm common shares. At that time it was agreed that management would
continue the discussions with CoreComm. It was arranged that the parties along
with their legal and financial advisors would meet in New York, New York on
March 5, 2000.

     On March 5, 2000, the parties along with their legal and financial
advisors, met in New York, New York to discuss the general structure and terms
of the proposed transaction. During this meeting, CoreComm proposed a one week
period of exclusivity. After a lengthy discussion of the material issues that
would be presented by such a transaction, Voyager agreed to an exclusivity
period until Friday, March 10, 2000 at 12:00 noon. CoreComm's counsel continued
their review of the draft Voyager merger agreement and related documents and
provided a revised draft reflecting their comments. The parties agreed to a
meeting the following day to discuss the terms of the proposed transaction in
more detail. Although at this point a number of material terms were not
resolved, the parties had narrowed the issues considerably.

     On March 6, 2000, the parties met again with their legal and financial
advisors. Counsel for Voyager identified open negotiation matters relating to
the proposed transaction. Mr. Peterson and Mr. Schneider met separately with Mr.
Torto to inform him of CoreComm's negotiations to acquire ATX. During the next
several days, Voyager's attorneys and financial advisors began conducting due
diligence on ATX.

                                       93
<PAGE>   107

     On March 7, 2000, the board of directors of CoreComm held a preliminary
meeting at which Messrs. Knapp and Peterson and Richard J. Lubasch, CoreComm's
general counsel, made a presentation to the CoreComm board of the principal
terms of the proposed agreements with Voyager as well as ATX. CoreComm's board
of directors gave approval to continue negotiations with each party.

     On March 9, 2000, the CoreComm board of directors held another meeting at
which Messrs. Knapp, Peterson and Lubasch again discussed the principal terms of
the proposed merger with Voyager. At this meeting, Goldman Sachs delivered a
presentation to the CoreComm board of directors regarding its analysis of the
financial terms of the proposed transaction with Voyager. At the conclusion of
the presentation, Goldman Sachs expressed its willingness to render an opinion
as to the fairness to CoreComm of the consideration to be paid to Voyager under
the proposed Voyager merger agreement, subject to negotiation of a definitive
merger agreement with terms and in a form not materially different to the form
presented at the meeting. After discussion, the CoreComm board unanimously
determined that the proposed Voyager merger agreement, the Voyager merger and
the issuance of common shares of CoreComm in connection with the Voyager merger
were advisable and in the best interests of the CoreComm stockholders, and the
CoreComm board approved the Voyager merger agreement and the related issuance of
the common shares of CoreComm. The CoreComm board also unanimously resolved to
recommend that CoreComm's shareholders approve the issuance of the common shares
of CoreComm under the Voyager merger agreement.

     On the morning of March 10, 2000, CoreComm and ATX issued a joint press
release publicly announcing CoreComm's agreement to buy ATX for approximately
$900.0 million in cash and stock.

     On March 10, 2000, the parties reconvened in New York and continued
discussions to finalize the terms of the proposed merger.

     On March 10, 2000, Messrs. Peterson and Schneider met with Mr. Torto and a
representative of Morgan Stanley to discuss further any open issues. Following
this discussion, Messrs. Torto, Friedly and Hayes, met with Messrs. Knapp,
Peterson and Schneider to discuss CoreComm's strategic direction and plans for
growth. Following such discussions, Mr. Torto continued the negotiation of the
terms of the proposed transaction with Mr. Knapp. At this time, the parties
finalized the economic terms of the transaction and agreed on an exchange ratio
of 0.292 CoreComm common shares for each Voyager share, $3.00 in cash
consideration per Voyager share, and the terms of the collar mechanisms.

     On March 10, 2000, CoreComm and Voyager extended the exclusivity period
until Monday, March 13, 2000 at 12:00 noon.

     From March 10, 2000 through March 12, 2000, definitive agreements to
implement the Voyager merger were finalized by the parties.

     On March 12, 2000, prior to the execution of the definitive merger
agreement, Goldman Sachs delivered its oral opinion to CoreComm management,
which was

                                       94
<PAGE>   108

subsequently confirmed by a written opinion, dated March 12, 2000 and addressed
to the CoreComm board, that as of that date, the stock consideration and the
cash consideration, in the aggregate, to be exchanged by CoreComm under the
merger agreement was fair from a financial point of view to CoreComm.

     On the evening of March 12, 2000, the Voyager board of directors met by
telephone to discuss the proposed merger and the definitive documentation. Legal
counsel for Voyager summarized the status of negotiations and terms of the
definitive documentation for the Voyager board. Morgan Stanley made a financial
presentation to the Voyager board and delivered its opinion that the merger
consideration to be received by the holders of shares of common stock of Voyager
under the Voyager merger agreement was fair from a financial point of view to
Voyager's stockholders. After extensive discussions with its legal counsel and
its financial advisors of the risks and advantages of the proposed transaction
to Voyager and its stockholders, the Voyager board unanimously approved the
proposed Voyager merger, the Voyager merger agreement and the transactions
contemplated by it on the terms discussed at the meeting and authorized
management to complete and execute the definitive Voyager merger agreement.

     On the morning of March 13, 2000, CoreComm and Voyager issued a joint press
release publicly announcing the Voyager merger and the execution of the Voyager
merger agreement.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF CORECOMM; REASONS FOR THE MERGER

     The board of directors of CoreComm has determined that the Voyager merger
is in the best interests of CoreComm and its shareholders and has unanimously
approved and adopted the Voyager merger agreement. ACCORDINGLY, CORECOMM'S BOARD
OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" APPROVAL
AND ADOPTION OF THE VOYAGER MERGER AGREEMENT.

     In reaching the determination that the Voyager merger agreement and the
Voyager merger are in the best interests of CoreComm and its shareholders, the
CoreComm board consulted with CoreComm's management, as well as its financial
advisor, legal counsel and accountants and considered the short-term and
long-term interests of CoreComm and the other acquisitions available to
CoreComm. While the CoreComm board considered all of these factors, it did not
make determinations with respect to each of the factors. Rather, the CoreComm
board made its judgment with respect to the Voyager merger and Voyager merger
agreement based on the total mix of information available to it, and the
judgments of individual board members may have been influenced to a greater or
lesser degree by their individual views with respect to different factors.

     Positive Factors Considered by the CoreComm Board of Directors.   In making
its determination with respect to the Voyager merger, the CoreComm board
considered the following material positive factors:

         Geographic Fit and Concentration.   Voyager operates principally in
     Michigan, Ohio, Wisconsin, Illinois and Indiana, and this coverage
     complements CoreComm's

                                       95
<PAGE>   109

     geographic footprint in this region. In addition, because Voyager's
     subscribers are geographically concentrated, CoreComm will have the ability
     to offer telephone service to Voyager's subscribers.

         Enhanced Position as an Integrated Communications Provider.   The
     Voyager merger will improve CoreComm's ability to market DSL services and
     enlarge its subscriber base, which will enhance CoreComm's overall growth
     potential. In addition, post-merger CoreComm will be able to cross-sell its
     services to both Voyager and CoreComm customers, which will provide an
     excellent opportunity for post-merger CoreComm to generate additional value
     per subscriber. The aggregation of the customer base of CoreComm and
     Voyager will also create a much larger Internet service provider that will
     be better able to compete with other Internet service providers.

         Voyager is a Unique Internet Service Provider Asset.   Voyager is a
     large independent Internet communications company focused on the Midwestern
     United States. Voyager also has a large installed customer base and a
     substantial network infrastructure. Voyager has also focused attention on
     customer care and has been able to achieve good customer retention and
     word-of-mouth referrals.

         Complementary Business Strategies.   Voyager and CoreComm have
     complementary business models and services that will allow CoreComm to
     offer a broader range of the two companies combined services to both
     existing and new customers. Both companies have maintained a customer
     focus, and their businesses rely on their ability to retain and attract
     customers. Voyager's Internet service provider customers fit within
     CoreComm's plan of marketing telephone services to Internet service
     provider customers.

         Strong Balance Sheet.   Following the Voyager merger, post-merger
     CoreComm is expected to have a strong balance sheet. The pro forma equity
     of the two companies combined at December 31, 1999 is approximately $575
     million. In addition, post-merger CoreComm should have access to a broad
     range of financing, including secured and unsecured debt due to increased
     physical assets.

         Management Team.   The Voyager merger will give CoreComm access to an
     experienced management team that has the breadth and depth to effectively
     lead and manage post-merger CoreComm's targeted growth in the Internet
     service provider business, make future acquisitions and develop post-merger
     CoreComm's "Internet-centric" plan.

         Opinion of Goldman, Sachs & Co.   Goldman, Sachs & Co. has delivered
     its written opinion, dated March 12, 2000, to the board of directors of
     CoreComm that, as of that date, the cash consideration and the stock
     consideration, in the aggregate, to be exchanged under the Voyager merger
     agreement was fair from a financial point of view to CoreComm. The opinion
     of Goldman Sachs does not constitute a recommendation as to how any holder
     of CoreComm common shares should vote with respect to the transaction. A
     copy of Goldman Sachs' written opinion is attached to this joint proxy
     statement and prospectus as Annex F, and the

                                       96
<PAGE>   110

     shareholders of CoreComm are encouraged to, and should read this opinion in
     its entirety. Please also see the section of this joint proxy statement and
     prospectus entitled "The Merger between CoreComm and Voyager -- The Opinion
     of Goldman Sachs" for more detailed information regarding Goldman Sachs'
     opinion.

     Negative Factors Considered by the CoreComm Board of Directors.   The
CoreComm board considered the matters described in this joint proxy statement
and prospectus under the heading "Risk Factors" as well as the following
potentially negative factors in its deliberations concerning the Voyager merger.

         Unrealized Benefits.   There is a risk that the potential benefits of
     the Voyager merger may not be realized.

         Loss of Key Management.   There is a risk of management and employee
     disruption associated with the Voyager merger, including the risk that
     despite the efforts of post-merger CoreComm following the Voyager merger,
     key technical, sales and management personnel might not remain employed by
     post-merger CoreComm following the Voyager merger.

         Service Disruptions.   Any disruptions in Voyager's services due to the
     Voyager merger or system failure could result in the loss of existing and
     prospective customers, which is one of the key factors on which Voyager's
     future success is dependent.

         Market Changes.   There is potential for the dial-up Internet service
     provider services to become increasingly commoditized, as more Internet
     service providers start offering dial-up service at lower prices.

         Price Pressures.   There is a possibility that the increased
     competition could lead Internet-service providers to change pricing
     structures, which could negatively affect Voyager's business and financial
     results.

     The CoreComm board concluded that potentially negative factors considered
by it were not sufficient, either individually or collectively, to outweigh the
advantages of the Voyager merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF VOYAGER; REASONS FOR THE MERGER

     The board of directors of Voyager has determined that the terms of the
Voyager merger, the Voyager merger agreement and the transactions contemplated
by the Voyager merger agreement are fair to, and are in the best interests of,
Voyager and its stockholders. Voyager's board of directors has unanimously
approved the Voyager merger and the Voyager merger agreement. ACCORDINGLY,
VOYAGER'S BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS OF VOYAGER VOTE
"FOR" APPROVAL AND ADOPTION OF THE VOYAGER MERGER AND THE VOYAGER MERGER
AGREEMENT.

     In reaching the determination that the Voyager merger and the Voyager
merger agreement are in the best interests of Voyager and its stockholders, the
Voyager board of directors consulted with Voyager management, legal counsel and
accountants and was advised by Morgan Stanley Dean Witter, its financial advisor
in this transaction, and

                                       97
<PAGE>   111

considered the short-term and long-term interests of Voyager. In particular, the
Voyager board of directors considered the following material factors, among
others, all of which it deemed favorable, in reaching its decision to approve
the Voyager merger and the Voyager merger agreement:

     - Value of Consideration to be Received by Voyager Stockholders in the
       Voyager Merger as Compared to Historical and Recent Market Price of
       Voyager Common Stock; Cash Consideration.   Based upon the exchange ratio
       and the closing price of CoreComm common shares on March 10, 2000 (the
       last trading day prior to the public announcement of the Voyager merger),
       Voyager stockholders would receive, subject to adjustment, post-merger
       CoreComm common shares and cash in the Voyager merger having an aggregate
       value of $17.00, representing a 31% premium over the closing price of
       $13.00 for Voyager common stock on March 10, 2000 and a 15% premium over
       $15.00, the price for Voyager common stock at the time of its initial
       public offering. Additionally, the Voyager board of directors viewed as
       favorable the meaningful cash component of the Voyager merger
       consideration of $3.00 per share to be received by Voyager stockholders.

     - Adjustment to Exchange Ratio.   As a result of the Voyager merger, each
       share of Voyager common stock held by a Voyager stockholder at the
       effective time will be exchanged for 0.292 of a post-merger CoreComm
       common share and $3.00 in cash. If the average trading price of common
       shares of CoreComm during a specified period ending shortly before the
       completion of the Voyager merger is at or below $56.97 and at or above
       $41.17, for each share of Voyager common stock, Voyager stockholders will
       receive 0.292 of a share of post-merger CoreComm common stock having a
       value, based on the average trading price, ranging from $12.02 per share
       to $16.64 per share. For more information about this "collar" provision,
       please read the section of this joint proxy statement and prospectus
       entitled "The Merger Agreements -- The Merger Agreement between CoreComm
       and Voyager -- Merger Consideration."

     - Termination Rights of Voyager in the Event of a Decrease in the Price of
       CoreComm Common Stock.   Voyager has the right to terminate the Voyager
       merger agreement and "walk away" from the Voyager merger if the volume
       weighted average closing price per share of the CoreComm common shares
       described above decreases below $33.03, subject to CoreComm's option to
       "top-up" or increase the number of post-merger CoreComm common shares to
       be issued to Voyager stockholders so that the aggregate value of each
       post-merger CoreComm common share to be received by Voyager stockholders
       will be equal to at least $12.02.

     - Voyager's Business, Condition and Prospects.   The Voyager board of
       directors recognized that the market for Internet service providers was
       becoming increasingly competitive and that the industry, which had been
       highly fragmented, was experiencing significant consolidation. The
       Voyager board of directors considered Voyager's plan to remain
       competitive in the rapidly evolving Internet communications industry
       through the roll-out of its strategy to become a leading

                                       98
<PAGE>   112

       provider of broadband DSL services in the Midwest. In order to roll-out
       its DSL plan, Voyager would need greater access to capital and expansion
       of its senior and mid-level management. By merging with CoreComm, the
       Voyager board of directors believed Voyager would enjoy significantly
       greater access to such resources and particularly noted CoreComm's strong
       management team.

     - Structure and Tax-Free Nature of the Voyager Merger.   The Voyager board
       of directors viewed as favorable to its determination the fact that a
       significant portion of the merger consideration to be received by Voyager
       stockholders would be stock rather than cash. This allows the Voyager
       stockholders both to share in any future appreciation of post-merger
       CoreComm and to convert their shares of Voyager common stock into
       post-merger CoreComm common shares on a tax-free basis, although Voyager
       stockholders will be taxed on the lesser of cash received or gain
       realized.

     - Termination Rights of Voyager in the Event of a Superior Acquisition
       Proposal and Termination Fee.   The Voyager merger agreement permits the
       Voyager board of directors to continue to receive unsolicited inquiries
       and proposals regarding other potential business combinations, negotiate
       and give information to third parties, and subject to the satisfaction of
       certain conditions, in the exercise of its fiduciary duties, withdraw or
       modify its recommendation to the Voyager stockholders regarding the
       Voyager merger and enter into an agreement with respect to a more
       favorable transaction with a third party, subject to the payment of a
       $19.0 million termination fee to CoreComm.

     - Increased Market Capitalization.   As of March 10, 2000, on a pro forma
       combined basis, assuming completion of the merger with Voyager and the
       merger with ATX, the total market capitalization of the surviving
       company, based on shares of common stock outstanding, would be
       approximately $2.9 billion, which is considerably greater than the total
       market capitalization of Voyager of approximately $411.0 million on this
       date. Based in part on discussions with its financial advisors, the
       Voyager board of directors believes that this increased total market
       capitalization will provide Voyager stockholders with enhanced liquidity.

     - Morgan Stanley Fairness Opinion.   The board of directors of Voyager
       considered as favorable to its determination the opinion, analyses and
       presentations of Morgan Stanley to the effect, that as of the date of the
       opinion, and based upon and subject to certain matters stated in the
       opinion, the merger consideration to be received by the Voyager
       stockholders was fair from a financial point of view to the stockholders.
       The opinion of Morgan Stanley contains a description of the factors
       considered, the assumptions made and the scope of review undertaken by
       Morgan Stanley in rendering its opinion. A more detailed description of
       Morgan Stanley's fairness opinion is provided below under the caption
       "The Opinion of Morgan Stanley" and the full text of the opinion received
       by the Voyager board of directors is attached as Annex E.

                                       99
<PAGE>   113

     The Voyager board of directors also considered the following potentially
negative factors in its deliberations concerning the Voyager merger:

     - Limited Public Trading History.   CoreComm was spun-off on September 2,
       1998, and consequently, the CoreComm common shares have a limited trading
       history in the public market. The Voyager board of directors, however,
       did note that the value of a CoreComm common share had increased 372%
       from its closing price on the first day after the spin-off to its closing
       price on March 10, 2000, the last trading day prior to the public
       announcement of the Voyager merger.

     - Limited Public Float.   Despite CoreComm's larger total market
       capitalization, the average trading volume of its common shares since the
       September 2, 1998 spin-off is 150,806 as contrasted with the average
       trading volume of Voyager since its initial public offering on July 21,
       1999, excluding the trading volume on July 21, 1999, of 398,276. The
       Voyager board of directors believes that an increased public float will
       result following the completion of the Voyager merger, as well as the ATX
       merger, thus increasing liquidity for Voyager stockholders.

     - Other Potential Transactions May Delay the Completion of the Voyager
       Merger. The Voyager board of directors noted potential transactions by
       CoreComm, including the ATX merger, prior to or simultaneously with the
       completion of the Voyager merger, and the difficulty of evaluating the
       Voyager merger in light of these potential transactions. The Voyager
       board of directors also considered the possibility that the closing for
       the Voyager merger could be delayed until October 31, 2000 or later as a
       result of these transactions. This negative factor was partially offset
       by providing for automatic adjustments to the exchange ratio to allow
       Voyager stockholders to participate in a greater portion of any increases
       in the trading price of CoreComm common shares in the event that the
       Voyager merger is not consummated on or prior to July 15, 2000.

     - Post-Merger CoreComm Will Have Substantial Indebtedness.   The Voyager
       board of directors considered the substantial indebtedness that
       post-merger CoreComm will have after completion of the Voyager merger and
       ATX merger.

     - Successful Implementation of CoreComm Business Strategy May Not be
       Realized. The Voyager board of directors considered the risk that
       CoreComm is in the early growth stage of its development, having been
       formed in September, 1998 from previously owned subsidiaries of another
       company as well as from other independent businesses. As a result,
       CoreComm has only recently begun to develop the necessary staff to
       effectively manage and operate its businesses and implement its "Smart
       LEC" strategy.

     - Successful Integration of Acquisitions May Not be Realized.   Post-merger
       CoreComm's success in the telecommunications industry depends largely on
       its ability to successfully integrate the businesses that it has acquired
       in the recent past, as well as its ability to integrate the business of
       Voyager and ATX following the mergers.

                                       100
<PAGE>   114

     - Anticipated Benefits May Not be Realized.   The Voyager board of
       directors considered the risk that the anticipated benefits of the
       Voyager merger to Voyager's stockholders may not be realized as a result
       of possible changes in the Internet services and telecommunications
       industry in general, the inability to achieve the anticipated reduction
       in expenses or other potential difficulties in integrating the two
       companies.

     - Significant Costs Involved.   The Voyager board of directors considered
       the significant costs involved in connection with completing the Voyager
       merger and the ATX merger and the substantial management time and effort
       required to complete the Voyager merger and the ATX merger.

     The Voyager board of directors was aware of the potential benefits to the
members of Voyager's management and the Voyager board of directors, discussed
below in "Interests of Certain Persons In the Merger -- Voyager Affiliates,"
including the acceleration of certain options to acquire shares of Voyager
common stock; agreements by certain officers and directors to enter into revised
promissory notes related to outstanding loans owed to Voyager by those persons;
and the provisions granting indemnification and directors' insurance to the
directors of Voyager for actions and omissions of such person occurring prior to
the effective time of the Voyager merger. The Voyager board of directors
determined that these potential benefits were such that they would not affect
the ability of the members of the Voyager board of directors to discharge their
duties.

     In view of the wide variety of factors considered by the Voyager board of
directors, the Voyager board of directors did not find it practicable to, and
did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered. The Voyager board of directors viewed its position
and recommendation as being based on the totality of the information presented
to and considered by it. After taking into consideration all the factors set
forth above, the Voyager board of directors determined that the potential
benefits of the proposed Voyager merger outweighed the potential detriments
associated with the proposed Voyager merger.

THE OPINION OF GOLDMAN SACHS

     Opinion of Goldman Sachs to CoreComm in the Voyager Transaction.   Goldman
Sachs has delivered its written opinion, dated March 12, 2000, to the board of
directors of CoreComm that, as of that date, the stock consideration and the
cash consideration, in the aggregate, to be exchanged under the Voyager merger
agreement was fair from a financial point of view to CoreComm.

     THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED MARCH 12, 2000,
WHICH IDENTIFIES ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE
REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX F AND IS
INCORPORATED BY REFERENCE IN THIS JOINT PROXY STATEMENT AND PROSPECTUS.
SHAREHOLDERS OF CORECOMM ARE URGED TO, AND SHOULD, READ THIS OPINION IN ITS
ENTIRETY.

                                       101
<PAGE>   115

     In connection with its opinion, Goldman Sachs reviewed, among other things:

     - the Voyager merger agreement,

     - the annual reports to shareholders and annual reports on Form 10-K of
       CoreComm for the year ended December 31, 1998,

     - registration statement on Form S-1 of Voyager relating to the initial
       public offering of Voyager,

     - interim reports to stockholders and Quarterly Reports on Form 10-Q of
       CoreComm and Voyager,

     - other communications from CoreComm and Voyager to their respective
       stockholders,

     - internal financial analyses and forecasts for CoreComm prepared by the
       management of CoreComm,

     - internal financial analyses and forecasts for Voyager prepared by the
       management of Voyager and approved for use in its analyses by the
       management of CoreComm, referred to as the Voyager forecasts, and

     - estimates of operating synergies projected by the management of CoreComm
       to result from the Voyager merger, referred to as the Synergies.

     Goldman Sachs also held discussions with members of the senior managements
of Corecomm and Voyager regarding the past and current business operations,
financial condition, and future prospects of their respective companies. In
addition, Goldman Sachs:

     - reviewed the reported price and trading activity for the CoreComm and
       Voyager common stock and relied upon the various valuation analyses for
       CoreComm that it had previously prepared in connection with the ATX
       merger,

     - compared financial and stock market information for CoreComm and Voyager
       with similar information for selected other companies the securities of
       which are publicly traded, and

     - reviewed the financial terms of recent business combinations and
       performed such other studies and analyses as it considered appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of rendering its opinion. Goldman Sachs assumed with
CoreComm's consent that the Voyager forecasts and synergies had been reasonably
prepared and reflected the best currently available estimates and judgments of
CoreComm. In addition, Goldman Sachs did not make an independent evaluation or
appraisal of the assets and liabilities of CoreComm or Voyager or any of their
respective subsidiaries and Goldman Sachs has not been furnished with any such
evaluation or appraisal. The opinion of Goldman Sachs was provided for the
information and assistance of the board of directors of CoreComm in connection
with its consideration of the transaction contemplated by the Voyager

                                       102
<PAGE>   116

merger agreement and this opinion does not constitute a recommendation as to how
any holder of CoreComm shares should vote with respect to the transaction.

     CoreComm and Voyager did not impose any material limitations on Goldman
Sachs in performing its financial analyses and investigations.

     The following is a summary of the material financial analyses used by
Goldman Sachs in connection with providing its written opinion, dated March 12,
2000, to CoreComm's board of directors.

     THE FOLLOWING SUMMARIES OF FINANCIAL ANALYSES INCLUDE INFORMATION PRESENTED
IN TABULAR FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT OF EACH
SUMMARY.

     Historical Stock Trading Analysis.   Goldman Sachs reviewed the historical
trading performance of the CoreComm and Voyager common stock and a composite
index comprised of certain publicly traded Internet service providers and the
S&P 500 for the period from March 3, 1999 to March 3, 2000. The Internet service
provider composite index consisted of America Online, Inc., EarthLink Network,
Inc., Flashnet Communications, Inc., Internet America, Inc., Juno Online
Services, Inc., NetZero, Inc. and OneMain.com, Inc. These companies were chosen
because they are publicly-traded companies with operations that for purposes of
analysis may be considered similar to Voyager. These analyses indicated that the
CoreComm common stock outperformed Voyager, the Internet service provider
composite and the S&P 500, while Voyager underperformed CoreComm, generally
outperformed the Internet service provider composite and generally
underperformed the S&P 500 during the period of time analyzed.

     Selected Companies Analysis.   Goldman Sachs reviewed and compared certain
financial information relating to CoreComm and Voyager to corresponding
financial information, ratios and public market multiples for the following
publicly traded corporations in the Internet service provider industry:

     - America Online, Inc.

     - EarthLink Network, Inc.

     - Flashnet Communications, Inc.

     - Internet America, Inc.

     - Juno Online Services, Inc.

     - NetZero, Inc.

     - OneMain.com, Inc.

     The selected companies were chosen because they are publicly traded
companies with operations that for purposes of analysis may be considered
similar to Voyager.

     Goldman Sachs also calculated and compared various financial multiples and
ratios based on information it obtained from SEC filings, Goldman Sachs Equity
Research estimates, other equity research estimates and other publicly available
data. The multiples and ratios for CoreComm and Voyager were calculated using
their respective

                                       103
<PAGE>   117

common stock closing prices on March 7, 2000. The multiples and ratios for
CoreComm and Voyager were based on information provided by their respective
management and publicly available data. The multiples and ratios for each of the
selected comparable Internet service providers were based on the most recent
publicly available information. Goldman Sachs' analyses of the selected
companies compared the following to the results for CoreComm and Voyager:

     - levered market capitalization as a multiple of estimated 2000 revenue,

     - levered market capitalization as a multiple of estimated 2001 EBITDA,

     - levered market capitalization as a multiple of estimated 1999
       subscribers, and

     - levered market capitalization as a multiple of estimated 2000
       subscribers.

     The results of these analyses are summarized as follows:

     Discounted Cash Flow Analysis.   Goldman Sachs performed a discounted cash
flow analysis of Voyager on a standalone basis, as well as considering the
estimated potential benefits of the combination of Voyager and CoreComm, based
upon forecasts provided by Voyager management and approved for use in connection
with the opinion by the management of CoreComm. Goldman Sachs calculated a range
of per share values for the common stock based on the sum of (i) the discounted
present value of the five-year (2000-2004) stream of projected after-tax cash
flows of Voyager, using discount rates ranging from 14% to 18%; and (ii) the
present value of Voyager of the terminal value of Voyager in 2004, assuming an
EBITDA exit multiple range between 8.0x and 12.0x. The above financial
sensitivity analysis yielded per share values as of January 1, 2000 ranging from
$15.19 to $25.20 on a stand alone basis, and $32.97 to $56.77 when considering
the estimated potential benefits of the Voyager merger.

     Goldman Sachs also examined the sensitivity of the discounted cash flow
value of Voyager to changes in operating assumptions. Using for illustration
purposes a weighted average cost of capital, or WACC, discount rate of 15% and
an EBITDA exit multiple of 11.0x, Goldman Sachs calculated the per share value
of Voyager common stock, on

                                       104

both a stand alone basis and considering the estimated potential benefits of the
combination, assuming the increase or decrease in revenues and basis change in
EBITDA margin. The results of these analyses are as follows:

     Pro Forma Merger Analysis.   Goldman Sachs prepared pro forma analyses of
the financial impact of the merger using discounted cash flows estimates for the
five year period of 2000-2004 for CoreComm and Voyager prepared by their
respective managements. For each of the years 2000 through 2004, Goldman Sachs
assumed merger consideration to be comprised of 81% stock and 19% cash and a
share price of $17.00 per share of Voyager common stock. Based on such analyses,
the proposed transaction would be highly accretive to CoreComm stockholders on
an earnings per share basis in the years 2000 through 2004, considering the
estimated potential benefits of the combination and slightly dilutive to
CoreComm shareholders on an earnings per share basis in the years 2000 through
2004, on a stand alone basis.

     Pro Forma Contribution Analysis.   Goldman Sachs reviewed selected
estimated future operating and financial information for CoreComm, Voyager and
the combined company on a stand alone basis resulting from the merger based on
their respective managements' financial forecasts. Goldman Sachs also analyzed
the relative income statement contribution of CoreComm and Voyager to the
combined company, before taking into account any of the possible benefits that
may be realized following the Voyager merger, based upon estimated results for
the years 1999 through 2004.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
CoreComm or Voyager, or the contemplated transaction.

     The analyses were prepared solely for purposes of Goldman Sachs' providing
its opinion to the CoreComm board of directors as to the fairness from a
financial point of view to CoreComm of the cash consideration and the stock
consideration, in the aggregate, to be exchanged under the Voyager merger
agreement. These analyses do not purport to be appraisals or necessarily reflect
the prices at which businesses or securities actually may be sold. Analyses
based upon forecasts of future results are not necessarily indicative of actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Because these analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of CoreComm, Voyager, Goldman Sachs or any other
person assumes responsibility if future results are materially different from
those forecast.

     As described above, Goldman Sachs' opinion to the board of directors of
CoreComm was one of many factors taken into consideration by the CoreComm board
of directors in making its determination to approve the merger agreement. The
foregoing is a summary of the material financial analyses used by Goldman Sachs
in connection with providing its opinion but it does not purport to be a
complete description of the analyses performed by Goldman Sachs.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and
                                       106
<PAGE>   120

acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements, and
valuations for estate, corporate and other purposes. Goldman Sachs is familiar
with CoreComm having provided investment banking services in conjunction with
the acquisition of ATX and having been retained to undertake a study to render
their opinion in connection with the transactions contemplated by the Voyager
merger agreement.

     Goldman Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to
time effect transactions and hold positions in the securities or options on
securities of CoreComm for its own account and for the account of customers.

     Under a letter agreement dated February 9, 2000, CoreComm exclusively
engaged Goldman Sachs to undertake a study to render an opinion as to the
fairness to CoreComm of the possible acquisition of all or a portion of the
stock or assets of Voyager. Under the terms of this engagement letter, CoreComm
has agreed to pay Goldman Sachs a fee of $2,000,000 in cash for its services
upon consummation of such acquisition.

     CoreComm also has agreed to reimburse Goldman Sachs for its reasonable
out-of-pocket expenses, including attorneys' fees, and to indemnify Goldman
Sachs against certain liabilities, including certain liabilities under the
federal securities laws.

THE OPINION OF MORGAN STANLEY

     Under a letter agreement dated as of December 21, 1999, Morgan Stanley was
engaged to provide financial advisory services to Voyager. Morgan Stanley was
selected by the Voyager board to act as its financial advisor for the Voyager
merger based on Morgan Stanley's qualifications, expertise and reputation, as
well as its knowledge of the business and affairs of Voyager. On March 12, 2000,
Morgan Stanley delivered its oral opinion to the Voyager board that, as of this
date, the consideration to be received by the holders of shares of common stock
under the Voyager merger agreement was fair from a financial point of view to
the Voyager stockholders. Morgan Stanley later confirmed its oral opinion in
writing by delivery of its written opinion dated March 12, 2000, which stated
the considerations and assumptions upon which Morgan Stanley's opinion was
based.

     THE FULL TEXT OF THE OPINION DATED MARCH 12, 2000, WHICH SETS FORTH
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE
SCOPE OF THE REVIEW UNDERTAKEN BY MORGAN STANLEY IN RENDERING ITS OPINION, IS
ATTACHED AS ANNEX E TO THIS JOINT PROXY STATEMENT AND PROSPECTUS. VOYAGER
STOCKHOLDERS ARE URGED TO READ THE ENTIRE OPINION CAREFULLY. MORGAN STANLEY'S
WRITTEN OPINION IS DIRECTED TO THE VOYAGER BOARD AND ONLY ADDRESSES THE FAIRNESS

VOYAGER SPECIAL MEETING. THIS SUMMARY OF THE OPINION IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE OPINION'S FULL TEXT.

     In arriving at Morgan Stanley's written opinion, Morgan Stanley, among
other things:

     - reviewed publicly available financial statements and other information of
       Voyager and CoreComm;

     - reviewed internal financial statements and other financial and operating
       data concerning Voyager, CoreComm, and ATX prepared by the managements of
       Voyager, CoreComm, and ATX, respectively;

     - reviewed financial projections prepared by the managements of Voyager,
       CoreComm, and ATX, respectively;

     - discussed the past and current operations and financial condition and the
       prospects of Voyager, including information relating to the strategic,
       financial and operational benefits anticipated from the Voyager merger
       with senior executives of Voyager;

     - discussed the past and current operations and financial condition and the
       prospects of CoreComm, including information relating to the strategic,
       financial and operational benefits anticipated from the Voyager merger
       and the ATX merger, with senior executives of CoreComm;

     - discussed the past and current operations and financial condition and the
       prospects of ATX, including information relating to the strategic,
       financial and operational benefits anticipated from the ATX merger, with
       senior executives of ATX and CoreComm;

     - reviewed the pro forma impact of the Voyager merger and the ATX merger on
       CoreComm's consolidated capitalization and financial ratios;

     - reviewed the reported prices and trading activity for the Voyager common
       stock and the CoreComm common shares;

     - compared the financial performance of Voyager, CoreComm, and ATX and the
       prices and trading activity of the Voyager common stock and the CoreComm
       common shares with those of other comparable publicly-traded companies
       and their securities;

     - participated in discussions and negotiations among representatives of
       Voyager, CoreComm and their legal advisors;

     - reviewed the Voyager merger agreement, the ATX merger agreement and
       related documents; and

     - performed other analyses and considered other factors that Morgan Stanley
       considered to be appropriate.

     In rendering its opinion, Morgan Stanley assumed and relied upon without
independent verification the accuracy and completeness of the information
reviewed by

                                       108
<PAGE>   122

Morgan Stanley for the purposes of its opinion. Morgan Stanley relied upon the
assessment of the managements of Voyager, CoreComm, and ATX of their ability to
retain key employees of their respective companies. With respect to the
financial projections, including information relating to certain strategic,
financial and operational benefits anticipated from the Voyager merger and the
ATX merger, Morgan Stanley assumed they were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the future
financial performance of Voyager, CoreComm, and ATX. In addition, Morgan Stanley
assumed the Voyager merger will be completed in accordance with the terms set
forth in the Voyager merger agreement, including that the Voyager merger will be
treated as a tax-free reorganization and/or exchange pursuant to the Internal
Revenue Code of 1986. Morgan Stanley has not made any independent valuation or
appraisal of the assets or liabilities of Voyager, CoreComm, or ATX, nor was
Morgan Stanley furnished with any such appraisals. Morgan Stanley's opinion is
necessarily based on financial, economic, market and other conditions as in
effect on, and the information made available to it as of, the date of this
document.

     The following is a brief summary of the material financial analyses
performed by Morgan Stanley in connection with its oral opinion and the
preparation of its opinion letter dated March 12, 2000. Certain of these
summaries of financial analyses include information presented in tabular format.
In order to fully understand the financial analyses used by Morgan Stanley, the
tables must be read together with the text of each summary. The tables alone do
not constitute a complete description of the financial analyses.

     Historical Public Market Trading Value.   Morgan Stanley reviewed the
recent stock price performance of Voyager based on an analysis of the historical
closing prices and trading volumes from July 21, 1999, the date of Voyager's
initial public offering, through March 10, 2000. The following table lists the
average daily closing prices of shares of Voyager common stock for the periods
indicated. Morgan Stanley then compared the CoreComm offer price of
approximately $17.00, based on the closing price of the CoreComm common shares
on March 10, 2000, to the average Voyager closing prices over this period.

     Comparative Stock Price Performance.   As part of its analysis, Morgan
Stanley compared the stock price performance of the Voyager common stock from
July 21, 1999 through March 10, 2000 with that of the Nasdaq Composite Index and
a group of

                                       109

selected domestic Internet service providers and the stock price performance of
the CoreComm common shares from March 10, 1999 through March 10, 2000 with that
of the Nasdaq Composite Index and a group of selected competitive local exchange
carriers.

     The group of selected domestic Internet service providers forming Voyager's
peer group included EarthLink Network, Inc., Prodigy Communications Corporation,
OneMain.Com, Inc. and Internet America, Inc. The group of selected competitive
local exchange carriers forming CoreComm's peer group included Allegiance
Telecom, Inc., Focal Communications Corporation, MGC Communications, Inc. and US
LEC Corp.

     Morgan Stanley observed that over the specified periods the closing market
prices appreciated as set forth below:

     Comparable Companies Analysis.   Using closing market prices on March 10,
2000, Morgan Stanley calculated aggregate value, defined as equity value
adjusted for capital structure, to revenue multiples for Voyager for calendar
years 2000 and 2001 and subscriber multiples for Voyager at the end of calendar
years 1999 through 2001, based on estimates developed by Voyager's management.
Morgan Stanley then compared the revenue and subscriber multiples obtained for
Voyager with multiples obtained for the Voyager peer group based on publicly
available research estimates. Morgan Stanley calculated aggregate value to
calendar year 1999 gross property, plant and equipment multiples and aggregate
value to revenue multiples for calendar years 1999 and 2000 for CoreComm based
on estimates developed by CoreComm's management. Morgan Stanley then compared
the gross property, plant and equipment and revenue multiples for CoreComm with
multiples obtained for the CoreComm peer group based on publicly available
research estimates. In addition, Morgan Stanley calculated aggregate value to
calendar year-end 1999 gross property, plant and equipment multiples and
aggregate value to revenue multiples for calendar years 1999 and 2000 for ATX,
CoreComm's pending merger partner, based on estimates developed by ATX's
management. Morgan Stanley then compared the gross property, plant and equipment
and revenue multiples for ATX with multiples obtained for a group of selected
peer companies based on publicly available research estimates. The group of
selected companies forming ATX's peer group included ITC DeltaCom, Inc., Network
Plus Corp., CTC Communications

     Morgan Stanley noted that CoreComm's offer price based on the closing price
of CoreComm common shares on March 10, 2000 represented a multiple of 5.8x
Voyager's calendar year 2000 revenue and 3.6x Voyager's calendar year 2001
revenue.

     No company used in the peer group comparison is identical to Voyager,
CoreComm or ATX. In evaluating the peer group companies, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of Voyager, CoreComm and ATX, such as the impact of
competition on Voyager, CoreComm and ATX and the industry generally, industry
growth and the absence of any material adverse change in the financial condition
and prospects of Voyager, CoreComm and ATX or the industry or in the financial
markets in general. Mathematical analysis, such as determining the average or
median, is not in itself a meaningful method of using peer group data.

     Securities Research Analysts' Future Price Targets Analysis.   Morgan
Stanley reviewed the 12-month price targets for the shares of the Voyager common
stock as

                                       111
<PAGE>   125

projected by analysts from various financial institutions in recent reports.
These targets reflected each analyst's estimate of the future public market
trading price of the Voyager common stock at the end of the particular period
considered for each estimate. Morgan Stanley then arrived at the present value
for these targets using an estimated equity discount rate of 14.8% for the
Voyager common stock.

     This analysis supported the following mean and median values for the
Voyager common stock:

     Discounted Cash Flow Analysis.   Morgan Stanley performed a discounted cash
flow analysis, which considers the present value of projected cash flows using
discount rates and terminal year EBITDA multiples as indicated below, of
Voyager's business. Morgan Stanley analyzed Voyager's business using a forecast
for the period beginning January 1, 2000 and ending December 31, 2004, based on
estimates developed by Voyager's management. Morgan Stanley estimated Voyager's
discounted cash flow value by using a discount rate range of 13.5% to 14.5% and
terminal multiples of estimated 2004 EBITDA ranging from 7.0x to 9.0x. This
analysis yielded a range of values for the Voyager common stock of approximately
$12 per share to $17 per share. CoreComm's offer price of approximately $17,
based on the closing price of CoreComm common shares on March 10, 2000,
represented a premium to the discounted cash flow values of 0% to 42%.

     Morgan Stanley also performed a discounted cash flow analysis of CoreComm's
business. Morgan Stanley analyzed CoreComm's business using a forecast for the
period beginning January 1, 2000 and ending December 31, 2005, based on
estimates developed by CoreComm's management. Morgan Stanley estimated
CoreComm's discounted cash flow value by using a discount rate of 17.5% and
terminal multiples of estimated 2004 EBITDA ranging from 9.0x to 11.0x. This
analysis yielded a range of values for CoreComm common shares of approximately
$63 per share to $78 per share. Morgan Stanley noted that the public market
trading price for the CoreComm common stock as of March 10, 2000 was $47.88. The
discounted cash flow value of the CoreComm common stock represented a premium to
the public market trading value of CoreComm common shares of 32% to 63%. In
addition, Morgan Stanley performed a discounted cash flow analysis of ATX's
business. Morgan Stanley analyzed ATX's business using a forecast for the period
beginning January 1, 2000 and ending December 31, 2004, based on estimates
developed by ATX's management. Morgan Stanley estimated ATX's discounted cash
flow value by using a discount rate of 17.5% and terminal multiples of estimated
2004 EBITDA ranging from 9.0x to 11.0x. This analysis yielded a range of values
for ATX of approximately $722 million to $871 million.

     Morgan Stanley performed a variety of financial and comparative analyses
solely for purposes of providing its opinion to the Voyager board as to the
fairness from a financial point of view to the Voyager stockholders of the
merger consideration.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, selecting any portion of its analyses, without
considering all analyses, would create an incomplete view of the process
underlying its opinion. In addition, Morgan Stanley may have given various
analyses and factors more or less weight than other analyses and factors, and
may have considered various assumptions more or less probable than other
assumptions, so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be Morgan Stanley's view of the
actual value of Voyager, CoreComm or ATX.

     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Voyager, CoreComm or ATX.
The analyses performed by Morgan Stanley are not necessarily indicative of
future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates. The analyses performed were
prepared solely as part of Morgan Stanley's analysis of the fairness of the
merger consideration from a financial point of view to the Voyager stockholders
and were conducted in connection with the delivery of its opinion to the Voyager
board. The analyses are not intended to be appraisals or to reflect the prices
at which Voyager, CoreComm or ATX might actually be sold or the price at which
their securities may trade.

     The merger consideration was determined through arm's-length negotiations
between Voyager and CoreComm and was approved by the Voyager board. Morgan
Stanley did not recommend any specific merger consideration to Voyager or that
any specific merger consideration constituted the only appropriate merger
consideration for the merger. Morgan Stanley's opinion to the Voyager board was
one of many factors taken into consideration by the Voyager board in making its
determination to approve the Voyager merger. Consequently, the Morgan Stanley
analyses described above should not be viewed as determinative of the opinion of
the Voyager board with respect to the value of Voyager or whether the Voyager
board would have been willing to agree to different merger consideration.

     Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking business, is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. In the ordinary course of
Morgan Stanley's trading, brokerage and financing activities, Morgan Stanley or
its affiliates may at any time hold long or short positions, may trade,

make a market or otherwise effect transactions, for its own account or for the
accounts of customers, in the securities of Voyager, CoreComm and ATX.

     Under the letter agreement dated as of December 21, 1999, Morgan Stanley
has provided advisory services and a financial opinion in connection with the
merger and Voyager has agreed to pay a fee of approximately $5.0 million to
Morgan Stanley based on the aggregate value of the transaction if the Voyager
merger is consummated. In addition, Voyager has also agreed to indemnify Morgan
Stanley and its affiliates, their respective directors, officers, agents and
employees and each person, if any, controlling Morgan Stanley or any of its
affiliates against specified liabilities and expenses, including the fees of its
legal counsel and specified liabilities under the federal securities laws,
arising out of Morgan Stanley's engagement and the transactions in connection
with their engagement.

INTERESTS OF CERTAIN PARTIES IN THE MERGER -- VOYAGER AFFILIATES

     Treatment of Options Granted Under Voyager's Stock Option Plan.   Voyager's
stock option plan provides for acceleration of unvested shares in the event of a
change of control of Voyager. Accordingly, unvested options granted under
Voyager's stock option plan to officers and directors of Voyager will vest upon
completion of the Voyager merger.

     Voyager Employment Agreements.   CoreComm has agreed to honor all
obligations under the terms of the employment agreements to which Voyager or any
of its subsidiaries is presently a party.

     Registration Rights Agreement.   Upon consummation of the Voyager merger,
certain principal stockholders of Voyager, including certain officers and
directors, will enter into a registration rights agreement pursuant to which
these principal stockholders will have the right to demand that post-merger
CoreComm, at any time on or after six months from the date of the closing of the
Voyager merger, register all or part of their registrable shares of common
stock, provided that post-merger CoreComm is not required to effect more than
one registration. In addition, these principal stockholders may participate, or
"piggy-back" in equity offerings initiated by post-merger CoreComm that are
registered under the Securities Act of 1934, subject to, the approval of the
underwriters involved with any such equity offering and other customary terms
and conditions.

     Indemnification and Insurance.   Under the Voyager merger agreement,
post-merger CoreComm will preserve all rights to indemnification existing as of
March 12, 2000 in favor of any current or former director, officer, or employee
of Voyager for a period of at least six years following the Voyager merger.
Post-merger CoreComm will also indemnify directors, officers, agents and
employees of Voyager against liabilities or claims arising before the Voyager
merger is completed and as a result of their positions with Voyager. Finally,
post-merger CoreComm will pay the applicable person's legal and other expenses
in connection with any proceeding arising out of any matter occurring until the
Voyager merger is completed.

                                       114
<PAGE>   128

     Prior to the effective time of the Voyager merger, CoreComm will purchase,
subject to limitations as to cost, an extended reporting period endorsement
under Voyager's existing directors' and officers' liability insurance coverage
for Voyager's directors and officers which shall provide Voyager's directors and
officers with coverage at least as favorable as the current policy for six years
following the Voyager merger. It is anticipated that the total aggregate cost of
such coverage will be approximately $750,000.

     Certain Indebtedness of Voyager Affiliates.   In connection with the
execution of the Voyager merger agreement, certain executive officers and a
director agreed to revise the terms of certain outstanding promissory notes
which each such person had issued in favor of Voyager.

     - Voyager had previously made two loans, evidenced by promissory notes, to
       Christopher Torto, its Chief Executive Officer and President. In April
       1999, Voyager made a loan in the principal amount of $0.5 million to Mr.
       Torto which is payable over three years and in July 1999, Voyager made a
       loan in the principal amount of $5.0 million which is payable over four
       years. Mr. Torto executed a side agreement with CoreComm in which Mr.
       Torto agreed to enter into revised notes effective as of the closing of
       the Voyager merger. In the side letter, Mr. Torto agreed to pay 25% of
       the principal due on the promissory notes at the closing of the Voyager
       merger with the remainder of the principal and interest due two years
       from the closing, subject to certain earlier repayment obligations if Mr.
       Torto sells any shares of CoreComm common stock prior to the maturity of
       the revised notes.

     - In January 1999, Voyager made a loan to Mr. Friedly, Chairman of the
       Voyager board of directors, in the principal amount of $4.2 million, in
       connection with the sale of certain Voyager stock to Mr. Friedly. The
       promissory note issued in connection with this loan matures in January
       2003. Mr. Friedly executed a side agreement with CoreComm in which Mr.
       Friedly agreed to enter into a revised note effective as of the closing
       of the Voyager merger. In the side letter, Mr. Friedly agreed to pay 25%
       of the principal due on the promissory note at the closing of the Voyager
       merger with the remainder of the principal and interest due two years
       from the closing, subject to certain earlier repayment obligations if Mr.
       Friedly sells any shares of CoreComm common stock prior to the maturity
       of the revised note.

     - In January 1999, Voyager made a loan to Mr. Osvaldo deFaria, the Chief
       Operating Officer of Voyager, in the principal amount of $1.8 million, in
       connection with the sale of certain Voyager stock to Mr. deFaria. The
       promissory note issued in connection with this loan matures in January
       2003. Mr. deFaria executed a side agreement with CoreComm in which Mr.
       deFaria agreed to enter into a revised note effective as of the closing
       pursuant to which Mr. deFaria agreed to certain earlier repayment
       obligations if Mr. deFaria sells any shares of CoreComm common stock
       prior to the maturity of the revised note.

ACCOUNTING TREATMENT


     For more information regarding the accounting treatment of the Voyager
merger, please refer to the unaudited pro forma financial data of Voyager in the
section of this joint proxy statement and prospectus entitled "More About the
Companies -- Voyager.net, Inc. -- Pro Forma Condensed Consolidated Financial
Statements (Unaudited)."


APPRAISAL RIGHTS

     Under Delaware law, a Voyager stockholder may exercise his, her or its
appraisal rights by delivering to Voyager a demand in writing for the appraisal
of its shares and not voting for or consenting in writing to the Voyager merger
agreement or the Voyager merger. Voyager stockholders considering seeking
appraisal should recognize that the fair value of shares could be determined to
be more than, the same as or less than the value of the Voyager merger
consideration to which stockholders are entitled if they do not exercise their
appraisal rights. Stockholders who elect to exercise appraisal rights must
comply strictly with all of the procedures set forth in Section 262 of the
Delaware General Corporation Law to preserve those rights. We have attached a
copy of Section 262 of the Delaware General Corporation Law, which sets forth
these appraisal rights, as Annex D to this joint proxy statement and prospectus.

     Section 262 of the Delaware General Corporation Law sets forth the required
procedure a stockholder seeking appraisal must follow. Making sure that you
actually perfect your appraisal rights can be complicated. The procedural rules
are specific and must be followed completely. Failure to comply with the
procedure may cause you to lose your appraisal rights. The following is only a
summary of your rights and the procedure relating to appraisal rights and is
qualified in its entirety by the provisions of Section 262 of the Delaware
General Corporation Law. Please review Section 262 for the complete procedure.
Voyager will not give you any notice other than as described in this joint proxy
statement and prospectus and as required by Delaware law.

APPRAISAL RIGHTS PROCEDURES

     If you are a Voyager stockholder and you wish to exercise your appraisal
rights, you must satisfy the following provisions of Section 262 of the Delaware
General Corporation Law. Only a record holder may demand appraisal, and
therefor, if you are the beneficial owner of shares held of record by a broker,
bank or other nominee, you must direct such record owner to comply with the
requirements of the statute.

     - You must make a written demand for appraisal: You must deliver a written
       demand for appraisal to Voyager before the taking of the vote on the
       Voyager merger agreement and the Voyager merger at the special meeting.

     - You must not vote for or consent in writing to the Voyager merger: You
       must not consent to or vote for the Voyager merger or the adoption of the
       Voyager merger agreement. If you vote for or consent by written consent
       to the Voyager merger

                                       116
<PAGE>   130

       agreement and Voyager merger, you will not be entitled to any right to
       seek appraisal.

     - You must continuously hold your Voyager shares: You must continuously
       hold, as a record holder, your shares of Voyager common stock from the
       date you make the demand for appraisal through the completion of the
       Voyager merger. If you are the record holder of Voyager common stock on
       the date you make a written demand for appraisal but then transfer your
       shares before the Voyager merger, you will lose any right to appraisal in
       respect of those shares.

     - You should read the paragraphs below for more details on making a demand
       for appraisal.

     A written demand for appraisal of Voyager common stock must be executed by
or on behalf of a stockholder of record and must reasonably identify the
stockholder and that he, she or it intends to demand appraisal of his, her or
its shares. If you own Voyager common stock in a fiduciary capacity, such as a
trustee, guardian or custodian, the demand for appraisal must be executed by or
for the record owner.

     If you own Voyager common stock with one or more persons, such as in a
joint tenancy or tenancy in common, the demand for appraisal must be executed by
or for all joint owners. An authorized agent, which could include one or more of
the joint owners, may sign the demand for appraisal for a stockholder of record;
however, the agent must expressly disclose who the stockholder of record is and
that the agent is signing the demand as that stockholder's agent.

     If you are a record owner, such as a broker, who holds Voyager common stock
as a nominee for others, you may exercise a right of appraisal with respect to
the shares held for one or more beneficial owners, while not exercising such
right for other beneficial owners. In such a case, you should specify in the
written demand the number of shares as to which you wish to demand appraisal. If
you do not expressly specify the number of shares, we will assume that your
written demand covers all the shares of Voyager common stock that are in your
name.

     If you are a Voyager stockholder who elects to exercise appraisal rights,
you should mail or deliver by hand a written demand to:

              Voyager.net, Inc.
              4660 S. Hagadorn Road, Suite 320
              East Lansing, MI 48823
              Attention: Secretary


     It is important that Voyager receives all written demands before the
stockholder meeting on September 22, 2000. As explained above, this written
demand should be signed by, or on behalf of, the stockholder of record. The
written demand for appraisal should specify the stockholder's name and mailing
address, the number of shares of common stock owned, and that the stockholder is
thereby demanding appraisal of his, her or its shares.


                                       117
<PAGE>   131

     If you fail to comply with any of these conditions and the Voyager merger
becomes effective, you will only be entitled to receive the Voyager merger
consideration provided in the Voyager merger agreement.

     Written Notice.   Within 10 days after the completion of the Voyager
merger, Voyager must give written notice setting forth the date the Voyager
merger has become effective to each stockholder who has fully exercised his, her
or its appraisal rights in full compliance with the conditions of Section 262 of
the Delaware General Corporation Law.

     Petition with the Chancery Court.   Within 120 days after the completion of
the Voyager merger, either Voyager or any stockholder who has complied with the
conditions of Section 262 may file a petition for appraisal in the Delaware
Chancery Court demanding that the Chancery Court determine the value of the
shares of Voyager stock held by all of the stockholders who are entitled to
appraisal rights. Voyager has no present intention of filing an appraisal
petition. Accordingly, if you intend to preserve your rights of appraisal, you
should file a petition in the Delaware Court of Chancery. Because Voyager has no
obligation to file a petition, if no stockholder files a petition within 120
days after the completion of the Voyager merger, you will lose your rights of
appraisal.

     Withdrawal of Demand.   If you change your mind and decide you no longer
want to assert appraisal rights, you may withdraw your demand for appraisal
rights at any time within 60 days after the closing of the Voyager merger. You
may also withdraw your demand for appraisal rights after 60 days after the
closing of the Voyager merger, but only with the written consent of Voyager.
Once a petition for appraisal has been filed with the Delaware Court of
Chancery, such proceeding may not be discussed as to any stockholder without
approval of the court. If you effectively withdraw your demand for appraisal
rights, you will receive the merger consideration provided in the Voyager merger
agreement.

     Request for Appraisal Rights Statement.   If you have complied with the
conditions of Section 262, you are entitled to receive a statement from Voyager
which sets forth the number of shares held by stockholders who have demanded
appraisal rights, and the number of stockholders who own those shares. To
receive this statement, you must send a written request to Voyager within 120
days after the completion of the Voyager merger. Voyager has 10 days after
receiving a request to mail you the statement.

     Chancery Court Procedures.   If you properly file a petition for appraisal
in the Delaware Chancery Court, Voyager will then have 20 days after service of
a copy of the petition is made on it to provide the Chancery Court with a list
of the names and addresses of all stockholders who have demanded appraisal
rights and have not reached an agreement with Voyager as to the value of their
shares. At a hearing on the petition, the Chancery Court will determine which
stockholders, if any, have fully complied with Section 262 of the Delaware
General Corporation Law and whether they are entitled to appraisal rights under
Section 262. The Chancery Court may also require you to submit your stock
certificates to the Register in Chancery so that it can note on the certificates

                                       118
<PAGE>   132

that an appraisal proceeding is pending. If you do not follow the Chancery
Court's directions, you may be dismissed from the proceeding.

     Appraisal of Shares.   After the Chancery Court determines which
stockholders are entitled to appraisal rights, it shall determine the fair value
of your shares exclusive of any value arising from the expectation or
accomplishment of the Voyager merger. After the Chancery Court determines the
fair value of their shares, it will direct Voyager to pay that value to the
stockholders who qualified to have their shares appraised. The Chancery Court
can also direct Voyager to pay interest, simple or compound, on that value if
the Chancery Court determines that interest is appropriate. In order to receive
your payment for your shares, you must then surrender your stock certificates to
Voyager.

     The Chancery Court could determine that the fair value of shares of stock
is more than, the same as or less than the merger consideration. You should also
be aware that an opinion of an investment banking firm that the Voyager merger
is fair is not an opinion of an investment banking firm that the merger
consideration constitutes fair value under Section 262.

     Costs and Expenses of Appraisal Proceeding.   The costs of the appraisal
proceeding may be assessed against Voyager and/or the stockholders participating
in the appraisal proceeding, as the Chancery Court deems equitable under the
circumstances. You may also request that the Chancery Court allocate the
expenses of the appraisal action incurred by any stockholder pro rata against
the value of all of the shares entitled to appraisal.

     Loss of Stockholder's Rights.   If you demand appraisal rights, after the
completion of the Voyager merger you will not be entitled to:

     - vote shares of stock, for any purpose, for which you have demanded
       appraisal rights;

     - receive payment of dividends or any other distribution with respect to
       such shares, except for dividends or distributions, if any, that are
       payable to holders of record as of a record date prior to the effective
       time of the Voyager merger; or

     - receive the payment of the consideration provided for in the Voyager
       merger agreement, unless you properly withdraw your demand for appraisal.

     If you fail to comply strictly with the procedures described above you will
lose your appraisal rights. Consequently, if you wish to exercise your appraisal
rights, we strongly urge you to consult a legal advisor.

                      THE MERGER BETWEEN CORECOMM AND ATX

BACKGROUND OF THE MERGER BETWEEN CORECOMM AND ATX

     On December 9, 1999, Michael Peterson of CoreComm was contacted by Louis
Friedman, a Managing Director at Donaldson, Lufkin & Jenrette Securities
Corporation. Mr. Friedman informed Mr. Peterson that DLJ had been engaged by ATX
to assist it in considering various strategic alternatives, including a possible
sale of ATX, and inquired whether CoreComm would be interested in receiving a
confidential information memorandum prepared by DLJ concerning ATX with a view
towards participating in a transaction with ATX. Mr. Peterson indicated that
CoreComm would be interested in receiving the confidential information
memorandum.

     On December 15, 1999, CoreComm executed a confidentiality agreement and was
given a copy of the confidential information memorandum. The confidential
information memorandum provided a detailed summary of ATX's corporate structure,
business and projections and was intended to solicit interest in a business
combination transaction. CoreComm was informed by DLJ that various other
interested parties selected by DLJ had also received a copy of the confidential
information memorandum and that following a review of such materials, all
interested parties would be requested to submit a nonbinding indication of
interest, which should include, among other things, the form of a proposed
transaction, the form of consideration and a valuation range for ATX. CoreComm
was informed that based on these nonbinding indications of interest, parties
selected by DLJ and ATX would be invited to participate in a second phase which
would include management presentations, tours of facilities, access to a data
room and other due diligence procedures. DLJ informed CoreComm that the deadline
for receipt of indications of interest was 12:00 noon on January 7, 2000.

     Over the next three weeks, members of CoreComm management reviewed the
materials that had been supplied. During this same period, representatives of
CoreComm also spoke to representatives of DLJ in order to obtain certain
clarifications and supplemental information.

     On December 28, 1999, Goldman, Sachs & Co. was engaged by CoreComm to act
as its financial advisor and to undertake a study to enable it to render an
opinion in connection with the possible acquisition of all or a portion of the
equity interest or assets of ATX.

     On January 7, 2000, Michael Peterson met with Thomas Gravina, who was at
that time Co-Chief Executive Officer of ATX and James Broner of DLJ to discuss
in more detail the business and operations of ATX and CoreComm. Later that same
day, CoreComm submitted a formal indication of interest. At that time, the
proposal contemplated the purchase of substantially all the stock or assets of
ATX by way of purchase or merger and assumed an estimation of valuation of ATX
between $700.0 million and $900.0 million. The indication of interest further
stated that any transaction would be subject to valuation adjustments depending
on:

     - ATX's debt and other noncurrent liabilities;

                                       120
<PAGE>   134

     - working capital adjustments; and

     - capital expenditures amounts.

     At a regularly scheduled meeting of the CoreComm board of directors held on
January 18, 2000, the CoreComm board of directors reviewed for the first time in
a preliminary fashion the potential transaction with ATX. At that time the board
of directors authorized CoreComm to continue to review a potential transaction
with ATX.

     On January 19, 2000, the management of ATX conducted a presentation for
representatives of CoreComm's senior management at ATX's executive offices in
Bala Cynwyd, Pennsylvania, a suburb of Philadelphia. Attending on behalf of
CoreComm were Patty Flynt, Chief Operating Officer, Mr. Peterson and other
representatives of CoreComm. In addition, CoreComm was accompanied by
representatives of Goldman Sachs. All of ATX's senior management, including Mr.
Gravina and Debra Buruchian, the other Co-Chief Executive Officer at that time,
Tim Allen, Vice President of Sales and Marketing, and Jeffrey Coursen, Vice
President of Strategic Development, were present, as were representatives of
DLJ.

     On January 24 and January 25, 2000, counsel to CoreComm conducted legal due
diligence in a data room at ATX's headquarters in Bala Cynwyd, Pennsylvania. In
addition, Goldman Sachs also conducted its financial due diligence. On those
dates CoreComm simultaneously conducted operational due diligence at the same
location.

     On February 1, 2000, a meeting was held at ATX's headquarters in Bala
Cynwyd, Pennsylvania. This meeting was attended by Barclay Knapp, the President,
Chief Executive Officer and Chief Financial Officer of CoreComm, Mr. Peterson,
Mr. Gravina, Michael Karp (ATX's then principal partner and current principal
stockholder) and a representative of DLJ. The purpose for these discussions was
for the parties to further familiarize themselves with each other and to further
assess the interest of the parties in pursuing a business combination
transaction.

     On February 3, 2000, DLJ informed CoreComm that it was invited to submit a
definitive proposal to ATX as part of the process DLJ was conducting on behalf
of ATX. CoreComm was informed that all definitive proposals had to be received
by Tuesday, February 22, 2000. The invitation was accompanied by a draft merger
agreement prepared by ATX's outside counsel. CoreComm was asked to mark up the
agreement, provide clear descriptions of its contemplated structure for the
transaction, clearly state the valuation and the form of consideration in a
transaction, as well as provide other customary terms to be included in a
proposal.

     Between February 3, 2000 and February 22, 2000, on a number of occasions
representatives of CoreComm met and/or had discussions with representatives of
ATX, DLJ and Goldman Sachs in order for both parties to obtain additional
information about each other (including information that CoreComm desired to
have in order to prepare its definitive proposal) and for both parties to
conduct operational due diligence.

     On February 22, 2000, CoreComm submitted its proposal to DLJ and ATX. That
proposal contemplated a structure substantially in the form being submitted for
approval

                                       121
<PAGE>   135

in this joint proxy statement and prospectus. The proposal assumed an estimated
valuation of ATX at approximately $800.0 million, with valuation adjustments
depending on:

     - debt and other noncurrent liabilities;

     - working capital adjustments; and

     - capital expenditure amounts.

The proposal contemplated the $800.0 million being allocated $80.0 million in
cash, $200.0 million in common stock and $520.0 million in preferred stock.

     On February 23, 2000, DLJ invited CoreComm and its legal and financial
advisers to meet with representatives of ATX and its financial and legal
advisers in order to discuss and resolve outstanding due diligence items. On
February 25, 2000, a meeting was held in the offices of ATX's lawyers.

     During the next week, ATX and CoreComm and their respective advisors
conducted intensive due diligence on the remaining legal and financial issues
and negotiated via conference calls and through the exchange of facsimiles the
underlying documentation and various proposals. The negotiations covered, among
other things, the determination of the total consideration, as well as the mix
among the cash, common stock and convertible preferred stock components.

     On March 2, 2000, CoreComm presented a revised proposal to DLJ. The major
revisions involved increasing the cash portion of the consideration and
adjusting the features of the convertible preferred stock to create more
immediate value for the existing ATX stockholders.

     On March 3, 2000, the parties entered into an exclusivity agreement that
provided that the parties would negotiate exclusively with each other until 9:00
a.m. on Thursday, March 9, 2000.

     On March 3, 2000, the parties orally agreed on a term sheet for the
transaction laying out the total consideration, the mix between the different
components of the consideration, and the general terms of the different
components of the consideration.

     On March 4, 2000, Mr. Gravina and Mr. Knapp discussed issues related to
management roles, incentive plans for management and employees and the future
operations of the combined company. This conversation was a continuation of
discussions Mr. Gravina had with Mr. Peterson throughout the period of
negotiations which continued up until the date of execution of the ATX merger
agreement.

     Beginning on March 6, 2000, and continuing on March 7, 2000,
representatives of the parties met at CoreComm's attorneys' offices in New York
City with a view to negotiating definitive terms for the transaction.
Negotiations centered primarily around the structure of the transaction and
details related to the forms of consideration to be received by the existing ATX
stockholders. In addition, at these meetings CoreComm management indicated for
the first time to ATX and DLJ the potential transaction being negotiated with
Voyager.

                                       122
<PAGE>   136

     On March 7, 2000, CoreComm's board of directors held a special meeting at
which they received a report from Messrs. Peterson and Lubasch as to the status
of the transaction (as well as the Voyager merger). The board of directors
indicated its approval to continue negotiations and finalize documentation for a
definitive agreement in each transaction, subject to final approval by the board
of directors.

     On March 8, 2000, the parties met with their respective lawyers and
advisers in order to review the documentation and the parties agreed to have
their representatives reconvene in New York on March 9, 2000 in order to
finalize the transaction. Also, on March 8, 2000, the parties extended the
exclusivity agreement until 4:30 A.M. on Friday, March 10, 2000.

     On March 9, 2000, the parties again met at CoreComm's attorneys' offices to
finalize documentation and negotiate the remaining open issues.

     Also on March 9, 2000, the CoreComm board of directors held a meeting to
approve the ATX merger agreement and the ATX merger. Representatives of Goldman
Sachs made a presentation regarding its analysis of the financial terms of the
proposed transaction and delivered their oral opinion, which was subsequentially
confirmed in writing that, as of that date, the stock consideration and the cash
consideration, in the aggregate, to be paid by CoreComm under the ATX merger
agreement was fair from a financial point of view to CoreComm.

     Late on the evening of March 9, 2000, the material open issues having been
resolved, documentation was completed and definitive agreements relating to the
ATX merger and the other related transactions were executed. The ATX merger was
announced publicly early on March 10, 2000.

     Beginning in mid-July, CoreComm, ATX and the stockholders of ATX began
discussions to explore the possibility of restructuring the terms of the ATX
merger to increase the portion of the $150 million of cash consideration that
could be paid, at CoreComm's option, in the form of notes, and to make other
changes to the terms of the consideration to be received by the ATX
stockholders. Negotiations continued through July 31, 2000, when the parties
agreed to amend the original ATX merger agreement. The CoreComm board of
directors approved all of the amendments.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF CORECOMM; REASONS FOR THE ATX MERGER

     The board of directors of CoreComm has determined that the ATX merger is
fair and in the best interests of the shareholders of CoreComm and has
unanimously approved and adopted the ATX merger agreement. ACCORDINGLY,
CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE
"FOR" APPROVAL AND ADOPTION OF THE ATX MERGER AGREEMENT.

     In considering the recommendation of the CoreComm board of directors with
respect to the ATX merger, CoreComm shareholders should also consider that some
of

                                       123
<PAGE>   137

the members of the CoreComm board of directors have interests in the merger that
may be different from, or in addition to, the interests of the shareholders of
CoreComm generally. For more information concerning the interests of these
persons in the ATX merger, please refer to the section of this joint proxy and
prospectus entitled "The Merger between CoreComm and ATX -- Interests of Certain
Parties in the Merger -- CoreComm Affiliates."

     In reaching the determination that the ATX merger agreement and the ATX
merger are in the best interests of CoreComm and its shareholders, CoreComm's
board of directors consulted with CoreComm's management, as well as its
financial advisor, legal counsel and accountants and considered the short-term
and long-term interests of CoreComm and other acquisitions available to
CoreComm. The factors considered by CoreComm's board of directors include those
described below. While all of these factors were considered by CoreComm's board
of directors, CoreComm's board of directors did not make determinations with
respect to each of the factors. Rather, CoreComm's board of directors made its
judgment with respect to the ATX merger and the ATX merger agreement based on
the total mix of information available to it, and the judgments of individual
directors may have been influenced to a greater or lesser degree by their
individual views with respect to different factors.

     In particular, the CoreComm board of directors considered the following
material factors, among others, all of which it deemed favorable, in reaching
its decision to approve the ATX merger and the ATX merger agreement:

     - Judgment, advice and analyses of management.   The board of directors
       placed significant reliance on the judgment, advice and analyses of its
       management with respect to the strategic, financial and operational
       benefits of the merger with ATX, based in part on the business,
       financial, accounting and legal due diligence investigations performed
       with respect to ATX.

     - Potential synergies as a result of the ATX merger.   Among other things,
       the combination of ATX and CoreComm should enable post-merger CoreComm to
       extract the better sales practices and superior skills that are currently
       found in their separate sales forces, eliminating those practices and
       skills that are less effective. Growth is anticipated through the
       offering of post-merger CoreComm's residential services in the geographic
       markets currently serviced by ATX, while incorporating ATX's proven
       customer service and retention capabilities. ATX has a customer base
       consisting of approximately 100,000 local access lines and approximately
       320,000 long distance access line equivalents, an asset which potentially
       can be penetrated with CoreComm's services. Specifically, combining with
       ATX should augment CoreComm's penetration of its "Smart LEC" rollout in
       the Eastern U.S. and provide an immediate boost to the increasing
       Internet-centric focus of CoreComm's business. Coupled with general cost
       synergies inherent in combining back-office operations and correlated
       business strategies, the board of directors recognized the potential for
       efficiencies and cost savings.

     - Superior business strategy, capability, market position and growth
       prospects.   The board of directors believes that a business combination
       with ATX will enhance
                                       124
<PAGE>   138

       CoreComm's goal of expansion and the creation of a national
       telecommunications presence. ATX's principal markets, Pennsylvania, New
       Jersey, Delaware, Maryland, the District of Columbia and Virginia, are
       within the geographic areas that were next scheduled to be developed by
       CoreComm. In addition, by combining CoreComm's operations in the Midwest
       with ATX's presence in the Mid-Atlantic, post-merger CoreComm's footprint
       will expand to areas currently occupied by a number of different regional
       Bell operating companies and other competitive local exchange carriers.
       The board of directors believes that the ATX merger would be accretive to
       post-merger CoreComm EBITDA, thus enhancing its cash flow and enabling
       additional expansion with available funds. Furthermore, it is expected
       that post-merger CoreComm will be able to target higher margin
       data-centric business customers than CoreComm does today. Accordingly,
       the potential expanded customer base could combine with enhanced revenues
       per customer (and the reduced churn characteristics ATX brings) to
       provide more rapid growth.

     - The ATX merger agreement.   The express terms and conditions of the ATX
       merger agreement provide an equitable basis to combine the two companies
       from the standpoint of CoreComm. The form of consideration given to ATX
       stockholders potentially was a particularly attractive feature in that a
       significant portion of the consideration was non-cash, in the form of
       post-merger CoreComm common and preferred stock and, potentially, senior
       notes.

     - Advantages of a larger enterprise.   The combination of ATX and CoreComm
       should result in a larger company that should provide post-merger
       CoreComm with more depth to the management team and cost savings in its
       dealings with its vendors, due to the larger volume of business it would
       generate for them.

     - Improved cash flow.   Historically, ATX has generated substantial
       revenues. If those results were to continue, post-merger CoreComm could
       manifest better financial results, capital raising abilities and
       available cash than CoreComm alone.

     - The complementary nature of CoreComm's and ATX's businesses.   In
       addition to the synergies discussed above, the board of directors also
       focused on the complementary features of ATX's and CoreComm's businesses.
       For instance, ATX employs "Smart Build" network architecture similar to
       that utilized by CoreComm.

     - Opinion of CoreComm's financial advisor.   Goldman, Sachs & Co. has
       delivered its written opinion, dated March 9, 2000, to the board of
       directors of CoreComm that, as of that date, the stock consideration and
       the cash consideration, in the aggregate, to be paid by CoreComm under
       the ATX merger agreement, as in effect on that date, was fair from a
       financial point of view to CoreComm. The opinion of Goldman Sachs does
       not constitute a recommendation as to how any holder of CoreComm common
       shares should vote with respect to the transaction. The board of
       directors of CoreComm also reviewed the methodologies used by Goldman
       Sachs in rendering this opinion in valuing ATX. A copy of Goldman Sachs'
       written opinion dated August 10, 2000 is attached to this joint proxy
       statement and prospectus as Annex G, and the shareholders of CoreComm are

                                       125
<PAGE>   139

       encouraged to, and should read this opinion in its entirety. Please also
       see the section of this joint proxy statement and the prospectus
       entitled, "The Merger between CoreComm and ATX -- The Opinion of Goldman
       Sachs" for more detailed information regarding Goldman Sachs' opinion.

     The CoreComm board of directors also considered the following potentially
negative factors in its deliberations concerning the merger:

     - ATX is a private entity.   The fact that ATX is a newly-formed
       corporation derived from two limited partnerships meant that analyzing
       its financial information, especially in light of absence of historical
       financial information prepared in accordance with United States generally
       accepted accounting principles, was more difficult than if ATX had been a
       publicly-traded entity. In addition, ATX's management infrastructure is
       not as well-developed as that of a publicly-traded company.

     - Inherent challenges to effecting the transaction.   The inherent
       challenges to effecting the ATX merger and the attendant risk that
       management resources may be diverted from other strategic opportunities
       and from operational matters for an extended period of time.

     - The possibility that, despite the efforts of the combined company,
       technical and management personnel might not remain employees with
       post-merger CoreComm. There is a risk of management and employee
       disruption with the ATX merger, including the risk that despite the
       efforts of post-merger CoreComm following the ATX merger, key technical,
       sales and management personnel might not remain employed by post-merger
       CoreComm.

     The board of directors of CoreComm concluded that the potential negative
factors considered by it were not sufficient, either individually or
collectively, to outweigh the advantages of the ATX merger.

THE OPINION OF GOLDMAN SACHS

     Opinion of Goldman Sachs to CoreComm in the ATX Transaction. Goldman Sachs
has delivered its written opinions, dated March 9, 2000 and August 10, 2000 to
the board of directors of CoreComm that, as of these dates, the stock
consideration and the cash consideration in the aggregate, to be paid by
CoreComm under the March 9, 2000 ATX merger agreement and that agreement, as
amended through July 31, 2000, respectively, was fair from a financial point of
view to CoreComm.

     THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED AUGUST 10,
2000, WHICH IDENTIFIES ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON
THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX G AND
IS INCORPORATED HEREIN BY REFERENCE IN THIS JOINT PROXY STATEMENT AND
PROSPECTUS. SHAREHOLDERS OF CORECOMM ARE URGED TO, AND SHOULD, READ THIS OPINION
IN ITS ENTIRETY.

<PAGE>   140

     In connection with its August 10, 2000 opinion, Goldman Sachs reviewed,
among other things:

     - the ATX merger agreement, as amended through July 31, 2000,

     - the annual reports to shareholders and annual reports on Form 10-K of
       CoreComm for the year ended December 31, 1999,

     - audited cash basis financial statements of ATX for the two years ended
       December 31, 1997,

     - draft GAAP basis financial statements of ATX for the three years ended
       December 31, 1999,

     - interim reports to shareholders and Quarterly Reports on Form 10-Q of
       CoreComm,

     - other communications from CoreComm to their shareholders,

     - other information related to ATX,

     - internal financial analyses and forecasts for CoreComm and ATX prepared
       by their respective managements, and

     - internal financial analyses and forecasts for ATX prepared by the
       management of ATX and approved for use in its analyses by the management
       of CoreComm, which is referred to as the ATX forecasts.

     Goldman Sachs also held discussions with members of the senior managements
of CoreComm and ATX regarding the past and current business operations,
financial condition, and future prospects of their respective companies. In
addition, Goldman Sachs:

     - reviewed the reported price and trading activity for the CoreComm common
       stock and performed various valuation analyses of CoreComm based upon
       projections by the management of CoreComm and other financial and stock
       market information,

     - compared certain financial and stock market information for CoreComm and
       ATX with similar information for certain other companies the securities
       of which are publicly traded, and

     - reviewed the financial terms of certain recent business combinations and
       performed such other studies and analyses as it considered appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of rendering its opinion. Goldman Sachs assumed with
CoreComm's consent that the ATX forecasts had been reasonably prepared and
reflected the best currently available estimates and judgments of ATX. In
addition, Goldman Sachs did not make an independent evaluation or appraisal of
the assets and liabilities of CoreComm or ATX or any of their respective
subsidiaries and Goldman Sachs has not been furnished with any such evaluation
or appraisal. The opinion of Goldman Sachs was provided for the information and
assistance of the board of directors of CoreComm in connection with its
                                       127
<PAGE>   141

consideration of the transaction contemplated by the ATX merger agreement and
this opinion does not constitute a recommendation as to how any holder of
CoreComm shares should vote with respect to such transaction.

     CoreComm and ATX did not impose any material limitations on Goldman Sachs
in performing its financial analyses and investigations.

     The following is a summary of the material financial analyses used by
Goldman Sachs in connection with providing its opinion to CoreComm's board of
directors on March 9, 2000.

     In connection with its August 10, 2000 opinion, Goldman Sachs updated
certain of the analyses described below and the results of such updates did not
change Goldman Sachs' opinion as to the fairness, from a financial point of
view, of the stock consideration and the cash consideration, in the aggregate,
to be paid by CoreComm under the ATX merger agreement. The updated Goldman Sachs
discounted cash flow analysis of ATX on a standalone basis used the same
methodology described below under "Discounted Cash Flow Analysis" below but used
a range of discount rates of 15% to 35% and a range of EBITDA exit multiples of
9x to 12x yielded values as of June 30, 2000 ranging from $464,000,000 to
$1,161,000,000.

     THE FOLLOWING SUMMARIES OF FINANCIAL ANALYSES INCLUDE INFORMATION PRESENTED
IN TABULAR FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT OF EACH
SUMMARY.

     Historical Stock Trading Analysis.   Goldman Sachs reviewed the historical
trading performance of the CoreComm common stock and three composite indices
comprised of certain publicly traded competitive local exchange carriers for the
period from May 1, 1999 to March 1, 2000. The first composite index consisted of
Allegiance Telecom, Focal, Mpower Communications and US LEC, or "Smart Build
Competitive Local Exchange Carriers." The second composite index consisted of
CTC, e.spire and ITC DeltaCom, or "Other competitive local exchange carriers."
The third composite index was Network Plus, Inc. These companies were chosen
because they are publicly-traded companies with operations that for purposes of
analysis may be considered similar to ATX Telecommunications Services, Inc.

     Selected Companies Analysis.   Goldman Sachs reviewed and compared certain
financial information relating to CoreComm and ATX to corresponding financial
information, ratios and public market multiples for the following publicly
traded corporations in the competitive local exchange carrier industry:

                                       128
<PAGE>   142

     The selected companies were chosen because they are publicly traded
companies with operations that for purposes of analysis may be considered
similar to CoreComm and ATX.

     Goldman Sachs also calculated and compared various financial multiples and
ratios based on information it obtained from SEC filings, Goldman Sachs Equity
Research estimates, other equity research estimates and other publicly available
data. The multiples and ratios for CoreComm were calculated using the CoreComm
common stock closing price on March 7, 2000. The multiples and ratios for
CoreComm were based on information provided by its management. The multiples and
ratios for each of the selected comparable competitive local exchange carriers
were based on the most recent publicly available information. Goldman Sachs'
analyses of the selected companies compared the following to the results for
CoreComm:

     - levered market capitalization, which is the market value of fully diluted
       common equity plus the book value of debt and capital lease obligations
       less cash, as a multiple of gross plant, property and equipment (PPE),

     - levered market capitalization as a multiple of net PPE,

     - levered market capitalization as a multiple of estimated 2000 revenue,

     - levered market capitalization as a multiple of estimated 2001 revenue,
       and

     - levered market capitalization as a multiple of estimated 2002 earnings
       before interest, taxes, depreciation and amortization, or EBITDA.

     The results of these analyses are summarized as follows:

     Discounted Cash Flow Analysis.   Goldman Sachs performed a discounted cash
flow analysis of ATX Telecommunications Services, Inc. on a standalone basis
based upon forecasts provided by ATX management and approved for use in
connection with the

                                       129
<PAGE>   143

opinion by the management of CoreComm. Goldman Sachs calculated a range of
values for the common stock based on the sum of (i) the discounted present value
of the five-year (2000-2004) stream of projected after-tax cash flows of ATX,
using a range of weighted average cost of capital, or WACC, discount rates
between 14% and 17%; and (ii) the present value of ATX of the terminal value of
ATX Telecommunications Services, Inc. in 2004, assuming an EBITDA exit multiple
range between 9.0x and 12.0x. The above financial sensitivity analysis yielded
values as of January 1, 2000 ranging from $759,000,000 to $1,121,000,000.

     Goldman Sachs also examined the sensitivity of the discounted cash flow
value of ATX to changes in operating assumptions. Using for illustration
purposes a WACC discount rate of 15% and an EBITDA exit multiple of 11.0x,
Goldman Sachs calculated the value of ATX assuming the increase or decrease of
up to 20% in the variations of number of new consultants and their respective
productivities. Finally, using the same illustrative scenario, Goldman Sachs
analyzed the value of ATX assuming increases in capital expenditures and
attrition, which is the number of local lines and their associated revenues
terminated in a given year. The results of these analyses are as follows:

     Pro Forma Merger Analysis.   Goldman Sachs prepared pro forma analyses of
the financial impact of the ATX merger using discounted cash flows estimates for
the five year period of 2000 through 2004 for CoreComm and ATX prepared by their
respective managements. For each of the years 2000 through 2004, Goldman Sachs
assumed the consideration to be paid to ATX stockholders comprised of 56% stock,
28% convertible

                                       131
<PAGE>   145

stock and 17% cash and a ten day weighted average share price of $45.10 per
share of CoreComm common stock, a 10% premium to the closing price of CoreComm
common stock on March 7, 2000. Based on these analyses, the proposed transaction
would be slightly dilutive to CoreComm's stockholders on a 2004 discounted cash
flow basis.

     Pro Forma Contribution Analysis.   Goldman Sachs reviewed selected
estimated future operating and financial information for CoreComm, ATX and the
combined company resulting from the merger based on their respective
managements' financial forecasts. Goldman Sachs also analyzed the relative
income statement contribution of CoreComm and ATX to the combined company based
upon estimated results for the years 1999 through 2004.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinions. In arriving at its fairness determination,
Goldman Sachs considered the results of all of these analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
CoreComm or ATX or the contemplated transaction.

     The analyses were prepared solely for purposes of Goldman Sachs' providing
its opinions to the CoreComm board of directors as to the fairness from a
financial point of view to CoreComm of the stock consideration and the cash
consideration, in the aggregate, to be paid by CoreComm under the ATX merger
agreement. These analyses do not purport to be appraisals or necessarily reflect
the prices at which businesses or securities actually may be sold. Analyses
based upon forecasts of future results are not necessarily indicative of actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Because these analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of CoreComm, ATX, Goldman Sachs or any other
person assumes responsibility if future results are materially different from
those forecast.

     As described above, Goldman Sachs' March 9, 2000 opinion to the board of
directors of CoreComm was one of many factors taken into consideration by the
CoreComm board of directors in making its determination to approve the ATX
merger agreement. The foregoing is a summary of the material financial analyses
used by Goldman Sachs in connection with providing its opinions but it does not
purport to be a complete description of the analyses performed by Goldman Sachs.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. Goldman Sachs has acted
as CoreComm's financial advisor in connection with, and has participated in
negotiations leading to, the ATX merger agreement.

                                       132
<PAGE>   146

     Goldman Sachs may also provide investment banking services to CoreComm in
the future. CoreComm selected Goldman Sachs as its financial advisor because it
is a nationally recognized investment banking firm that has substantial
experience in transactions similar to the ATX merger.

     Goldman Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to
time effect transactions and hold positions in the securities or options on
securities of CoreComm for its own account and for the account of customers.

     Under a letter agreement dated December 28, 1999, CoreComm exclusively
engaged Goldman Sachs to act as its financial advisor and to undertake a study
to enable it to render an opinion in connection with the possible acquisition of
all or a portion of the equity interests or assets of ATX. Under the terms of
this engagement letter, CoreComm has agreed to pay Goldman Sachs a transaction
fee based on the outcome of the transaction as follows:

     - if at least 50% of the outstanding equity interests or assets (based on
       the book value thereof) of ATX is acquired in one or more transactions,
       Goldman Sachs will be paid a transaction fee of $7,000,000; and

     - if less than 50% of the outstanding equity interests or assets (based on
       the book value thereof) of ATX is acquired, Goldman Sachs will be paid a
       mutually acceptable transaction fee.

     CoreComm has agreed to pay the transaction fee to Goldman Sachs in cash
upon consummation of such acquisition.

     CoreComm also has agreed to reimburse Goldman Sachs for its reasonable
out-of-pocket expenses, including attorneys' fees, and to indemnify Goldman
Sachs against certain liabilities, including certain liabilities under the
federal securities laws.

     Accelerated Vesting of CoreComm Stock Options.   All outstanding options
under CoreComm's 1998 and 1999 stock option plans will vest and become
exercisable upon the completion of the ATX merger. CoreComm has obtained waivers
from its directors and officers and is seeking waivers from its other employees
to forego the accelerated vesting of these options.

APPRAISAL RIGHTS

     CoreComm shareholders have no appraisal rights with respect to the ATX
merger. CoreComm shareholders will have appraisal rights with respect to the
domestication merger. Please read the section of this discussion of the merger
transactions entitled "-- The Domestication Merger -- Appraisal Rights" for more
information regarding appraisal rights with respect to the domestication merger.

                            THE DOMESTICATION MERGER

PRINCIPAL REASONS FOR THE DOMESTICATION PROPOSAL

     The CoreComm board of directors has determined that the domestication
merger is fair and in the best interests of CoreComm and its shareholders and
has unanimously approved the domestication merger. The domestication merger will
not occur unless either the Voyager merger or the ATX merger or both mergers are
to be completed immediately after the completion of the domestication merger.
ACCORDINGLY, CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF
CORECOMM VOTE "FOR" AUTHORIZATION OF THE DOMESTICATION MERGER SO LONG AS EITHER
THE VOYAGER MERGER OR THE ATX MERGER OR BOTH MERGERS WILL BE COMPLETED
IMMEDIATELY AFTER THE COMPLETION OF THE DOMESTICATION MERGER.

     The domestication merger is motivated principally by the tax efficiencies
that the board of directors of CoreComm believes will be achieved if CoreComm
changes its domicile from Bermuda to the State of Delaware in the United States
immediately prior to completing either the ATX merger or the Voyager merger.

     If the Voyager merger occurs but the ATX merger does not occur, and if
CoreComm does not change its domicile immediately prior to the Voyager merger,
the Voyager merger would not be able to be structured as a tax-free transaction.
This would effectively have prevented Voyager from entering into the
transaction.

     If only the ATX merger occurs or if both the ATX merger and the Voyager
merger occur, the board of directors of CoreComm believes it is also in the best
interests of

                                       134
<PAGE>   148

CoreComm and its shareholders to change CoreComm's domicile to the United States
in order to avoid the tax inefficiencies that would result if CoreComm were to
remain a Bermuda corporation in which case it would become a subsidiary of a
Delaware parent (post-merger CoreComm). Specifically, as a Bermuda company, it
would not be able to consolidate for United States federal income tax purposes
with post-merger CoreComm. Moreover, if CoreComm remained a Bermuda corporation
after it became a wholly-owned subsidiary of post-merger CoreComm, CoreComm
would become subject to the "deemed dividend" and other provisions applicable to
"controlled foreign corporations" under the "subpart F" rules of the United
States federal income tax code of 1986, as amended, which were enacted in order
to discourage U.S. companies from conducting certain operations through foreign
subsidiaries.

APPRAISAL RIGHTS

     If you are a shareholder of CoreComm who does not vote in favor of the
domestication merger and are not satisfied that you have been offered the fair
value of your common shares, you may (within one month after the date notice of
the CoreComm Special General Meeting was given) apply to the Bermuda courts to
appraise the fair value of your common shares.

     Within one month after the Bermuda court's appraisal, CoreComm will be
entitled to pay you an amount equal to the value of your common shares as
appraised by the court. However, where the court has appraised any shares under
this procedure and the amalgamation has been completed prior to the appraisal
then, within one month after the court's appraisal, if the amount paid to you
for your shares is less than the appraisal by the court, CoreComm will pay to
you the difference between the amount paid to you and the value appraised by the
court. There is no appeal from an appraisal by the court under this procedure.

                         THE INCREASE IN SHARE CAPITAL

     CoreComm's board of directors has determined that the increase in share
capital of CoreComm to 200 million common shares and 5 million preferred shares
is in the best interests of CoreComm and its shareholders and has unanimously
approved the increase in share capital. ACCORDINGLY, CORECOMM'S BOARD OF
DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" THE PROPOSAL
TO INCREASE CORECOMM'S SHARE CAPITAL.

     The board of directors of CoreComm recommends that shareholders vote for
the increase in share capital in order to facilitate future acquisitions by
CoreComm in the event the ATX merger and the Voyager merger do not occur. The
increase in share capital will not be needed if either the ATX merger or the
Voyager merger occurs, because post-merger CoreComm will have authorized share
capital of 200 million common shares and 5 million preferred shares.

               THE MERGER AGREEMENT BETWEEN CORECOMM AND VOYAGER

     The following is a brief summary of the significant provisions of the
merger agreement between CoreComm and Voyager. A copy of the Voyager merger
agreement is attached as Annex A and incorporated into this joint proxy
statement and prospectus. YOU SHOULD READ THE VOYAGER MERGER AGREEMENT CAREFULLY
AND IN ITS ENTIRETY.

GENERAL

     The Voyager merger agreement provides for the merger of a newly-formed
wholly-owned subsidiary of CoreComm with and into Voyager. Voyager will survive
and become a wholly-owned subsidiary of post-merger CoreComm.

MERGER CONSIDERATION

     In the Voyager merger, each outstanding share of common stock, par value
$0.0001 per share, of Voyager will be converted into the right to receive $3.00
in cash and 0.292 of a share of common stock of post-merger CoreComm based on an
exchange ratio calculated as follows:

     If the average trading price prior to closing per common share of CoreComm
is:

     - equal to or greater than $41.17 and equal to or less than $56.97 (subject
       to adjustment as described below), the exchange ratio will be fixed at
       0.292;

     - greater than $56.97, the exchange ratio will be calculated by dividing
       $16.64 by the average trading price per CoreComm common share; or

     - less than $41.17 and equal to or greater than $33.03, the exchange ratio
       will be calculated by dividing $12.02 by the average trading price per
       CoreComm common share; or

     - less than $33.03, then Voyager has the right to notify CoreComm it wishes
       to terminate the Voyager merger agreement:

         - if Voyager gives that notification, CoreComm can prevent the
           termination by adjusting the exchange ratio so that the Voyager
           stockholders receive $12.02 worth of post-merger CoreComm common
           stock per share of Voyager common stock; and

                                       136
<PAGE>   150

         - if Voyager does not give that notification, the exchange ratio will
           be 0.3639 shares of post-merger CoreComm common stock for each share
           of Voyager common stock, subject to adjustments described below to
           preserve the tax-free treatment of the Voyager merger.

     The average trading price per CoreComm common share will be computed by
taking the volume weighted average trading price of CoreComm common shares for
ten randomly selected trading days out of the 20 consecutive trading days ending
with the last day prior to the closing of the Voyager merger.

ADJUSTMENTS TO STOCK CONSIDERATION

     If the average trading price of CoreComm common shares is below $33.03,
Voyager has the right to notify CoreComm that it wishes to terminate the Voyager
merger agreement. The average trading price will be calculated as of the end of
the trading day prior to the scheduled closing date of the Voyager merger, so it
will only be possible to determine whether Voyager has the right to give the
termination notification on that date.

 --  Voyager elects not to give the termination notice:

     Voyager stockholders will be entitled to receive merger consideration with
     a total value equal to 0.3639 of a share of common stock of post-merger
     CoreComm, plus $3.00 for each share of Voyager common stock.

     In order to ensure that the Voyager merger will be treated as a tax-free
     reorganization under the federal tax laws, the composition of the
     consideration will be adjusted to 80% post-merger CoreComm common stock and
     20% cash. The value of the post-merger CoreComm common stock for purposes
     of the adjustment will be based on the trading price of the CoreComm common
     shares on the date the Voyager merger closes.

     The following table shows, for various assumed trading prices of CoreComm
     common stock on the closing date:

   - the total value of the consideration to be received;

   - the composition, cash versus stock, of the consideration after the
     adjustment; and

   - the fraction of a share of post-merger CoreComm common stock to be issued
     for each share of Voyager common stock, after adjustment.

</TABLE>

 --  Voyager elects to give the termination notice:

   - CoreComm may elect to adjust the fraction of a share of post-merger
     CoreComm common stock to be issued in respect of each share of Voyager
     common stock so that the value of that fraction of a share will be $12.02.
     In that case, Voyager may not terminate the Voyager merger agreement.

     For example, if the average trading price of CoreComm common shares were
     $20.00, then Voyager could give CoreComm notice of its intention to
     terminate the Voyager merger agreement. If CoreComm elects not to accept
     the termination, it would be required to increase the fraction of a share
     of post-merger CoreComm common stock to be issued in respect of each share
     of Voyager common stock to 0.601 of a share. In this example, Voyager
     stockholders would receive 0.601 of a share of post-merger CoreComm common
     stock plus $3.00 in cash for each share of Voyager common stock, totaling
     $15.02 worth of consideration per share.

     The following table sets forth the exchange ratios between post-merger
     CoreComm common stock and Voyager common stock for some average trading
     prices of CoreComm common shares, assuming that Voyager notifies CoreComm
     of its intention to terminate the Voyager merger agreement and CoreComm
     elects to adjust the exchange ratio:

</TABLE>

   - CoreComm may also elect not to adjust the exchange ratio, in which case the
     Voyager merger agreement will terminate and the Voyager merger will not
     occur.

     To date, the Voyager board of directors has not made any decision as to
whether Voyager will notify CoreComm that it wishes to terminate the Voyager
merger agreement if the average trading price is less than $33.03. To date, the
CoreComm board of directors has not made any decision as to whether it would
elect to adjust the

                                       138
<PAGE>   152

exchange ratio between Voyager common stock and post-merger CoreComm common
stock.

     Adjustments will also be required to be made to the exchange ratio if (1)
the closing of the Voyager merger has not occurred on or prior to July 15, 2000,
(2) CoreComm has engaged in a transaction that would (x) require the approval of
the shareholders of CoreComm, (y) require CoreComm to include information
relating to the transaction in the pro forma financial statements that are
required to be contained in this joint proxy statement and prospectus or (z)
require CoreComm to amend or restate its pro forma financial statements in any
material manner, and (3) all other conditions to closing have been satisfied (or
waived by the party entitled to waive the condition) or are capable of being
satisfied on that date with reasonable best efforts.

     In these circumstances, commencing on the later to occur of July 16, 2000
and the first business day after which the circumstances described above are
present, which is referred to as the trigger date, the fraction of a share of
post-merger CoreComm common stock that a Voyager stockholder will be entitled to
receive will be fixed at 0.292 so long as the average trading price per CoreComm
common share does not exceed $47.875 multiplied by the applicable collar
percentage, which will be increased by an additional five percentage points per
each 31 day period beginning on the sixteenth calendar day following the trigger
date.

     The following chart presents some examples of how the exchange ratio and
maximum value of the merger consideration would be adjusted assuming a base
stock price of $47.875 and a trigger date of July 16, 2000:

     In addition, the base amount of $47.875 is to be adjusted:

     - upon any reclassification, recapitalization, stock split, reverse stock
       split, combination or exchange of shares or any dividend payable in
       CoreComm common shares so that the existing Voyager stockholders achieve
       the same economic effect originally contemplated; and

     - upon any distribution to CoreComm shareholders of, or rights or warrants
       for, capital stock, other than common stock debt, other assets, other
       than cash dividends or by reducing the base amount in a manner designed
       to reflect the decrease in value achieved by the distribution.

                                       139
<PAGE>   153

     CoreComm may only effect a distribution described in this paragraph, if the
distribution does not include operating assets that are required to maintain the
current operating businesses of CoreComm, Inc. (a subsidiary of CoreComm) and
the distribution of such operating assets would not have a material adverse
effect on the current operating businesses of CoreComm, Inc., provided that this
paragraph shall not prohibit a distribution of the local multipoint distribution
service licenses and related assets.

     If the average trading price of CoreComm common shares is above $33.03, the
fraction of a share of post-merger CoreComm common stock to be received by
Voyager stockholders for each share of Voyager common stock will be adjusted,
based on the average trading price. Under that adjustment formula, Voyager
stockholders will receive up to a maximum of $16.64 worth of post-merger
CoreComm common stock for each share of Voyager common stock plus the $3.00 in
cash.

     All per-share consideration may be adjusted if CoreComm engages in any
transaction that has the mathematical effect of reducing the value of each share
of CoreComm common stock while preserving CoreComm's existing shareholder's
total value, such as a stock split or spin-off. In that case, the shares of
post-merger CoreComm common stock to be received by Voyager's stockholders will
be increased to preserve the value to be received.

     Post-merger CoreComm will not issue fractional shares in the Voyager
merger. As a result, the total number of shares of post-merger CoreComm common
stock that each Voyager stockholder receives in the Voyager merger will be
rounded down to the nearest whole number. Each of these stockholders will also
receive a cash payment for the remaining fractional share.


POST CLOSING CAPITALIZATION



     Assuming that the average trading price of CoreComm common shares is $12.00
and the closing trading price of CoreComm common shares is $12.00 on the trading
day prior to completing the Voyager merger, following the Voyager merger and
without taking into account the ATX merger, post-merger CoreComm will have
approximately 55.7 million shares of its common stock outstanding. Voyager
stockholders will own approximately 27.9% of that total, and the remaining 72.1%
will be owned by CoreComm shareholders as of immediately prior to the Voyager
merger.



     Assuming that the average trading price of CoreComm common shares is $12.00
and the closing trading price of CoreComm common shares is $12.00 on the trading
day prior to completing the Voyager merger, following the ATX merger and the
Voyager merger, post-merger CoreComm will have approximately 68.1 million shares
of its common stock outstanding. Voyager stockholders will own approximately
22.8% of that total. Current ATX stockholders will own approximately 18.2% of
that total, and the remaining 59.0% will be owned by CoreComm shareholders as of
immediately prior to the Voyager merger.


                                       140
<PAGE>   154


     The calculations contained in the preceding two paragraphs assume that
Voyager does not notify CoreComm that it wishes to terminate the Voyager merger
agreement, assume that the Voyager merger agreement is not terminated, assume
that the stock to be received by Voyager stockholders will represent 80% of the
total value of the Voyager stockholders' merger consideration and do not take
into account the exercise of any outstanding stock options or warrants or the
conversion of any convertible securities that would result in the issuance of
the common equity of any of the companies involved.


ADJUSTMENTS TO STOCK AND CASH CONSIDERATION

     The amount of cash consideration, which is $3.00 for each share of Voyager
common stock, that Voyager stockholders are entitled to receive could be
adjusted if either of the tax opinions to be delivered by counsel to CoreComm or
Voyager is not reasonably expected to be delivered because less than 80% of the
value of the merger consideration would be in the form of post-merger CoreComm
common stock. In this case, the number of common shares of post-merger CoreComm
to be received will be increased, and accordingly the amount of cash to be
received will be reduced, so that the value of the shares of common stock of
post-merger CoreComm to be received in the Voyager merger will constitute 80% of
the total merger consideration. The purpose of this adjustment is to ensure that
the transaction will be treated as a tax-free reorganization under federal tax
laws.

EFFECTIVE TIME OF THE VOYAGER MERGER

     Promptly after the satisfaction or waiver of the conditions of the Voyager
merger set forth in the Voyager merger agreement, CoreComm will file a
certificate of merger with the Secretary of State of the State of Delaware. When
this filing has been made, a newly-formed subsidiary of CoreComm will be merged
with and into Voyager, and the separate corporate existence of this merger
subsidiary will cease. Voyager will survive the Voyager merger and exist as a
wholly-owned subsidiary of post-merger CoreComm. The directors of Voyager
immediately following the Voyager merger will be those of CoreComm's merger
subsidiary. Immediately following the Voyager merger, the officers of Voyager
immediately prior to the Voyager merger will continue as the officers of
Voyager.

VOYAGER STOCK OPTIONS

     Each outstanding Voyager stock option will become an option to acquire a
number of shares of post-merger CoreComm common stock equal to the number of
shares of Voyager common stock subject to the option immediately prior to the
effective time using a formula based on the exchange ratio used to determine the
fraction of a share of post-merger CoreComm common stock to be received by
Voyager stockholders in connection with the Voyager merger plus the quotient
obtained by dividing the cash consideration received by Voyager stockholders in
connection with the merger by the average trading price of CoreComm common
shares. Under the Voyager stock option plan, all outstanding options will vest
and become exercisable upon completion of the Voyager merger. The issuance of
the shares of post-merger CoreComm common stock to

                                       141
<PAGE>   155

be received upon exercise of the options issued by post-merger CoreComm will be
registered by post-merger CoreComm.

EXCHANGE OF CERTIFICATES

     Post-merger CoreComm will appoint an exchange agent to handle the exchange
of the Voyager common stock certificates in the Voyager merger. Once the Voyager
merger is complete, post-merger CoreComm will deposit with the exchange agent
the certificates representing post-merger CoreComm common stock, the aggregate
cash consideration, including the cash to be provided instead of fractional
shares, and any related dividends or distributions, issuable in the merger in
exchange for outstanding shares of Voyager common stock.

     Soon after the closing of the Voyager merger, the exchange agent will send
to each holder of Voyager common stock a letter of transmittal for use in the
exchange and instructions explaining how to surrender certificates to the
exchange agent. Holders who surrender their certificates to the exchange agent,
together with a properly completed letter of transmittal, will receive the
appropriate merger consideration. Holders of unexchanged stock certificates will
receive any dividends or other distributions payable by post-merger CoreComm
after the Voyager merger only after their certificates are surrendered. VOYAGER
STOCKHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD.

     No certificates or scrip representing CoreComm common stock will be issued
upon surrender for exchange of Voyager certificates. Cash will be issued instead
of fractional shares of post-merger CoreComm common stock otherwise issuable
upon surrender of those certificates, based on the closing price for CoreComm
common shares on Nasdaq on the first business day immediately following the
closing of the Voyager merger.

     If Voyager stock certificates have been lost, stolen or destroyed, Voyager
stockholders will only be entitled to obtain post-merger CoreComm common stock
and the cash consideration by providing an affidavit of loss and, if required by
post-merger CoreComm, posting a bond in an amount sufficient to protect
post-merger CoreComm against claims related to the Voyager certificates.

advisors or representatives not to, solicit, initiate, or encourage (including
by way of furnishing non-public information), or take any action to facilitate,
any inquiries or the making of any proposal that constitutes an acquisition
proposal or any inquiries or making of any proposal that constitutes, or is

negotiations with, any person that makes an unsolicited written acquisition
proposal if:

     - after consultation with its outside legal counsel, the Voyager board
       determines in good faith that these actions are necessary for the Voyager
       board to comply with its fiduciary duties to the Voyager stockholders
       under applicable law;

     - the proposal is not subject to financing contingencies or is, in the good

       would result in a more favorable transaction to Voyager's stockholders
       from a financial point of view; and

     - Voyager enters into a confidentiality agreement with the person making
       the proposal.

     For any acquisition proposal that it receives, Voyager agreed to notify
CoreComm of the identity of the company making the proposal and the material

proposal. Additionally, Voyager agreed to inform CoreComm of, and provide
CoreComm with copies of, any material changes to the proposal. Voyager also

     Voyager has agreed to carry on its business, and cause its subsidiaries to
carry on their businesses, in the usual, regular and ordinary course of
business, consistent with past practice and in accordance with and to the extent

than would be applied in the absence of the

       complete the transactions contemplated by the Voyager merger agreement.

CONDUCT OF BUSINESS BY CORECOMM

     Without the prior written consent of Voyager, CoreComm will not declare,
set aside or pay any dividends or make any other distributions, except for
dividends paid by a subsidiary of CoreComm to CoreComm or any subsidiary of
CoreComm that is, directly or indirectly, wholly-owned by CoreComm and except as
permitted by the Voyager merger agreement.

MEETINGS OF STOCKHOLDERS; OBLIGATIONS TO RECOMMEND

     Voyager has agreed to take all actions necessary to convene a meeting of
its stockholders and to consider and vote upon the approval of the Voyager
merger agreement and the Voyager merger and CoreComm has agreed to take all
actions necessary to convene a meeting of its shareholders to consider and vote
upon the Voyager merger agreement and the issuance of common stock of CoreComm
in connection with the Voyager merger.

                                       147
<PAGE>   161

     The Voyager board has agreed to recommend to its stockholders the adoption
of the Voyager merger agreement. The Voyager board is not permitted to withdraw
or modify its recommendation unless:

     - Voyager has complied with the restrictions of solicitation described
       above;

     - there is a pending superior proposal;

     - the Voyager board determines in good faith that this action is necessary
       to comply with its fiduciary duty; and

     - Voyager delivers prior notice to CoreComm that it intends to take this
       action.

     The CoreComm board has agreed to recommend to its shareholders that they
approve and adopt the Voyager merger agreement.

TAX-FREE TREATMENT

     Neither of CoreComm nor Voyager will take, or fail to take, or cause to be
taken or fail to cause to be taken, any action, whether before or after the
closing of the Voyager merger, which action or failure to take any action would
cause the merger to fail to constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code or a transaction that, together with
the reincorporation of CoreComm from a Bermuda corporation to a Delaware
corporation, qualifies as an exchange under the provisions of Section 351 of the
Internal Revenue Code and which is treated for U.S. federal income tax purposes
as a transfer of Voyager common stock by the stockholders of Voyager to CoreComm
in exchange for the merger consideration. However, it is further intended by
CoreComm and Voyager that if the ATX merger occurs prior to the Voyager merger,
and the Voyager merger agreement is assigned to post-merger CoreComm, then the
ATX merger, the ATX recapitalization and the transactions described in the
Voyager merger agreement will be treated for U.S. federal income tax purposes as
one integrated transaction qualifying as an exchange under the provisions of
Section 351 of the Internal Revenue Code in which the stockholders of Voyager
transfer Voyager common stock in exchange for post-merger CoreComm common stock.

CONSENTS AND APPROVALS

     CoreComm and Voyager have agreed to make all necessary filings, including
those under U.S. antitrust laws and under the Telecommunications Act, and to use
all reasonable efforts to obtain all consents and approvals required in
connection with the closing of the transactions contemplated by the Voyager
merger agreement.

LISTING APPLICATION

     CoreComm and Voyager have agreed to cooperate in the preparation and
submission to Nasdaq of all reports, applications and other documents that may
be necessary to enable all of the CoreComm common stock that will be outstanding
or reserved for issuance at the effective time of the Voyager merger to be
listed for trading on Nasdaq. CoreComm and Voyager will also use reasonable best
efforts to cause the

                                       148
<PAGE>   162

Voyager common stock to be de-listed from Nasdaq as soon as practicable
following the effective time of the Voyager merger.

PROXY STATEMENT; REGISTRATION STATEMENT

     CoreComm and Voyager will cooperate in the preparation and filing of the
joint proxy statement and prospectus.

EXPENSES

     Whether or not the Voyager merger is consummated, all expenses incurred in
connection with the Voyager merger agreement and the transactions contemplated
by the Voyager merger agreement will be paid by the party incurring the
expenses, except as described under the section of this joint proxy statement
and prospectus entitled "The Merger Agreement Between CoreComm and
Voyager -- Termination Fee."

OFFICERS' AND DIRECTORS' INDEMNIFICATION

     After the Voyager merger is completed, post-merger CoreComm will preserve
all rights to indemnification existing as of March 12, 2000, the date of the
Voyager merger agreement, in favor of any current or former director, officer or
employee of Voyager for a period of at least six years following the Voyager
merger. Post-merger CoreComm will also indemnify directors, officers, agents and
employees of Voyager against liabilities or claims arising before the Voyager
merger is completed and as a result of their positions at Voyager. Finally,
post-merger CoreComm will pay the applicable persons' legal and other expenses
incurred in connection with any proceeding arising out of any matter occurring
until the Voyager merger is completed, and, with limitations as to cost,
maintain Voyager's current directors' and officers' liability insurance in place
for at least six years following the Voyager merger.

EMPLOYEE BENEFITS

     Post-merger CoreComm has agreed that it will honor all obligations under
the existing terms of the employment and severance agreements to which Voyager
or any of its subsidiaries is presently a party, except as may otherwise be
agreed to by the parties to these agreements.

     CoreComm has agreed that individuals who are employed by Voyager or any of
its subsidiaries immediately prior to the closing of the Voyager merger will
remain employees of Voyager or any of its subsidiaries, provided, that no
employee will have the right to continued employment by post-merger CoreComm,
Voyager or any of their respective subsidiaries for any period of time after the
closing of the Voyager merger that is not otherwise required by law or contract.

     To the extent that any employee of Voyager or any of its subsidiaries
becomes a participant in any employee benefit plan maintained by post-merger
CoreComm or any of its subsidiaries, post-merger CoreComm will, or will cause
its subsidiaries to, give the affected employees full credit solely for the
purposes of eligibility and vesting under its employee benefits plans for the
affected employee's service with post-merger CoreComm,

                                       149
<PAGE>   163

Voyager or any affiliate of either one to the same extent recognized immediately
prior to the closing of the Voyager merger, provided, that the entry dates into
the employee benefit plans for the affected employees will be in the normal
course of the plan's administration, which may be the beginning of the plan
year.

     After the effective time of the Voyager merger, until the date post-merger
CoreComm determines in its sole discretion to modify, amend, terminate or
replace the benefit plans of Voyager, post-merger CoreComm will cause Voyager to
maintain its benefit plans (but not bonus or equity-based plans) on
substantially similar terms to those currently in effect. After the effective
time of the Voyager merger, if post-merger CoreComm decides to move any
employees of Voyager or its subsidiaries to a post-merger CoreComm employee
benefit plan, the affected employees will be permitted to participate in the
post-merger CoreComm employee benefit plan on terms substantially similar to
those provided to employees of post-merger CoreComm.

REINCORPORATION

     CoreComm has agreed to take any and all action that may be considered
advisable or necessary to reincorporate by merger from a Bermuda corporation to
a Delaware corporation so that at the time of the completion of the transactions
contemplated by the Voyager merger agreement, CoreComm is a Delaware
corporation.

THE ATX MERGER

     CoreComm will be permitted to take any and all action that may be
considered advisable or necessary to complete the ATX merger and none of the
actions taken in accordance with the ATX merger or consequences of these actions
will be considered a breach of a representation or warranty or be considered to
cause a failure of a condition to closing to be satisfied if, but for action or
consequence of the ATX merger, the condition would otherwise be satisfied.

OTHER ACTIONS

     Prior to the effective time of the Voyager merger, Voyager and CoreComm
will not, and will not permit any of their respective subsidiaries to, take any
action that would, or that could reasonably be expected to, result in any of the
conditions to the Voyager merger not being satisfied other than as provided in
the Voyager merger agreement.

     CoreComm will have the right to have its designated representatives, as
provided to Voyager from time to time, upon reasonable notice, present within
normal business hours and without material disruption to the business of Voyager
for consultation at Voyager's principal offices until the closing of the merger.
These designated representatives will have the right to review and become
familiar with the conduct of the business of Voyager and will be available to be
consulted and will have authority on behalf of CoreComm in regard to
consultation regarding Voyager's material decisions. CoreComm will take all
reasonable actions necessary to ensure that its designated representatives will
be readily available during normal business hours. Voyager will not take any
action involving any material decision without written notice to and favorable
consultation with

                                       150
<PAGE>   164

the designated representatives of CoreComm (which shall not be unreasonably
withheld, delayed or conditioned with respect to time or content), unless
CoreComm or its designated representatives have failed to respond within five
business days to the written notice.

     A material decision means, for purposes of the Voyager merger agreement,
any of the following to the extent the decision may affect the assets, the
obligations or the business of Voyager:

     - any purchase order, capital expenditure or other purchase of assets in
       excess of $100,000 in any instance to be delivered, or the payment for
       which will become due, after the closing of the Voyager merger;

     - the acceptance of any material customer contract or the establishment of
       any pricing policy that deviates in any material respect from the terms
       and conditions of current pricing policies as previously provided to
       CoreComm;

     - any general communication with customers related to the business or to
       the Voyager merger; or

     - a material change in material promotional or marketing decisions or
       policies.

NOTIFICATION OF SPECIFIED EVENTS

     CoreComm and Voyager have agreed to promptly notify each other of the
occurrence or non-occurrence of specified events, including if, prior to the
closing of the merger, CoreComm will enter into a definitive agreement for a
transaction that would affect timing of the transactions.

ADDITIONAL CONDITIONS TO OBLIGATIONS OF CORECOMM TO COMPLETE THE VOYAGER MERGER

     The obligation of CoreComm to complete the Voyager merger is also subject
to the following conditions:

       connection with the Voyager merger agreement will have been performed at
       or prior to the closing of the Voyager merger.

TERMINATION

     The Voyager merger agreement may be terminated at any time prior to the
closing of the Voyager merger by mutual written consent. Either CoreComm or
Voyager may terminate the Voyager merger agreement if:

     - any required approval of the CoreComm shareholders or Voyager
       stockholders has not been obtained at the applicable stockholder meeting;

     - any governmental entity has issued a final and non-appealable injunction
       that permanently enjoins the Voyager merger; or

     - the other party breaches any material representation, warranty, covenant
       or agreement contained in the Voyager merger agreement or if any
       representation or warranty shall have become untrue, and, in each case,
       as a result there would be a failure to satisfy a condition to the
       Voyager merger.

     The Voyager merger agreement may be terminated by Voyager if:

     - the Voyager board elects to terminate the Voyager merger agreement in
       order to recommend or approve a superior proposal, provided that Voyager:

         - has complied with all the terms of non-solicitation in accordance
           with the Voyager merger agreement;

         - has notified CoreComm in writing that it intends to terminate the
           Voyager merger agreement in order to recommend or approve a superior
           proposal;

         - has notified CoreComm of its intention to enter into a binding
           agreement with respect to a superior proposal and, after taking into
           account any modifications to the transactions contemplated by the
           Voyager merger agreement that CoreComm has then proposed in writing
           and not withdrawn, the Voyager board has determined that the other
           proposal is and continues to be a superior proposal; and

                                       153
<PAGE>   167

         - concurrently with the effectiveness of the termination, has paid to
           CoreComm the termination fee described under the section of this
           joint proxy statement and prospectus entitled "The Merger Agreement
           Between CoreComm and Voyager -- Termination Fees."

     - the Voyager merger is not consummated by October 31, 2000 and Voyager is
       not in material breach of its obligations, or

     - as of a date not more than three business days before the expected
       closing date of the merger, the average trading price of CoreComm common
       shares would be less than $33.03 and, following notification, CoreComm
       has not agreed to increase the exchange ratio so that each share of
       Voyager common stock will be exchanged for a fraction of a share of
       post-merger CoreComm common stock with a value equal to $12.02.

     The Voyager merger agreement may be terminated by CoreComm if:

     - the Voyager board shall have resolved to or has withdrawn, modified or
       changed in a manner adverse to CoreComm its approval or recommendation of
       the Voyager merger agreement; failed to include its recommendation
       regarding the Voyager merger in this joint proxy statement and
       prospectus; approved or recommended any acquisition proposal; entered
       into a definitive agreement with respect to a superior proposal; or made
       a public announcement of its intention to take any of the foregoing
       actions;

     - a tender offer or exchange offer for more than 15% of the outstanding
       shares of the Voyager common stock is commenced and the Voyager board
       fails to recommend against acceptance of this tender offer or exchange
       offer by its stockholders, including by taking no position with respect
       to the acceptance of the tender offer or exchange offer by its
       stockholders; and

     - it is not in material breach of its obligations under the Voyager merger
       agreement, on or after the later of October 31, 2000, and 120 days
       following the date on which CoreComm last made an initial announcement
       that it had entered into a definitive agreement for a transaction that
       would result in adjustments being made to the exchange ratio, if any
       specified conditions of the Voyager merger agreement have not been
       satisfied and have not been waived in writing by CoreComm prior to that
       date.

TERMINATION FEE

     The Voyager merger agreement requires Voyager to pay CoreComm a termination
fee of $19.0 million in cash if:

     - the Voyager merger agreement is terminated by the Voyager board in order
       to recommend or approve a superior proposal;

     - the Voyager merger agreement is terminated by CoreComm as a result of the
       Voyager board resolving to or having withdrawn, modified or changed in a
       manner adverse to CoreComm its approval or recommendation of the Voyager
       merger

                                       154
<PAGE>   168

       agreement; failing to include its recommendation regarding the Voyager
       merger in this joint proxy statement and prospectus; approving or
       recommending any acquisition proposal; entering into a definitive
       agreement with respect to a superior proposal; or making a public
       announcement of its intention to take any of the foregoing actions; or

     - the Voyager merger agreement is terminated by CoreComm due to the
       initiation of a tender offer or exchange offer for more than 15% of the
       outstanding shares of the Voyager common stock and the Voyager board's
       failure to recommend against acceptance of this tender offer or exchange
       offer by its stockholders, including by taking no position with respect
       to the acceptance of the tender offer or exchange offer by its
       stockholders.

AMENDMENTS

     CoreComm and Voyager may amend the Voyager merger agreement at any time
before or after the necessary approval by the stockholders of CoreComm and
Voyager, but in any event following authorization by the CoreComm board and the
Voyager board; provided, however, that after any required stockholder approval,
no amendment will be made that by law requires further approval by the
stockholders without obtaining their approval. The Voyager merger agreement was
amended for technical reasons by the parties to the agreement on August 10,
2000.

ASSIGNMENT TO POST-MERGER CORECOMM

     CoreComm shall assign all of its rights, interests and obligations under
the Voyager merger agreement to post-merger CoreComm (formerly ATX) upon
completion of the ATX merger if the completion occurs prior to the closing of
the Voyager merger, provided that, CoreComm will remain liable under the Voyager
merger agreement. If this assignment occurs, then post-merger CoreComm will
acquire Voyager by merging a wholly-owned domestic subsidiary of post-merger
CoreComm into Voyager.

RELATED AGREEMENTS

THE VOTING AGREEMENT

     In connection with the execution of the Voyager merger agreement, the
principal stockholders of Voyager (Media/Communications Partners II Limited
Partnership, Media/Communication Investors Limited Partnership, Christopher P.
Torto, Glenn R. Friedly, Apache Holdings II Limited Partnership and Apache
Holdings Limited Partnership), who together hold approximately 63.9% of the
voting power of Voyager's outstanding common stock, executed a voting agreement
with CoreComm, dated as of March 12, 2000.

     In the voting agreement, the principal stockholders of Voyager agreed:

     - to vote their shares in favor of the Voyager merger, the Voyager merger
       agreement and the transactions contemplated by the Voyager merger
       agreement;

                                       155
<PAGE>   169

     - to vote against any business combination other than the Voyager merger;

     - to grant, and did grant, CoreComm and its designees irrevocable proxies
       to vote their shares as required by the voting agreement; and

     - not to, nor permit any person under their control to, enter into any
       voting agreement or grant a proxy or power of attorney with respect to
       their shares held of record or beneficially owned by any of them or form
       a group under the securities law.

     In addition, the principal stockholders further agreed not to:

     - solicit, initiate, encourage (including by way of furnishing information
       or assistance) or take any other action to facilitate, any inquiry or the
       making of any proposal which constitutes, or may reasonably be expected
       to lead to, any acquisition proposal or agree to or endorse any
       acquisition proposal;

     - propose, enter into or participate in any discussions or negotiations
       regarding any of the foregoing;

     - furnish to any other person any information with respect to Voyager's
       business, properties or assets;

     - otherwise cooperate in any way with, or assist or participate in,
       facilitate or encourage, any effort or attempt by any other person to do
       or seek any of the foregoing.

     Furthermore, each principal stockholder agreed not to tender, sell, assign,
pledge or otherwise transfer its shares of Voyager common stock and to enter
into a stockholder agreement upon completion of the Voyager merger, which is
described below, in the event that the principal stockholder holds 7.5% or more
of post-merger CoreComm common stock.

     The voting agreement terminates upon the earliest to occur of:

     - the closing of the transactions contemplated by the Voyager merger
       agreement;

     - the date the Voyager merger agreement is terminated if terminated by
       Voyager because of a breach of any material representation, warranty or
       agreement on the part of CoreComm or if any representation or warranty of
       CoreComm in the Voyager merger agreement becomes untrue, which in each
       case results in a failure to satisfy a condition to closing;

     - the date the Voyager merger agreement is terminated if terminated by
       mutual consent of Voyager and CoreComm;

     - the date the Voyager merger agreement is terminated if terminated by
       either Voyager or CoreComm because a governmental entity has issued a
       final and nonappealable injunction that permanently enjoins the Voyager
       merger;

     - the date the Voyager merger agreement is terminated if terminated by
       Voyager if it is not in material breach of its obligations under the
       Voyager merger agreement and the Voyager merger has not occurred by
       October 31, 2000;

                                       156
<PAGE>   170

     - the date the Voyager merger agreement is terminated if terminated by
       Voyager because as of a date no more than three business days before the
       closing of the Voyager merger the average trading stock price of a
       CoreComm common share is less than $33.03 and CoreComm elected not to
       exercise its right to prevent Voyager from terminating the merger
       agreement by increasing the number of shares to be delivered to Voyager
       stockholders;

     - the date the Voyager merger agreement is terminated if terminated by
       Voyager because the shareholders of CoreComm have failed to approve the
       issuance of common shares of CoreComm in connection with the Voyager
       merger; or

     - 180 days after the date the Voyager merger agreement is terminated in
       accordance with its terms, other than as set forth above.

THE STOCKHOLDERS AGREEMENT

     In connection with the Voyager merger, each principal stockholder of
Voyager will execute a stockholders agreement, the terms of which provide that,
in the event that the principal stockholder holds 7.5% or more of post-merger
CoreComm common stock, that principal stockholder will:

     - Not acquire or agree to acquire ownership of any post-merger CoreComm
       voting securities (including any rights, warrants or options to acquire,

           party to the stockholder agreement.

     - Vote its shares in the same proportion as the votes cast by all holders
       of post-merger CoreComm voting securities other than the parties to this
       agreement and any affiliates and associates of post-merger CoreComm with
       respect to the applicable matter, or, in the event of a proposed change
       of control transaction, in the manner recommended to the stockholders by
       the post-merger CoreComm board of directors.

     - Not deposit any voting securities in a voting trust or subject any voting

     - Not offer, sell, assign, pledge, encumber or dispose of or transfer any
       shares of post-merger CoreComm common stock prior to nine months after
       the date of the closing of the Voyager merger, except that the common

       institution that agrees to be similarly restricted.

     - Not offer, sell, assign, pledge, encumber or dispose of or transfer any

<PAGE>   172

or beneficially) at least 7.5% of the issued and outstanding post-merger
CoreComm common stock.

THE REGISTRATION RIGHTS AGREEMENT

     In connection with the Voyager merger, post-merger CoreComm and the
principal stockholders of Voyager will enter into a registration rights
agreement. Under the registration rights agreement, the principal stockholders
of Voyager will be granted various registration rights with respect to
post-merger CoreComm common shares issued to them in connection with the Voyager
merger.

     - Demand Registration Rights.   The holders of at least 43.5% of the then
       outstanding post-merger CoreComm common stock covered by the registration
       rights agreement, at any time on or after six months from the date of the
       closing of the Voyager merger, have the right to demand that post-merger
       CoreComm register all or part of their registrable shares of common
       stock. The following conditions must be met to trigger this registration
       obligation:

         - post-merger CoreComm is not required to effect more than one demand
           registration; and

         - the number of shares of post-merger CoreComm common stock proposed to
           be registered by these stockholders shall not be less that 1,500,000
           shares, subject to adjustment.

      Post-merger CoreComm's obligation to file a demand registration statement
      is subject to reasonable and customary delays due to post-merger
      CoreComm's intentions or activities or the effectiveness of another
      stockholder's registration statement.

     - Piggyback Registration Rights.   The principal stockholders of Voyager
       can request to have their shares of registrable common stock registered
       if, at any time prior to the second anniversary of the registration
       rights agreement, post-merger CoreComm files a registration statement to
       register any of its common shares for its own account. The following
       conditions must be met to trigger this registration obligation:

         - The number of shares that can be registered at any one time may be
           limited by any underwriter, if, in its opinion, the amount of common
           stock required to be included in the registration statement exceeds
           the amount that can be sold in the offering without adversely
           affecting the distribution.

         - No piggyback registration rights apply with respect to most Forms S-8
           or Forms S-4.

      The number of times the piggyback registration rights may be exercised is
      unlimited. The registration rights agreement contains restrictions on
      future grants of registration rights by post-merger CoreComm that could
      interfere with the demand rights described above.

                                       159
<PAGE>   173

     The registration rights agreement also contains customary provisions

                 THE MERGER AGREEMENT BETWEEN CORECOMM AND ATX

     The following is a brief summary of the significant provisions of the
merger agreement between CoreComm and ATX. A copy of the ATX merger agreement is
attached to and incorporated into this joint proxy statement and prospectus as
Annex B. You should read the ATX merger agreement carefully and in its entirety.

GENERAL

     The ATX merger agreement provides for a merger and amalgamation of CoreComm
with and into a newly-formed wholly-owned subsidiary, CoreComm Merger Sub Inc.,
solely in order to relocate the jurisdiction of CoreComm from Bermuda to
Delaware. In this domestication merger, each existing common share of CoreComm
(and the accompanying right to acquire one one-hundredth of a share of
CoreComm's Series A Junior Preferred Stock under CoreComm's shareholders rights
plan) will be exchanged for one share of common stock of the subsidiary.

     Immediately following the completion of the domestication merger, the newly
reincorporated CoreComm will merge directly into ATX, and ATX will be renamed
"CoreComm Limited" (also referred to as post-merger CoreComm).

     Simultaneously with the ATX merger, ATX will be recapitalized by having the
existing ATX stockholders exchange all of the issued and outstanding shares of
ATX common stock, par value $0.01 per share, for the consideration outlined
below.

     In the ATX merger, each issued and outstanding common share of CoreComm
will be exchanged for one share of post-merger CoreComm common stock.

     In the recapitalization, all of the shares of ATX common stock will be
exchanged for the following aggregate consideration:

     - $500.0 million of post-merger CoreComm common stock (based on the value
       of CoreComm common shares at the time of signing, and subject to
       adjustment and a collar, as discussed below);

     - $250.0 million of post-merger CoreComm convertible preferred stock, (for
       further description of the terms and provisions of the convertible
       preferred stock, please read the section of this joint proxy statement
       and prospectus entitled "Description of the Capital Stock of post-merger
       CoreComm"); and

     - $150.0 million in cash, of which up to $110 million may be paid in the
       form of three-year senior notes, at CoreComm's option, plus up to $9
       million of additional three-year senior notes, if any three-year senior
       notes are actually issued.

                                       160
<PAGE>   174

     The number of shares of post-merger CoreComm common stock to be issued in
the ATX recapitalization is initially set assuming the price per share (based on
the price per share of the CoreComm common shares during the ten trading day
period before the signing of the ATX merger agreement) will equal $40.328,
otherwise known as the base amount. This will result in the issuance of
approximately 12.4 million shares of post-merger CoreComm common stock. However,
if the volume weighted average trading price of CoreComm common shares during
the ten trading days prior to the closing date of the ATX merger is greater than
a specified price, known as the threshold stock price, then the number of shares
of post-merger CoreComm common stock to be issued in the recapitalization will
be adjusted such that the aggregate value of the post-merger CoreComm common
stock received by ATX stockholders, based on the ten-day average trading price,
is increased to equal the original value ($500.0 million) multiplied by a
fraction, the numerator of which is the collar stock price and the denominator
of which is the base amount. While the aggregate value of post-merger CoreComm
common stock received in the ATX recapitalization will have increased (because
the value of each share will be more than the base amount) the ATX stockholders
will receive no more than, and could receive less than, the approximately 12.4
million shares discussed above.

     The threshold stock price is determined by multiplying the base amount by
115%, with the following further adjustments:

     - if the closing of the ATX merger has not occurred on or prior to July 15,
       2000; and

     - after the date of the ATX merger agreement, CoreComm has engaged in a
       transaction that would:

         - require the approval of the CoreComm shareholders; or

         - require CoreComm to include the information relating to the
           transaction in the pro forma financial statements required for the
           registration statement of which this proxy statement is a part; or

         - require CoreComm to materially amend the pro forma financial
           statements; and

     - all closing conditions to the ATX merger agreement have been satisfied or
       are capable of being satisfied with reasonable best efforts, other than
       the granting of all regulatory consents and/or the effectiveness of the
       registration statement, because of the engagement by CoreComm in a
       transaction other than the ATX merger,

then, commencing on the trigger date, which is the later to occur of

     - July 16, 2000 and

     - the first business day after which the circumstances set forth in the
       third bullet point in the prior paragraph are present,

the 115% will be increased as follows: 2.5 percentage points on the trigger
date, and an additional five percentage points per each 31-day period beginning
on the sixteenth

                                       161
<PAGE>   175

calendar day following the trigger date. Any increase of that nature will be
prorated during each such 31-day period.

     In addition, the base amount of $40.328 will also be adjusted:

     - upon any reclassification, recapitalization, stock split, reverse stock
       split, combination or exchange of shares or any dividend payable in
       CoreComm common shares so that the existing ATX stockholders achieve the
       same economic effect originally contemplated in the ATX merger agreement;
       and

     - upon any distribution to CoreComm shareholders of, or rights or warrants
       for, capital stock (other than common stock), debt, other assets (other
       than cash dividends) or by reducing the base amount in a manner designed
       to reflect the decrease in value achieved by such distribution.

     The ATX merger agreement provides that CoreComm, at its election, may cause
up to $110 million of the $150 million payable in cash to be paid in the form of
three-year senior notes. If any three-year senior notes are issued, the
stockholders of ATX will be entitled to receive an additional amount in the form
of three-year senior notes. This additional amount will not exceed $9 million
and will be reduced proportionately to the extent that less than $110 million of
the cash consideration that could be paid in three-year senior notes is actually
paid in three-year senior notes.

     The features of these three-year senior notes are as follows:

     - The notes will mature three years after the closing of the ATX merger.

     - The interest rate will be set at 7% per year. Interest will be paid in
       cash or common stock, at post-merger CoreComm's election, on a
       semi-annual basis. If interest is paid in the form of common stock,
       either the issuance of that common stock must be covered by an effective
       registration statement under the Securities Act or a registration
       statement under the Securities Act covering the resale of that common
       stock must be effective as of the date of the interest payment.

     - Post-merger CoreComm is permitted to prepay the notes at any time without
       penalty or premium.

     - The notes must generally be repaid out of the net proceeds on any future
       equity or debt financing, excluding certain contemplated financings and
       the refinancing of the same. Specifically, 50% of all those net proceeds
       must be applied to repay the notes until $100 million in aggregate
       principal amount of notes is repaid. After $100 million in aggregate
       principal amount of notes is repaid, 100% of those net proceeds must be
       applied to repay the notes.

     - If $110 million of the cash consideration is paid in the form of notes,
       post-merger CoreComm must make the following mandatory repayments:

       - $2.3 million on January 1, 2001;

       - $700,000 on the six-month anniversary of the closing of the ATX merger;

       - $3 million on January 1, 2002; and

                                       162
<PAGE>   176

       - $3 million on January 1, 2003.

       If less than $110 million of the cash consideration is paid in the form
       of notes, the above-described repayments will be reduced proportionately.

       If the principal amount of notes issued has been reduced, other than by
       payment of the above amounts, the required repayments set forth above
       shall be reduced proportionately and the excess shall be forgiven.

     - Post-merger CoreComm will be entitled to satisfy in full all of its
       obligations under the notes by paying less than the full outstanding
       principal amount of the notes if:

       - On or before December 31, 2001, post-merger CoreComm pays an amount
         equal to the excess of the outstanding aggregate principal amount of
         the notes (plus any accrued interest) over $6 million; or

       - On or before December 31, 2002, post-merger CoreComm pays an amount
         equal to the excess of the outstanding aggregate principal amount of
         the notes (plus any accrued interest) over $3 million.

     - The notes will rank senior to all subordinated indebtedness and equal
       with all other senior indebtedness. Post-merger CoreComm will not be
       permitted to incur secured indebtedness, other than vendor financing and
       certain other currently contemplated financing, and any refinancings of
       those financings, unless it secures the notes equally, to the extent that
       the amount of secured indebtedness is less than or equal to the amount
       repaid on the notes; and to the extent that the amount of that secured
       indebtedness is greater than the amount repaid on the notes, the notes
       must be given a security interest that is superior to that of the secured
       indebtedness.

     The ATX merger agreement also provides that the aggregate consideration to
be received by the existing ATX stockholders:

     - is to be reduced or increased, respectively, by the amount that working
       capital of ATX at closing is greater or less than $0 on the earlier of
       the closing date and August 31, 2000;

     - is to be reduced by the amount of debt of ATX at the earlier of the
       closing date and August 31, 2000;

     - is to be reduced or increased to the extent ATX has made less than or
       more than approximately $5.8 million of capital expenditures between
       January 1 to July 31, 2000, with any increase to be limited to $1.5
       million; and

     - is to be reduced to the extent that ATX makes specified distributions or
       payments to its stockholders or is required to make transaction-related
       payments, including investment banking and professional fees, after
       August 31, 2000.

     The ATX merger agreement requires the ATX stockholders to satisfy ATX's
obligations to ATX employees who have rights under the ATX Phantom Unit Plan. It
is currently expected that in satisfying those obligations, approximately
930,000 shares of
                                       163
<PAGE>   177

post-merger CoreComm common stock that would otherwise be issued to the ATX
stockholders in the ATX recapitalization will be delivered directly to those ATX
employees in satisfaction of their rights under the ATX Phantom Unit Plan, which
will be terminated at the time of the ATX recapitalization.

     No certificates or scrip representing fractional shares of post-merger
CoreComm common stock will be issued upon surrender for exchange of holders of
CoreComm certificates. Cash will be issued instead of fractional shares of
post-merger CoreComm common stock upon surrender of that certificate, along with
any dividends or other distributions to which the holder is entitled, in each
case without interest and less any required withholding taxes.

     The ATX merger and the recapitalization are intended to qualify as
exchanges and as tax-free reorganizations for federal income tax purposes.

     Dissenters' rights of appraisal are not available to CoreComm's
shareholders in connection with the ATX merger. However, dissenters' rights of
appraisal are available to CoreComm's shareholders in connection with the
domestication merger.

     The ATX merger agreement is governed by the laws of the State of Delaware
without regard to conflicts of law rules.

     Except as otherwise specified in the ATX merger agreement or agreed by the
parties, each party will pay all fees and expenses it incurs in the ATX merger.

POST CLOSING CAPITALIZATION

     Following the ATX recapitalization and the ATX merger, post-merger CoreComm
will have approximately 52.5 million shares of common stock outstanding.
CoreComm's pre-merger shareholders will own approximately 76.4% of the total and
ATX's current shareholders will own approximately 23.6% of the total.


     Assuming that the average trading price of CoreComm common shares is $12.00
and the closing trading price of CoreComm common shares is $12.00 on the trading
day prior to completing the Voyager merger, following the Voyager merger and the
ATX merger, post-merger CoreComm will have approximately 68.1 million shares of
the common stock outstanding, CoreComm's current shareholders will own
approximately 59.0% of the total, ATX's current stockholders will own
approximately 18.2% of the total and Voyager's current stockholders will own
approximately 22.8% of the total.



     All of the percentages calculated above assume that Voyager does not notify
CoreComm that it intends to terminate the Voyager merger agreement, assume that
the Voyager merger agreement is not terminated, assume that the stock to be
received by Voyager stockholders will represent 80% of the total value of the
Voyager stockholders' merger consideration and do not take into account the
exercise of any outstanding stock options or warrants or the conversion of any
convertible securities that would result in the issuance of additional common
equity of CoreComm, Voyager or ATX. For more information about how the Voyager
merger will affect the capitalization of post-merger

CoreComm and Voyager -- Post-Closing Capitalization."

EFFECTIVE TIME OF THE MERGER

     The ATX merger will be completed upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware. The parties believe this
will occur at the same time as the closing, which, unless the parties otherwise
agree, will occur on the second business day immediately following the day on
which the last of the conditions to closing are fulfilled or waived.

EXCHANGE OF CERTIFICATES

     Once the ATX merger is complete, ATX will deposit with the exchange agent
for the ATX merger, the certificates representing the shares of post-merger
CoreComm common stock and cash issuable under the ATX merger (and cash instead
of fractional shares) in exchange for outstanding CoreComm common shares.

     All shares of post-merger CoreComm common stock issued upon the surrender
for exchange of CoreComm common shares will be issued in full satisfaction of
all rights to CoreComm common shares, except for ATX's obligation to pay any
dividends or make any other distributions with a record date prior to the date
the ATX merger is effected which may have been declared or made by CoreComm on
or prior to March 9, 2000 and that remain unpaid.

     As soon as possible after the ATX merger, the exchange agent will mail a
letter of transmittal and instructions to CoreComm shareholders, explaining how
to surrender CoreComm common shares to the exchange agent. Upon surrender of
CoreComm certificates to the exchange agent, CoreComm shareholders will be
entitled to receive a certificate representing the number of whole shares of
post-merger CoreComm common stock, and cash instead of any fractional share.

THE REGISTRATION RIGHTS AGREEMENT

     In connection with the ATX merger, post-merger CoreComm and the existing

registration rights with respect to:

     - the shares of post-merger CoreComm common stock issued to them in the ATX
       recapitalization;

     - the shares of convertible preferred stock issued to them in the
       recapitalization; and

     - any shares of post-merger CoreComm common stock issued to them upon
       conversion of, or as payment of dividends on, or in exchange for shares
       of the convertible preferred stock or in respect of interest payments
       under the three-year senior notes issued to the ATX stockholders in
       connection with the ATX recapitalization.

                                       177
<PAGE>   191

     Shelf Registration Rights.   Post-merger CoreComm will be required to file
and keep in place until all shares issued to the ATX stockholders in the ATX
recapitalization may be sold in accordance with Rule 144 under the Securities
Act, a shelf registration statement covering the resale of all of the securities
identified above. Only one underwritten offering will be permitted to be made
using the shares registered under the shelf registration.

     Demand Registration Rights.   At any time on or after nine months from the
date of closing of the ATX merger, the holders of at least 10% of the
outstanding shares of common stock subject to the agreement will have the right,
exercisable only once, to demand that post-merger CoreComm register all or part
of their registrable shares of common stock under the Securities Act, provided
that the number of shares of common stock proposed to be registered may not be
less than 1,500,000 shares as of the date of the request (subject to appropriate
adjustments).

     In addition, at any time after the date the registration rights agreement
is executed, the holders of at least 25% of the outstanding shares of
convertible preferred stock have the right, exercisable only once, to demand
that post-merger CoreComm register all or part of their shares of convertible
preferred stock under the Securities Act. The following conditions must be met
to trigger this registration obligation:

       registration of preferred stock; and

     - the stated value of the preferred shares to be registered may not be less
       than $80,000,000 as of the date of the request.

     The requirement to file a demand registration statement is subject to
reasonable and customary delays due to post-merger CoreComm's intentions or
activities or effectiveness of another stockholder's registration statement.

     Piggyback Registration Rights.   The existing stockholders of ATX can
request that their shares of registrable common stock be registered under the
Securities Act if, at any time prior to the fourth anniversary of the
registration rights agreement, post-merger CoreComm files a registration
statement to register any of its common stock for its own account or for the
account of any of its stockholders. The following conditions must be met to
trigger this registration obligation:

     - The number of shares that can be registered at any one time may be
       limited by any underwriters; and

     - No piggyback registration rights apply with respect to most registration
       statements utilizing Forms S-8 or Forms S-4.

     The registration rights agreement contains restrictions on future grants of
registration rights by post-merger CoreComm that could interfere with the demand
rights described above.

     The registration rights agreement also contains customary provisions
regarding the payment of expenses by post-merger CoreComm and mutual
indemnification agreements between post-merger CoreComm and the securityholders
who are parties to the registration rights agreement for security law
violations.

                       THE DOMESTICATION MERGER AGREEMENT

     The following is a brief summary of the significant terms and provisions of
the amalgamation and merger agreement between CoreComm and its wholly-owned
subsidiary, CoreComm Merger Sub, Inc. A full copy of the domestication and
amalgamation merger agreement is attached as Annex C to and incorporated into
this joint proxy statement and prospectus. We encourage you to read the
domestication merger agreement carefully and in its entirety.

     The domestication merger agreement provides for the amalgamation and merger
of CoreComm into CoreComm Merger Sub, Inc. The domestication merger will occur
immediately prior to the earlier of the closing of (a) the ATX merger or (b) the
Voyager merger. As a result of the domestication merger CoreComm will cease to
exist as a Bermuda company. Please refer to the section entitled "The Merger
Transactions -- The Domestication Merger" for more information.

     The certificate of incorporation and by-laws of CoreComm Merger Sub, Inc.

value $0.01 per share, of CoreComm, together with each accompanying right to
acquire one one-hundredth of a share of CoreComm Series A Junior Participating
Preferred Stock, shall be canceled and exchanged for one share of CoreComm
Merger Sub, Inc. common stock. Each share of CoreComm Merger Sub, Inc. held by
CoreComm will be cancelled for no consideration.

     Appraisal Rights.   Under the domestication amalgamation and merger
agreement, the shares of CoreComm owned by a dissenting CoreComm shareholder who
has applied for appraisal will be canceled with effect at the time of the
domestication merger in consideration for the right to receive such
consideration as may be payable pursuant to Bermuda law to the dissenting
shareholders upon completion of the domestication
                                       179

merger. In the event that a dissenting shareholder fails to perfect, effectively
withdraws or otherwise loses any right to appraisal and payment under Section
106 of the Companies Act, that dissenting shareholder will no longer have any
right to appraisal thereunder and will be entitled to elect to receive the
merger consideration.

     Conditions.   Each of CoreComm's and CoreComm Merger Sub, Inc.'s obligation
to complete the domestication merger is subject to the certain completion of

                           CERTAIN RELATIONSHIPS AND
                       RELATED TRANSACTIONS FOR CORECOMM

CONFLICTS OF INTEREST

     Many of CoreComm's officers and directors are also officers and directors
of other companies in post-merger CoreComm's industry and some are employed by
CoreComm's affiliates. Their duties to these companies may require significant
amounts of their attention and may also present conflicts of interest, either of
which may impede their ability to make decisions for post-merger CoreComm.
Please refer to the section entitled "Risk Factors."

SERVICES PROVIDED BY NTL INCORPORATED

     NTL, an historical affiliate of CoreComm, shares some resources with
CoreComm, such as office space and employees. NTL will provide post-merger
CoreComm and its subsidiaries with management, financial, legal and technical
services, access to office space and equipment and use of supplies. Amounts
charged to post-merger CoreComm by NTL will consist of salaries and direct costs
allocated to post-merger CoreComm where identifiable, and a percentage of the
portion of NTL's corporate overhead which cannot be specifically allocated to
NTL (which will be agreed upon by post-merger CoreComm's board of directors and
the board of directors of NTL). It is not practicable to determine the amounts
of these expenses that would be incurred if post-merger CoreComm were to operate
as an unaffiliated entity. In our opinion, this allocation method is reasonable.
For the year ended December 31, 1999 and for the period from April 1, 1998 (date
operations commenced) to December 31, 1998, NTL charged CoreComm $2,330,000 and
$313,000, respectively.

     In 1998, the percentage of NTL's non-allocated overhead that was charged to
CoreComm was 30 percent. This percentage was increased to 50% because two other
companies that had been sharing these expenses have been sold.

OTHER SERVICES

     Through CoreComm's subsidiary, CoreComm Newco, Inc., CoreComm currently
provides billing and software development services to subsidiaries of NTL, and
historically provided such services to Cellular Communications of Puerto Rico,
Inc., the company from which CoreComm was spun-off in 1998. We believe that
these transactions are priced on an arm's length basis. General and
administrative expenses were reduced by $800,000, $275,000, $138,000 and
$217,000 for the year ended December 31, 1999, the period from April 1, 1998
(date operations commenced) to December 31, 1998, the period from January 1,
1998 to May 31, 1998, and the year ended December 31, 1997, respectively, as a
result of these charges.

             CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS FOR ATX

ATX PROPERTIES AND FACILITIES

     ATX's headquarters and executive offices and primary technical operations
facility are leased from entities controlled by Michael Karp, the Chief
Executive Officer and the majority stockholder of ATX. ATX currently pays
approximately $1 million per year in rent for its headquarters/executive offices
and approximately $450,000 per year in rent for its primary technical operations
facility. The lease for ATX's primary technical operations facility currently
expires in December 2002. In connection with the ATX merger, these leases are
expected to be modified to reflect provisions found in arm's length negotiations
for such arrangements, including, without limitation:

     - the landlord will be required to give consent to a reasonable sublease,
       and will be entitled to all profits from that sublease;

     - there will be a standard recapture right;

     - there will be a standard non-disturbance clause;

     - post-merger CoreComm will no longer be obligated to share facilities,
       employees and/or supplies with the landlord;

     - existing provisions regarding the purchase of telecommunications services
       by landlord or other tenants from ATX/post-merger CoreComm will be
       eliminated; and

     - existing arrangements granting the landlord a percentage of
       ATX's/post-merger CoreComm's revenues will be eliminated.

ATX 401(k) PLAN AND HEALTH BENEFIT PLANS

     Prior to July 1, 2000 ATX's 401(k) plan and ATX's health benefit plans were
joint plans with University City Housing. These plans have been amended so that
employees of University City Housing do not participate in these ATX plans. It
is expected that post-merger CoreComm will adopt CoreComm's existing plans and
ATX's employees will be entitled to participate in those plans instead of the
existing ATX plans.

ATX LIABILITY INSURANCE PLANS

     ATX's liability insurance plans are held jointly with University City
Housing. In connection with the ATX merger, each of ATX's liability insurance
plans will be amended so that University City Housing will not be entitled to
participate in these plans.

LETTERS OF CREDIT

     Michael Karp has guaranteed or secured letters of credit issued by
financial institutions on behalf of ATX. As of March 2000, the aggregate amount
of these letters of credit is approximately $667,000. In connection with the ATX
merger, arrangements will be made by CoreComm to replace the letters of credit
or otherwise relieve Mr. Karp of liability under these letters of credit.

LOANS BY ATX TO THOMAS GRAVINA AND DEBRA BURUCHIAN

     During 1999 and 2000, ATX's predecessor, two limited partnerships, made
loans to Thomas Gravina, the current Co-President and a stockholder of ATX, and
Debra Buruchian, the other current Co-President and also a stockholder of ATX,
in the aggregate principle amounts of $2,132,842.32 each. These loans have been
satisfied.

INDEBTEDNESS OF ATX TO MICHAEL KARP

     The predecessor entities of ATX were indebted to Michael Karp in the
aggregate principle amount of $3.6 million. Approximately $1.45 million of this
amount was used to fund operating expenses of ATX. The remaining $2.15 million
was used to fund acquisitions of property, plant and equipment by ATX. These
loans have been retired.

PROVISION OF SERVICES TO ATX BY UNIVERSITY CITY HOUSING

     University City Housing, an entity controlled by Michael Karp, currently
provides general accounting, cash management, tax return preparation, payroll
and human resources services to ATX. ATX pays UCH approximately 0.38% of its
gross annual receipts for providing these services. For the year ended December
31, 1999, ATX paid UCH $501,000 for providing these services. For the six months
ended June 30, 2000, ATX paid UCH $302,000 for these services.

     In connection with the ATX merger, UCH and post-merger CoreComm will enter
into a transition services agreement under which UCH will continue to provide
these services to post-merger CoreComm for a limited period of time. The
transition services agreement is more fully described in the section of this
joint proxy statement and prospectus entitled "The Merger Agreements -- The
Merger Agreement between CoreComm and ATX -- Related Agreements -- The
Transition Services Agreement."

*    NTL provides management, financial, legal and technical services to
     CoreComm. Amounts charged to CoreComm consist of salaries and direct costs
     allocated to the Company. In 1999 and 1998, NTL charged CoreComm $2,268,000
     and $313,000, respectively. It is not practicable to determine the amounts
     of these expenses that would have been incurred had CoreComm operated as an
     unaffiliated entity. However, in the opinion of management of CoreComm, the
     allocation method is reasonable. The named executives, except Ms. Flynt,
     receive salaries from NTL and spend portions of their time providing
     executive management to CoreComm.

(1) Mr. Blumenthal resigned as Chief Executive Officer in March 1998, and Mr.
    Knapp was appointed Chief Executive Officer in March 1998.

(2) Other annual compensation consists of relocation expenses of $562,775 and
    $57,900 for 1999 and 1998, respectively.

(3) 1998 option grants do not include an aggregate of 508,246 options issued to
    the named executives as a result of an adjustment to pre-existing options in
    CCPR as a consequence of the spin-off. 1999 option grants do not include an
    aggregate of 4,110,207 options issued to the named executives as replacement
    options upon the exercise or cancellation of their respective warrants or
    options, in accordance with the plan under which these warrants or options

OPTION PLANS

     Post-merger CoreComm will adopt and inherit the option plans of CoreComm.
The following disclosure relates to those plans.

     In 1998, CoreComm's board of directors adopted the CoreComm Limited 1998
Stock Option Plan and in 1999, CoreComm's board of directors adopted the
CoreComm Limited 1999 Stock Option Plan, reserving under these plans shares for
issuance to employees and directors.

     The purpose of CoreComm's stock option plan is to encourage stock ownership
by its employees and non-employee directors, and the employees and non-employee
directors of its divisions, subsidiary corporations and other affiliates, so as
to encourage its employees to continue being employed by CoreComm and to put
forth maximum efforts for the success of its business. Under CoreComm's stock
option plans, grants may be made of options to acquire shares of CoreComm's
common stock. The options may be "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code. The terms of options granted under
CoreComm's stock option plans, including provisions regarding vesting,
exercisability, exercise price and duration, are generally set by the
compensation committee of CoreComm's board of directors. In general, options
under CoreComm's plans are 20% vested at grant and vest 20% each January 1 after
they are granted, until they are fully vested.

                                       191
<PAGE>   205

     In January 1999, CoreComm, Inc., one of CoreComm's wholly-owned
subsidiaries, adopted a stock option plan. Options granted under that plan were
not to be become exercisable unless and until there was either a registered
public offering of CoreComm, Inc.'s common stock or a spin-off of CoreComm, Inc.
However, under the terms of the options granted under that plan, CoreComm
reserved the right to cancel the plan and issue new options in the parent
company, CoreComm Limited. In March 2000, the compensation and option committee
of CoreComm's board of directors approved the cancellation of the CoreComm, Inc.
plan and the issuance of options in CoreComm Limited to eligible employees of
CoreComm, which resulted in the issuance of options to purchase approximately
2.7 million shares of CoreComm Limited common stock. The strike prices of the
new grants are approximately 30% of the fair market value of our common stock on
the date of the board approval, $14.55. Eligibility for receiving the new grants
was determined by, among other things, continued employment with CoreComm.

                        COMPARISON OF STOCKHOLDER RIGHTS

       COMPARISON OF RIGHTS OF SHAREHOLDERS OF CORECOMM LIMITED (BERMUDA)
                            AND POST-MERGER CORECOMM

GENERAL

     The rights of the holders of CoreComm common stock are currently governed
by CoreComm's present memorandum of association, bye-laws and the Companies Act
1981 of Bermuda (the Companies Act). Through the domestication merger, the
Bermuda company, CoreComm Limited, will become a Delaware corporation. If only
the Voyager merger and not the ATX merger occurs, the resulting company will be
a Delaware corporation. If the ATX merger occurs (regardless of whether the
Voyager merger occurs), the resulting company will also be a Delaware
corporation but will have adopted a certificate of incorporation and by-laws
that are identical to those which would have been adopted by the resulting
company in the Voyager merger. The following summary, which does not purport to
be a complete statement of the general differences among the rights of the
stockholders, sets forth material differences between the DGCL and the Companies
Act, the new certificate of incorporation and by-laws to be adopted by
post-merger CoreComm after consummation of the domestication merger and the
Voyager and/or ATX mergers and the present memorandum of association and by-laws
of CoreComm Limited. This summary is qualified in its entirety by reference to
the full text of the DGCL and the Companies Act. For information as to how these
documents may be obtained, see the section of this joint proxy statement and
prospectus entitled "Where You Can Find More Information."

BERMUDA AND DELAWARE CORPORATE LAW

     The Bermuda Companies Act, under which CoreComm was incorporated, differs
in material respects from the provisions of the DGCL. Set forth below is a
summary of significant provisions of the Companies Act that are materially
different from the DGCL. The following statements are summaries, and do not
purport to deal with all aspects of Bermuda or Delaware law that may be relevant
to CoreComm and its shareholders and post-merger CoreComm and its stockholders.

AUTHORIZED CAPITAL STOCK

     CoreComm had, as of July 31, 2000, 75.0 million authorized common shares,
par value $0.01 per share, of which 40,161,704 were issued and outstanding and
1.0 million authorized preferred shares, par value $0.01 per share, of which
none were issued and outstanding. The new certificate of incorporation and
by-laws to be adopted by post-merger CoreComm will authorize the issuance of
200.0 million common shares, par value $0.01 per share, and 5.0 million
preferred shares, par value $0.01 per share. If the ATX merger occurs,
post-merger CoreComm will designate 250,000 preferred shares as convertible
preferred stock.

VOTING RIGHTS WITH RESPECT TO EXTRAORDINARY CORPORATE TRANSACTIONS

     Bermuda.   Bermuda law permits amalgamation between two or more Bermuda
companies (or between a Bermuda company and one or more Bermuda or foreign
companies, and, subject to any requirement of the bye-laws of any of those
companies, generally requires the approval, in the case of the amalgamation of
non-affiliated companies, of a majority vote of three-fourths of shareholders of
each of those companies present, in person or by proxy, at a meeting called for
that purpose. CoreComm's bye-laws stipulate that a simple majority of the votes
cast by the shareholders present, in person or by proxy, at the meeting is
required to approve and any amalgamation of CoreComm with any other company. A
90% vote may be required where the amalgamation amounts to a scheme or contract
under Section 102 of the Companies Act. A majority vote of shareholders is
required to increase the authorized capital of a Bermuda company, but unless an
increase is required, and unless there is any provision in the bye-laws to the
contrary, no shareholder approval is required for the issuance of shares by an
acquiring company in a share-for-share exchange, asset purchase, or, subject to
the limitations set forth below, other forms of reorganization.

     Delaware.   Approval of mergers and consolidations and of sales, leases or
exchanges of all or substantially all of the property or assets of a company,
require the approval of the holders of a majority of the outstanding shares
entitled to vote, except that no vote of the stockholders of a corporation
surviving a merger is necessary if (a) the merger does not amend the certificate
of incorporation of the corporation, (b) each outstanding share immediately
prior to the effective date of the merger is to be an identical share after the
merger, and (c) either no common stock of the corporation and no securities or
obligations convertible into common stock are to be issued in the merger, or the
common stock to be issued in the merger plus common stock initially issuable on
conversion of other securities issued in the merger does not exceed 20% of the
common stock of the corporation immediately before the effective date of the
merger.

DISSENTERS' RIGHTS

     Bermuda.   Under Bermuda law, a dissenting shareholder of a company
participating in extraordinary corporate transactions may, under varying
circumstances, receive cash in the amount of the fair market value of its shares
(as determined by a court), in lieu of the consideration it would otherwise
receive in the transactions. Bermuda law generally does not condition
dissenters' rights to circumstances in which a vote of the stockholders of the
surviving company is required. Bermuda law, in general, provides for dissenters'
rights in an amalgamation between non-affiliated companies and affiliated
companies where one company is not a Bermuda company, an amendment to a
company's memorandum of association, a scheme of arrangement, or reconstruction
and certain other transactions. For a more thorough discussion of dissenters'
rights under Bermuda law, see the section of this joint proxy statement and
prospectus entitled "The Merger Transactions -- The Domestication
Merger -- Appraisal Rights."

                                       196
<PAGE>   210

     Delaware.   Stockholders are entitled to demand appraisal of their shares
in the case of mergers or consolidations, except where (a) they are stockholders
of the surviving company and the merger did not require their approval under the
DGCL, or (b) their shares are either listed on a national securities exchange or
the Nasdaq Stock Market or held of record by more than 2,000 stockholders.
Appraisal rights are available in either (a) or (b) above, however, if the
stockholders are required by the terms of the merger or consolidation to accept
any consideration other than (w) shares of the corporation surviving or
resulting from the merger or consolidation, (x) shares of another company that
are either listed on a national securities exchange or held of record by more
than 2,000 stockholders, (y) cash in lieu of fractional shares, or (z) any
combination of the above. Appraisal rights are not available in the case of a
sale, lease, exchange or other disposition by a company of all or substantially
all of its property and assets.

DERIVATIVE SUITS

     Bermuda.   In the event of extraordinary corporate transactions an action
can be brought by minority shareholders, on behalf of a Bermuda company, seeking
to enforce a right of action of that company. Under Bermuda law, a shareholder
may commence a derivative action in the name of the company to remedy a wrong
done to the company only (a) where the act complained of is alleged to be beyond
the corporate capacity of the company or illegal, (b) where the act complained
of constitutes a fraud against the minority shareholders by those controlling
the company, (c) where an act requires approval by a greater percentage of the
company's shareholders than actually approved it or (d) where the act infringes
the personal rights of an individual shareholder. However, a derivative action
will not be permitted where there is an alternative action available that would
provide an adequate remedy. Any property or damages recovered by derivative
action go to the company, not to the plaintiff shareholders. The Companies Act
enables a shareholder who complains that the affairs of a company are being or
have been conducted in a manner oppressive or prejudicial to some part of the
shareholders, including itself, to petition the court. The Court will consider
the interests of the shareholders in determining whether or not the company
should be dissolved, with its assets distributed and may make any order it
thinks fit. The Companies Act also provides that a company may be wound up by
the court if the court is of the opinion that minority shareholders need relief
from the oppressive conduct of the majority.

     Except as mentioned above, claims against a Bermuda company by its
shareholders must be based on the common law of Bermuda. A statutory right of
action is conferred on subscribers to shares of a Bermuda company against
persons (including directors and officers) responsible for the issue of a
prospectus in respect of damage suffered by reason of an untrue statement
contained in the prospectus, but this confers no right of action against the
Bermuda company itself. In addition, a Bermuda company itself (as opposed to its
shareholders) may take action against its officers (including directors) for
breach of their statutory and fiduciary duty to act honestly and in good faith
with a view to the best interests of the company.

     Delaware.   Derivative actions may be brought in Delaware by a stockholder
on behalf of, and for the benefit of, the corporation. The DGCL provides that a
stockholder
                                       197
<PAGE>   211

must state in the complaint that it was a stockholder of the corporation at the
time of the transaction it is complaining about. A stockholder may not sue
derivatively unless it first makes demand on the corporation that it bring suit
and the demand has been refused, unless it is shown that the demand would have
been futile. No suit may be brought against any officer, director, or
stockholder for any debt of a corporation for which it is an officer, director,
or stockholder, until judgment and execution for the action is obtained against
the corporation.

SPECIAL MEETINGS OF STOCKHOLDERS

     Bermuda.   Under Bermuda law, a special meeting of shareholders may be
convened by the shareholders at any time and must be convened upon the presence
of shareholders holding not less than one-tenth of the paid-in capital of a
company carrying the right to vote at general meetings.

     Delaware.   Stockholders generally do not have the right to call meetings
of stockholders unless the right is granted in the certificate of incorporation
or bylaws. However, if a company fails to hold its annual meeting within a
period of 30 days after the date designated for the meeting, or if no date has
been designated for a period of 13 months after its last annual meeting, the
Delaware Court of Chancery may order a meeting to be held upon the formal
request of a stockholder or director. The new by-laws to be adopted by
post-merger CoreComm will state that the board of directors of post-merger
CoreComm, the Chairman or the President may call a special meeting of
stockholders but that a special meeting of stockholders may not be called by any
other person or persons, including the stockholders of post-merger CoreComm.

AMENDMENTS TO CHARTER

     Bermuda.   Amendments to the memorandum of association and bye-laws of a
Bermuda company must be submitted to a general meeting of the shareholders and
will be effective only to the extent approved by the shareholders at such
meeting. If the holders of not less than 20% in par value of the shares do not
support the amendments they may apply to a court to annul the amendment within
twenty-one days of the resolution amending the memorandum. The present by-laws
require a 66 2/3% vote to amend some of their provisions.

     Delaware.   Amendments to the certificate of incorporation require the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote on that matter; except that if the certificate of incorporation requires
the vote of a greater number or proportion of the holders of any class of stock
than is required by Delaware law with respect to any matter, the provision of
the certificate of incorporation may not be amended, altered or repealed except
by the greater vote required. In addition, the holders of the outstanding shares
of a class are entitled to vote as a class on any amendment to the certificate
of incorporation, whether or not they are entitled to vote on that matter by the
certificate of incorporation, if the amendment would increase or decrease the
aggregate number of authorized shares of the class, increase or decrease the par
value of the shares of the class or alter or change the powers, preferences or
special

                                       198
<PAGE>   212

rights of the class so as to affect them adversely. The new certificate of
incorporation and new by-laws will require a 66 2/3% vote to amend some of its
provisions.

ANTI-TAKEOVER STATUTES

     Bermuda.   Bermuda does not currently have a tender offer statute. However,
the Companies Act provides that where an offer is made for shares in a company
by another company and, within four months of the offer, the holders of not less
than 90% in value of the shares that are the subject of the offer accept it, the
offeror may by notice, given within two months after the expiration of the four
months, require that dissenting shareholders transfer their shares under the
terms of the offer. Dissenting shareholders may apply to a court within one
month of the notice objecting to the transfer, and the court may give any order
as it thinks fit. The Companies Act also provides that the holders of not less
than 95% of the shares of any class of shares in a company may give notice to
the remaining shareholders or class of shareholders of the intention to acquire
their shares on the terms set out in the notice. Recipients of the notice have a
right to apply to the Bermuda courts for an appraisal.

     Delaware.   Generally, Section 203 of the DGCL prohibits a publicly held
Delaware company from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless (a) prior to such
time, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder, (b) upon completion of the transaction that resulted in
the stockholder becoming an interested stockholder, the interested stockholder
owns at least 85% of the outstanding voting stock (with certain exclusions), or
(c) on or after such date the business combination is approved by the board of
directors and by the affirmative vote of at least 66 2/3% of the outstanding
voting shares that is not owned by the interested stockholder. An "interested
stockholder" is a person who, together with affiliates or associates, owns 15%
or more of the corporation's voting stock.

LIMITATIONS ON DIRECTOR LIABILITY

     Bermuda.   Under Bermuda law, a director must observe the statutory duty of
care, which requires such director to act honestly and in good faith with a view
to the best interests of a company and exercise the care, diligence and skill
that a reasonably prudent person would exercise in comparable circumstances.
Bermuda law renders void any provision in the bye-laws or any contract between a
company and any such director exempting it from or indemnifying it against any
liability for fraud or dishonesty of which it may be guilty in relation to that
company.

     Delaware.   Under Delaware law, a company may include in its certificate of
incorporation, a provision eliminating or limiting the liability of a director
to the corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, provided that a company may not eliminate or limit
the liability of a director (a) for any breach of the director's duty of loyalty
to the corporation or its stockholders,

                                       199
<PAGE>   213

(b) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (c) acts concerning unlawful payments
of dividends or stock purchases or redemptions under Section 174 of the DGCL, or
(d) for any transactions from which a director derived an improper personal
benefit. The new certificate of incorporation will contain some provisions which
will limit the liability of post-merger CoreComm's board of directors as
permitted under Delaware law.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Bermuda.   Under Bermuda law, a company is permitted to indemnify its
officers and directors, out of the funds of the company, against any liability
incurred by them in defending any proceedings, whether civil or criminal, in
which judgment is given in their favor, or in which they are acquitted, or in
connection with any application under relevant Bermuda legislation in which
relief from liability is granted to them by the court. The present by-laws
contain provisions regarding the indemnification of the officers and directors
of CoreComm as permitted under Bermuda law.

     Delaware.   Under Delaware law, a company is permitted to indemnify its
officers, directors and certain others against any liability or expenses
incurred in any civil, criminal, administrative or investigative proceeding if
they acted in good faith and in a manner they reasonably believed to be in or
not opposed to the best interests of the corporation and, with respect to any
criminal proceeding, had no reasonable cause to believe their conduct was
unlawful, except that in any action brought by or in the right of the
corporation, such indemnification may be made only for expenses (not judgments
or amounts paid in settlement) and may not be made even for expenses if the
officer, director or other person is adjudged liable to the corporation (unless
otherwise determined by the court). In addition, under Delaware law, to the
extent that a director or officer of a company has been successful on the merits
or otherwise in defense of any proceeding referred to above, it must be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by that party. The new by-laws will contain provisions relating to the
indemnification of post-merger CoreComm's officers and directors.

INSPECTION OF BOOKS AND RECORDS; SHAREHOLDER LISTS

     Bermuda.   Bermuda law provides the general public with a right of
inspection of a Bermuda company's public documents at the office of the
Registrar of Companies in Bermuda, and provides a Bermuda company's shareholders
with a right of inspection of the company's bye-laws, minutes of general
(shareholder) meetings, and audited financial statements. The register of
shareholders is also open to inspection by shareholders free of charge and, upon
payment of a small fee, by any other person. A Bermuda company is required to
maintain its share register in Bermuda but may, in certain circumstances,
establish a branch register outside of Bermuda. A Bermuda company is required to
keep at its registered office a register of its directors and officers that is
open for inspection by members of the public without charge. Bermuda law does
not, however, provide a general right for shareholders to inspect or obtain
copies of any other corporate records.

                                       200
<PAGE>   214

     Delaware.   Any stockholder of record, in person or by attorney or other
agents, upon written demand under oath stating the purpose of the demand, has
the right during the corporation's usual hours for business to inspect, for any
proper purpose, the corporation's stock ledger, a list of its stockholders, and
its other books and records, and to make copies or extracts from these
documents.

PREEMPTIVE RIGHTS

     Bermuda.   Under Bermuda law, no shareholder has a preemptive right to
subscribe for additional issues of a company's shares unless, and to the extent
that, the right is expressly granted to the shareholder under the bye-laws of a
company or under any contract between the shareholder and the company.

     Delaware.   Under Delaware law, no stockholder has a preemptive right to
subscribe to additional issues of a corporation's stock unless, and to the
extent that, the right is expressly granted to the stockholder in the
corporation's certificate of incorporation. The new certificate of incorporation
will not provide for preemptive rights.

DIVIDENDS

     Bermuda.   Bermuda law permits payment of dividends and distributions of
contributed surplus by a company unless the company, after the payment is made,
would be unable to pay its liabilities as they become due, or the realizable
value of the company's assets would be less, as a result of the payment, than
the aggregate of its liabilities and its issued share capital and share premium
accounts. The excess of the consideration paid on the issuance of shares over
the aggregate par value of the shares must (except in certain limited
circumstances) be credited to a share premium account. Share premium may be
distributed in limited circumstances, for example to pay up unissued shares that
may be distributed to shareholders in proportion to their holdings, but is
otherwise subject to limitation.

     Delaware.   Delaware law generally allows dividends to be paid out of
surplus of the corporation or out of the net profits of the corporation for the
current fiscal year and/or the prior fiscal year. No dividends may be paid if
they would result in the capital of the corporation being less than the capital
represented by the preferred shares of the corporation.

VOTING RIGHTS AND QUORUM REQUIREMENTS

     Bermuda.   Under Bermuda law, in the absence of any other agreement to the
contrary, the voting rights of shareholders are regulated by the present
by-laws. The by-laws now in place for CoreComm specify that at least two
shareholders present in person or by proxy and entitled to vote representing the
holders of more than 50% of the issued shares shall be a quorum for all purposes
which is required to transact business. Under the present by-laws, any
shareholder of CoreComm who is present at a meeting may vote in person or by
proxy and each shareholder is entitled to one vote for each CoreComm share
owned.

                                       201
<PAGE>   215

     Delaware.   Under the DGCL and the new certificate of incorporation to be
adopted by post-merger CoreComm, each holder of common shares will be entitled
to one vote per share. A quorum will be satisfied when enough holders of the
capital stock issued and outstanding and entitled to vote are present at an
annual or special meeting, in person or by proxy, to cast a majority of the
votes entitled to be cast by the stockholders. The new by-laws will provide that
all matters which require a vote by the stockholders may (but need not) be by
written ballot, and this determination will be made at the discretion of
post-merger CoreComm's board of directors or the officer presiding at the
meeting.

NUMBER AND QUALIFICATIONS OF DIRECTORS; SIZE OF BOARD

     Bermuda.   Under Bermuda law, the minimum number of directors on the board
of directors of a company is two, although the minimum number of directors may
be set higher and the maximum number of directors may also be set in accordance
with the bye-laws of the company. The exact number of directors is usually fixed
by the shareholders in general meeting. Only the shareholders may increase or
decrease the number of director seats last approved by the shareholders.

     The present by-laws of CoreComm set forth that the directors shall be
divided into three classes, designated Class I, Class II and Class III and each
class shall consist, as nearly as may be possible, of one-third of the total
number of directors constituting the entire board. The term of the initial Class
I directors shall terminate on the date of the year 2000 annual meeting; the
term of the initial Class II Directors shall terminate on the date of the year
2001 annual meeting and the terms of the initial Class III directors shall
terminate on the date of the year 2002 annual meeting of shareholders. At each
annual meeting beginning in 2000, successors to the class of directors whose
term expires at that annual meeting shall be elected for a three-year term. If
the number of directors is changed, any increase or decrease shall be
apportioned among the classes so as to maintain the number of directors in each
class as nearly equal as possible.

     The present by-laws of CoreComm set forth that the minimum number of
directors shall be not less than three (3) and the maximum number of directors
shall be fifteen (15). The current size of the board of directors of CoreComm is
currently fixed at 8. The current by-laws also provide that whenever the holders
of any one or more classes or series of preference shares issued by CoreComm
shall have the right to elect directors at an annual or special meeting of
shareholders, the election shall be governed by the terms of resolutions adopted
by the board of directors at the time the class of preference shares is
established.

     Delaware.   Under Delaware law, the minimum number or directors is one. The
number of directors constituting the board of directors of a Delaware
corporation may be specified in the bylaws or the certificate of incorporation.
Accordingly, unless the certificate of incorporation provides otherwise, the
directors may change the number of directors constituting the board by amending
the bylaws. If the number of directors is specified in the certificate of
incorporation, then any change in the number of directors must be made through a
certificate of amendment approved by the stockholders.

                                       202
<PAGE>   216

     The number of directors for post-merger CoreComm will be set in the new
by-laws. The board of directors of post-merger CoreComm will be classified in
the same manner as the board of directors of CoreComm.

REMOVAL OF DIRECTORS

     Bermuda.   Subject to its bye-laws the shareholders of a Bermuda company
may, at a special general meeting called for the purpose, remove any director or
the entire board of directors provided that notice of the meeting will be served
on the director or directors concerned not less than fourteen days before such
meeting. Any director given notice of removal will be entitled to be heard at
the meeting. The present by-laws provide that directors may be removed from
office for cause by the affirmative vote of at least a majority of the shares
entitled to vote for the election of directors.

     Delaware.   Unless a corporation's certificate of incorporation provides
otherwise and except in the case of a classified board of directors or where
cumulative voting applies, Delaware law allows directors of a corporation to be
removed with or without cause by the vote of the holders of a majority of the
shares entitled to vote in any election of directors.

     The new certificate of incorporation to be adopted by post-merger CoreComm
will provide that directors may be removed only for cause by the affirmative
vote of the holders of at least two-thirds (66 2/3%) of the outstanding shares
of post-merger CoreComm then entitled to vote generally in the election of
directors.

    COMPARISON OF RIGHTS OF STOCKHOLDERS OF POST-MERGER CORECOMM AND VOYAGER

     The rights of Voyager stockholders are currently governed by the Delaware
General Corporation Law, or DGCL, Voyager's second amended and restated
certificate of incorporation and Voyager's by-laws. The rights of post-merger
CoreComm stockholders will be governed by the DGCL, post-merger CoreComm's
certificate of incorporation and post-merger CoreComm's by-laws. Voyager's
by-laws and second amended and restated certificate of incorporation and
post-merger CoreComm's by-laws and certificate of incorporation are also
sometimes referred to as charter documents. The following is a summary of
material differences between the rights of Voyager stockholders and the rights
of post-merger CoreComm stockholders. It is not a complete statement of the
provisions affecting, and the differences between, the rights of Voyager
stockholders and post-merger CoreComm stockholders. The summary is qualified in
its entirety by reference to the DGCL, Voyager's second amended and restated
certificate of incorporation and by-laws, and post-merger CoreComm's certificate
of incorporation and by-laws.

CAPITALIZATION

     Voyager.   Voyager's current authorized capital stock is fifty million
(50,000,000) shares of common stock, par value $.0001 per share, of which
31,654,758 shares were outstanding as of July 17, 2000 and five million
(5,000,000) shares of undesignated

preferred stock, par value $.01 per share, of which no shares were outstanding
as of March 15, 2000.

     Post-merger CoreComm.   The charter documents of post-merger CoreComm will
authorize two hundred million (200,000,000) shares of common stock and five
million (5,000,000) shares of preferred stock, each common and preferred share
with a par value of $0.01 per share.

shall consist of one or more directors as fixed by the corporation's certificate
of incorporation or by-laws.

     Voyager.   The second amended and restated certificate of incorporation of
Voyager provides for a classified board of directors into three classes, as

in 2002.

     Post-merger CoreComm.   The post-merger CoreComm certificate of

constitute a quorum for the transaction of business at all meetings of the board
of directors.

     Voyager.   The Voyager by-laws provide that directors shall be elected at
the annual meeting of Voyager stockholders by the affirmative vote of a
plurality of the Voyager shares properly cast on the election of directors.

     Post-merger CoreComm.   The post-merger CoreComm by-laws will provide that
directors will be elected at the annual meeting of post-merger CoreComm
stockholders by the affirmative vote of a plurality of the post-merger CoreComm
shares voted at the meeting for the election of directors.

REMOVAL OF DIRECTORS

     Voyager.   The second amended and restated certificate of incorporation of
Voyager provides that directors may be removed from office only with cause and
only by the affirmative vote of the holders of two-thirds (66 2/3%) of the
shares then entitled to vote at an election of directors.

     Post-merger CoreComm.   The post-merger CoreComm certificate of
incorporation will provide that any or all of the directors of post-merger
CoreComm may be removed from office at any time, but only for cause and only by
the affirmative vote of the holders of two-thirds (66 2/3%) of the outstanding
shares of post-merger CoreComm then entitled to vote in the election of
directors.

FILLING VACANCIES ON THE BOARD OF DIRECTORS

     Voyager.   The Voyager by-laws provide that any vacancies in the board of
directors, however resulted, shall be filled solely by the affirmative vote of a
majority of the remaining directors then in office, even if less than a quorum
of the board of directors.

     Post-merger CoreComm.   The post-merger CoreComm certificate of
incorporation and the post-merger CoreComm by-laws will provide that any
vacancy, however resulted, may be filled only by a majority of the directors
then in office, though less than a quorum, or by a sole remaining director.

SPECIAL STOCKHOLDER MEETINGS

     Voyager.   The Voyager by-laws provide that special meetings of the Voyager
stockholders may be called only by the board of directors by a resolution
approved by the affirmative vote of a majority of the directors then in office.

<PAGE>   219

     Post-merger CoreComm.   The post-merger CoreComm certificate of
incorporation will provide that a special meeting of holders of post-merger
CoreComm common stock may be called at any time by the board of directors, the
chairman of the board or the president but may not be called by or at the
request of any other person.

     Voyager.   Voyager's second amended and restated certificate of
incorporation prohibits stockholder action by written consent in lieu of a
stockholder meeting.

     Post-merger CoreComm.   Post-merger CoreComm's certificate of incorporation
will prohibit stockholder action by written consent in lieu of a stockholder
meeting.

LIMITATION OF PERSONAL LIABILITY OF DIRECTORS AND INDEMNIFICATION

     Voyager.   Voyager's second amended and restated certificate of
incorporation provides that a director will not be personally liable to Voyager
or to its stockholders for monetary damages for breach of fiduciary duty as a
director, except, if required by law, for liability; for any breach of the
director's duty of loyalty to Voyager or its stockholders; for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law; under Section 174 of the Delaware General Corporation Law; and for any
transaction from which the director derived an improper personal benefit.
Voyager's second amended and restated certificate of incorporation provides a
right to indemnification to directors and officers of Voyager to the fullest
extent permitted by the DGCL. In addition, Voyager must indemnify any present or
former director or officer of Voyager who or any person who is or was serving at
the request of Voyager as a director, officer, employee or agent of another
corporation who has been successful on the merits or otherwise in the defense of
any claim or proceeding for expenses (including attorneys' fees) actually and
reasonably incurred. Voyager will indemnify in connection with a proceeding
initiated by a person seeking indemnification only if the proceeding was
authorized by Voyager's board of directors.

     Post-merger CoreComm.   Post-merger CoreComm's certificate of incorporation
will provide that a director will not be personally liable to post-merger
CoreComm or to its stockholders for monetary damages for breach of fiduciary
duty as a director, except, if required by law, for liability; for any breach of
the director's duty of loyalty to post-merger CoreComm or its stockholders; for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; under Section 174 of the Delaware General Corporation
Law; and for any transaction from which the director derived an improper
personal benefit. Post-merger CoreComm's certificate of incorporation will
provide a right to indemnification to directors and officers of post-merger
CoreComm to the fullest extent permitted by the Delaware General Corporation
Law. Also, the post-merger CoreComm by-laws will provide, in substance, that
each person made, or threatened to be made, a defendant or witness to any
action, suit or proceedings, whether civil, criminal or otherwise by reason of
the fact that he or she is or was serving, at the request of post-merger
CoreComm, in any capacity any other

                                       206
<PAGE>   220

corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, will be indemnified by post-merger CoreComm to the full extent
permitted by the DGCL.

DIVIDENDS

     Voyager.   Voyager's second amended and restated certificate of
incorporation provides that the board of directors, or an authorized committee
of the board of directors, may, in designating the terms of a series of
preferred stock, state the conditions upon which the holders of the series of
preferred stock shall be entitled to receive dividends. The common stockholders
shall be entitled to dividends only if the board of directors, or an authorized
committee of the board of directors, declares dividends and as may be permitted
by law.

     Post-merger CoreComm.   Post-merger CoreComm's certificate of incorporation
will provide that the board of directors may state the conditions upon which the
holders of a series of preferred stock shall be entitled to receive dividends.
Post-merger CoreComm's certificate of incorporation will also provide that the
common stockholders will be entitled to dividends as may be permitted by law.

AMENDMENTS TO CERTIFICATE OF INCORPORATION

     Voyager.   Voyager's second amended and restated certificate of
incorporation provides that the certificate of incorporation may be amended by
the affirmative vote of the majority of the outstanding shares entitled to vote
on the amendment or repeal, and the affirmative vote of the majority of the
outstanding shares of each class entitled to vote on that matter as a class, at
a meeting of stockholders called expressly for that purpose. Some provisions of
the certificate of incorporation require the affirmative vote of not less than
two-thirds (66 2/3%) of the outstanding shares entitled to vote on the
amendment, and the affirmative vote of not less than two-thirds (66 2/3%) of the
outstanding shares of each class entitled to vote on the amendment as a class.

     Post-merger CoreComm.   Post-merger CoreComm's certificate of incorporation
will provide that amendments the certificate of incorporation will generally
require majority approval of stockholders of post-merger CoreComm entitled to
vote unless a different proportion is specified in the certificate of
incorporation. Post-merger CoreComm's certificate of incorporation will also
provide that an amendment to the certificate of incorporation that would
adversely affect the rights of any holders of shares of a class or series of
stock must be approved by vote of the holders of a majority of all outstanding
shares of the class or series voting as a class in addition to the standard vote
of a majority of the outstanding stock entitled to vote on the amendment. The
post-merger CoreComm certificate of incorporation will also provide that
amendments to certain provisions of the certificate of incorporation will
require the approval of the holders of 66 2/3% of the stock entitled to vote on
the amendment.

                                       207
<PAGE>   221

AMENDMENTS TO BY-LAWS

     Voyager.   The Voyager by-laws provide that the by-laws may be amended or
repealed by the board of directors by the affirmative vote of a majority of the
directors then in office. The by-laws may also be amended or repealed at any
annual meeting, or special meeting of stockholders called for that purpose, by
the affirmative vote of at least two-thirds (66 2/3%) of the shares present in
person or represented by proxy at the meeting and entitled to vote on the
amendment or repeal, voting together as a single class. However, if the board of
directors recommends that stockholders approve an amendment or repeal at a
meeting of stockholders, that amendment or repeal shall only require the
affirmative vote of the majority of the shares present in person or represented
by proxy at the meeting and entitled to vote on the amendment or repeal, voting
together as a single class.

     Post-merger CoreComm.   Post-merger CoreComm's certificate of incorporation
will provide that the by-laws may be altered, amended or repealed, in whole or
in part, or new by-laws may be adopted by either the affirmative vote of the
holders of sixty-six and two-thirds percent (66 2/3%) of the outstanding capital
stock of post-merger CoreComm entitled to vote on that matter or by a resolution
adopted by the board of directors.

                                       208
<PAGE>   222

            DESCRIPTION OF THE CAPITAL STOCK OF POST-MERGER CORECOMM

GENERAL

     Post-merger CoreComm's authorized capital stock will consist of 200,000,000
shares of common stock, par value $0.01 per share, and 5,000,000 shares of
preferred stock, par value $0.01 per share.

POST-MERGER CORECOMM COMMON STOCK

     The holders of post-merger CoreComm's common stock will be entitled to one
vote for each share held of record on all matters submitted to a vote of
post-merger CoreComm's stockholders and do not have cumulative voting rights in
the election of directors. Holders of post-merger CoreComm common stock will be
entitled to receive proportionately dividends as may from time to time be
declared by post-merger CoreComm's board of directors out of funds legally
available for the payment of dividends. In the event of post-merger CoreComm's
liquidation, dissolution or winding up, holders of post-merger CoreComm common
stock would be entitled to share proportionately in all of post-merger
CoreComm's assets available for distribution to holders of post-merger CoreComm
common stock remaining after payment of liabilities and liquidation preference
of any outstanding post-merger CoreComm preferred stock. Holders of post-merger
CoreComm common stock will have no preemptive rights and will have no rights to
convert post-merger CoreComm common stock into any other securities, and there
will be no redemption provisions with respect to the common stock.

PREFERRED STOCK

     The by-laws of post-merger CoreComm will authorize the board of directors
to issue one or more series of preferred stock and determine, with respect to
any series rights, if any, and their qualifications, limitations or
restrictions, as are stated in resolutions adopted by the board of directors
providing for the issue of the series and as are permitted by the DGCL.

     The ability of the board of directors to issue one or more series of
preferred stock will provide increased flexibility in structuring possible
future financings and acquisitions and in meeting other corporate needs which
might arise. The authorized shares of preferred stock, as well as shares of
post-merger CoreComm common stock, will be available for issuance without
further action by post-merger CoreComm stockholders, unless such action is
required by applicable law or the rules of any stock exchange or automated
quotation system on which post-merger CoreComm securities may be listed or
applicable rules of any self-regulatory organization. If the approval of
post-merger CoreComm stockholders is not required for the issuance of shares of
preferred stock or common stock, the board of directors does not intend to seek
stockholder approval. The board of directors will make any determination to
issue the shares based on its judgment as to post-merger CoreComm's best
interests and the best interests of its stockholders. The board of directors, in
so acting, could issue preferred stock having terms that could discourage an
acquisition attempt or other transaction that some or a majority of the

                                       209
<PAGE>   223

stockholders might believe to be in their best interests or in which
stockholders might receive a premium for their shares over the then current
market price of such shares.

SPECIAL CHARTER PROVISIONS

     Post-merger CoreComm's certificate of incorporation, which post-merger
CoreComm refers to as the "charter," will contain the provisions described
below. Those charter provisions may have the effect, alone or in combination
with each other or with the existence of authorized but unissued common stock
and any series of preferred stock, of precluding or rendering more difficult a
hostile takeover, making it more difficult to remove or change the composition
of post-merger CoreComm's incumbent board of directors and its officers, being
adverse to stockholders who desire to anticipate in a tender offer and depriving
stockholders of possible opportunities to sell their shares at temporarily
higher prices.

     Classified board and filling of vacancies on the board of directors.   The
charter will provide that the directors shall be divided into three classes,
each of which shall serve a staggered three-year term, and that vacancies on
post-merger CoreComm's board of directors that may occur between annual meetings
may be filled by post-merger CoreComm's board of directors. In addition, this
provision will specify that any director elected to fill a vacancy on
post-merger CoreComm's board of directors will serve for the balance of the term
of the replaced director.

     Removal of directors.   The charter will provide that directors can be
removed only by the stockholders for cause and then only by the affirmative vote
of the holders of not less than two-thirds (66 2/3%) of post-merger CoreComm's
combined voting power.

     Voting requirement for some business combinations.   The charter will also
provide that, in addition to any affirmative vote required by law, the
affirmative vote of holders of two-thirds (66 2/3%) of post-merger CoreComm's
voting power will be necessary to approve any "business combination," as defined
below, proposed by an "interested stockholder," as defined below. The additional
voting requirements will not apply, however, if:

     - the business combination was approved by not less than a majority of the
       continuing directors;

     - a series of conditions are satisfied requiring, in summary, the
       following:

         (A) that the consideration to be paid to post-merger CoreComm's
             stockholders in the business combination must be at least equal to
             the higher of:

              (1) the highest per-share price paid by the interested stockholder
                  in acquiring any shares of common stock during the two years
                  prior to the announcement date of the business combination or
                  in the transaction in which it became an interested
                  stockholder, this date is referred to as the "determination
                  date," whichever is higher; or

              (2) the fair market value per share of common stock on the
                  announcement date or determination date, whichever is higher,
                  in either case

                                       210
<PAGE>   224

                  appropriately adjusted for any stock dividend, stock split,
                  combination of shares or similar event with non-cash
                  consideration treated similarly; and

         (B) various "procedural" requirements are complied with, including the
             consent solicitation of proxies according to the rules of the SEC
             and no decrease in regular dividends, if any, after the interested
             stockholder became an interested stockholder, except as approved by
             a majority of the continuing directors.

     An "interested stockholder" is defined as anyone who is the beneficial
owner of more than 15% of the voting power of the voting stock, other than
post-merger CoreComm and any employee stock plans sponsored by post-merger
CoreComm, and includes any person who is an assignee of or has succeeded to any
shares of voting stock in a transaction not involving a public offering that
were at any time within the prior two-year period beneficially owned by an
interested stockholder. The term "beneficial owner" includes persons directly
and indirectly owning or having the right to acquire or vote the stock.
Interested stockholders participate fully in all stockholder voting.

     A "business combination" includes the following transactions:

     - merger or consolidation of post-merger CoreComm or any subsidiary of
       post-merger CoreComm with an interested stockholder or with any other
       corporation or entity which is, or after the merger or consolidation
       would be, an affiliate of an interested stockholder;

     - the sale or other disposition by post-merger CoreComm or a subsidiary of
       post-merger CoreComm of assets having a fair market value of $5,000,000
       or more if an interested stockholder, or an affiliate of an interested
       stockholder is a party to the transaction;

     - the adoption of any plan or proposal for post-merger CoreComm's
       liquidation or dissolution proposed by or on behalf of an interested
       stockholder, or an affiliate of an interested stockholder; or

     - any reclassification of securities, recapitalization, merger with a
       subsidiary, or other transaction which has the effect, directly or
       indirectly, of increasing the proportionate share of any class of
       post-merger CoreComm's outstanding stock, or securities convertible in to
       stock, or a subsidiary owned by an interested stockholder, or an
       affiliate of an interested stockholder.

     Determinations of the fair market value of non-cash consideration are made
by a majority of the continuing directors.

     The term "continuing directors" means any member of post-merger CoreComm's
board of directors, while that person is a member of post-merger CoreComm's
board of directors, who is not a affiliate or associate or representative of the
interested stockholder and was a member of post-merger CoreComm's board of
directors prior to the time that the interested stockholder became an interested
stockholder, and any successor of a continuing director while that successor is
a member of the post-merger CoreComm's

                                       211
<PAGE>   225

board of directors, who is not an affiliate or associate or representative of
the interested stockholder and is recommended or elected to succeed the
continuing director by a majority of continuing directors.

     Voting requirements for some amendments to the charter.   The charter will
provide that the provisions set forth in this section under the heading "Special
Charter Provisions" may not be repealed or amended in any respect, unless that
action is approved by the affirmative vote of the holders of not less than
two-thirds (66 2/3%) of post-merger CoreComm's voting power. The requirement of
an increased stockholder vote is designed to prevent a stockholder who controls
a majority of post-merger CoreComm's voting power from avoiding the requirements
of the provisions discussed above by simply amending or repealing those
provisions.

THE SHAREHOLDER RIGHTS PLAN

     CoreComm currently has a shareholder rights plan in effect but concurrently
with the domestication merger, the common shares of CoreComm and the rights
attached to the shares will be exchanged for common stock of post-merger
CoreComm. The current CoreComm shareholder rights plan will therefore be
canceled by CoreComm. After the domestication merger and the ATX and Voyager
mergers are consummated, the board of directors of post-merger CoreComm may
adopt a shareholder rights plan. Any such plan would likely be substantially
identical to the one currently in place by CoreComm. Adoption of a new
shareholder rights plan by post-merger CoreComm will occur only if the
domestication merger occurs.

     The terms and provisions of the CoreComm shareholder rights plan have
various anti-takeover effects as they cause substantial dilution to a person or
group that attempts to acquire a substantial interest in CoreComm without the
prior approval of the board of directors. Among the effects of the shareholder
rights plan is that the rights from the shareholder rights plan could discourage
a takeover attempt that might otherwise allow the holders of CoreComm common
shares to sell their shares at a premium to the then current market price or
which might otherwise be beneficial to shareholders. If a similar plan is
adopted by post-merger CoreComm, these anti-takeover provisions in the
shareholder rights plan could also have a material adverse effect on the premium
that potential acquirors might be willing to pay in an acquisition or that
investors might be willing to pay in the future for shares of post-merger
CoreComm's common stock. For further discussion of the risk factors associated
with the shareholder rights plan, please refer to the section of this joint
proxy statement and prospectus entitled "Risk Factors -- Risk Factors relating
to post-merger CoreComm's capital structure -- Post-merger CoreComm will have
anti-takeover defense provisions that may deter potential acquirors and depress
its stock price."

     For more information regarding the shareholder rights plan of CoreComm,
please refer to the description of the plan in the Registration Statement on
Form 10, filed by CoreComm with the Securities and Exchange Commission on June
24, 1998 or refer to the plan itself, included as an exhibit to the Registration
Statement on Form 10-12G, filed by CoreComm with the SEC on August 19, 1998 and
Amendments Number One

                                       212

and Two to the shareholder rights plan, included as exhibits to the Form 10-K
filed by CoreComm with the SEC on March 29, 2000.

TRANSFER AGENT AND REGISTRAR

     Post-merger CoreComm's transfer agent and registrar for the common stock
will be Continental Stock Transfer & Trust Company.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

     Generally, Section 203 of the Delaware General Corporation Law prohibits a
publicly held Delaware corporation from engaging in any business combination
with an interested stockholder for a period of three years following the time
that a stockholder becomes an interested stockholder, unless:

     - prior to that time either the business combination or the transaction
       which resulted in the stockholder becoming an interested stockholder is
       approved by the board of directors of the corporation;

     - upon consummation of the transaction which resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of the voting stock of the corporation outstanding at the time
       the transaction commenced, excluding, for purposes of determining the
       number of shares outstanding, those shares held by persons who are both
       directors and officers and certain employee stock plans; or

     - at or after that time the business combination is approved by the board
       and authorized at an annual or special meeting of stockholders, and not
       by written consent, by the affirmative vote of at least two-thirds of the
       outstanding voting stock which is not owned by the interested
       stockholder.

     A business combination includes certain mergers, consolidations, asset
sales, transfers and other transactions resulting in a financial benefit to the
interested stockholder. An interested stockholder is a person who, together with
affiliates and associates, owns 15% or more of the corporation's voting stock.

INDEMNIFICATION PROVISIONS

     Section 145 of the Delaware General Corporation Law authorizes a
corporation to indemnify its directors, officers, employees and agents against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement reasonably incurred, including liabilities under the Securities Act,
provided they act in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the corporation, although in the case of
proceedings brought by or on behalf of the corporation, such indemnification is
limited to expenses and is not permitted if the individual is adjudged liable to
the corporation (unless the court determines otherwise). The registrant's
Certificate of Incorporation and Bylaws require the registrant to indemnify its
officers and directors to the full extent permitted by Delaware law.

                                       213
<PAGE>   227

     Section 102 of the Delaware General Corporation Law authorizes a
corporation to limit or eliminate its directors' liability to the corporation or
its stockholders for monetary damages for breaches of fiduciary duties, other
than for (i) breaches of the duty of loyalty, (ii) acts or omissions not in good
faith or that involve intentional misconduct or knowing violations of law, (iii)
unlawful payments of dividends, stock purchases or redemptions, or (iv)
transactions from which a director derives an improper personal benefit. The
registrant's Certificate of Incorporation contains provisions limiting the
liability of the directors to the registrant and to its stockholders to the full
extent permitted by Delaware law.

     Section 145 of the Delaware General Corporation Law authorizes a
corporation to purchase and maintain insurance on behalf of any person who is or
was a director, officer, employee or agent of the corporation against any
liability asserted against him or her and incurred by him or her in any such
capacity, or arising out of his or her status as such. The registrant's
Certificate of Incorporation and Bylaws provide that the registrant may, to the
full extent permitted by law, purchase and maintain insurance on behalf of any
director, officer, employee or agent of the registrant against any liability
that may be asserted against him or her and the registrant currently maintains
such insurance. The registrant will obtain liability insurance covering its
directors and officers for claims asserted against them or incurred by them in
such capacity, including claims brought under the Securities Act.

     Insofar as indemnification for liabilities arising from the Securities Act
may be permitted to directors, officers or persons controlling the registrant
pursuant to the foregoing provisions, the registrant has been informed that in
the opinion of the SEC, such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

CONVERTIBLE PREFERRED STOCK

     As part of the recapitalization of ATX occurring simultaneously with the
ATX merger, the ATX stockholders will create a series of convertible preferred
stock to be issued to its existing stockholders, with the material terms and
conditions as are described below.

     Dividends.   Each share of convertible preferred stock entitles its holder
to receive dividends out of funds of the corporation legally available for the
payment of dividends prior to and in preference to any declaration or payment of
any dividend on any securities junior in dividend rights to the convertible
preferred stock (other than dividends payable in the form of those junior
securities or securities convertible into those junior securities) and on a
parity with any securities that are designated to be on a parity with the
convertible preferred stock. Dividends are payable when and as authorized and
declared by the board of directors of post-merger CoreComm. Dividends on each
share of convertible preferred stock accrue at the rate determined as described
below on the liquidation value of $1,000 per share. The dividend on the
convertible preferred stock is cumulative and is payable in arrears on the
anniversary of the date of issuance of the convertible preferred stock.
Dividends accrue whether or not they have

                                       214
<PAGE>   228

been declared and whether or not there are profits, surplus or other funds of
post-merger CoreComm legally available for the payment of dividends.

     At the sole discretion of post-merger CoreComm, dividends may be paid
either in cash or in shares of common stock. If paid in shares of post-merger
CoreComm common stock, the amount of common stock to be paid will be calculated
assuming such common stock has a value equal to 98% of the volume weighted
average sale price during the prior 5 trading days immediately preceding the
dividend payment date.

     Post-merger CoreComm may not pay any dividends on any junior securities,
other than dividends payable in the form of those junior securities, unless all
accrued and unpaid dividends required to be paid on the convertible preferred
stock and any parity securities as of the immediately prior scheduled dividend
payment date have been paid in full and sufficient funds have been set aside for
the next scheduled dividend payment date. Likewise, post-merger CoreComm may not
redeem, acquire or repurchase any junior securities, except as required to
comply with an employee incentive or benefit plan, unless it is current in its
dividend payments on the convertible preferred stock and sufficient funds have
been set aside for the next scheduled dividend payment date.

     The dividend rate on the convertible preferred stock will be 3% per year
for the first 12 months after the issuance of the three-year senior notes in the
ATX merger. If any three-year senior notes remain outstanding as of the end of
that period, the rate increases to 5% per year. If any three-year senior notes
remain outstanding as of 18 months after the issuance of the three-year senior
notes in the ATX merger, the rate increases to 7% per year. The amount of
dividends payable for any period shorter or longer than a full year will be
computed daily on the basis of a 360-day year. Dividends will be payable
quarterly.

     Liquidation, Dissolution or Winding up; Mergers, Consolidations and Asset
Sales. In the event of any voluntary or involuntary liquidation, dissolution or
winding up of post-merger CoreComm, the holders of convertible preferred stock
then outstanding will be entitled to be paid out of the assets of post-merger
CoreComm available for distribution to its stockholders after payment of any
liquidation values of any securities senior in liquidation rights to the
convertible preferred stock and before any securities junior in liquidation
rights to the convertible preferred stock.

     If, upon any liquidation, dissolution or winding up of post-merger
CoreComm, the remaining assets of post-merger CoreComm available for
distribution to its stockholders are insufficient to pay the holders of
convertible preferred stock and all other classes or series of stock ranking
equal to it with respect to liquidation the full amount to which they are
entitled, the holders of convertible preferred stock and, together with holders
of the equally preferenced stock, will share ratably (based on their relative
liquidation values) in any distribution of the remaining assets and funds of
post-merger CoreComm.

     The voluntary consolidation or merger of post-merger CoreComm into another
entity, or the sale of all or substantially all of the assets of post-merger
CoreComm is not a liquidation or dissolution with respect to the convertible
preferred stock.

                                       215
<PAGE>   229

     Voting Rights.   Except as otherwise provided below or as otherwise
provided by law, holders of convertible preferred stock are not entitled to
vote.

     Post-merger CoreComm will not (a) alter, amend or repeal the preferences,
special rights or other powers or privileges of the convertible preferred stock,
or (b) create any class or series of securities senior to the convertible
preferred stock without the written consent or affirmative vote of holders of a
majority of the then outstanding shares of convertible preferred stock.

     Mandatory Redemption.   The convertible preferred stock is mandatorily
redeemable by post-merger CoreComm on the twentieth anniversary of its date of
issuance, to the extent there are funds legally available for such payment. At
such time, post-merger CoreComm will redeem all shares of the convertible
preferred stock at a redemption price of $1,000 per share, payable together with
accrued and unpaid dividends either, in the sole discretion of post-merger
CoreComm, in cash or in shares of common stock. If paid in shares of post-merger
CoreComm common stock, the amount of common stock to be paid will be calculated
assuming the common stock has a value equal to 98% of the volume weighted
average sale price during the five trading days immediately preceding the
redemption date.

     All holders of record of convertible preferred stock will be given written
notice of the redemption and the date and place for the redemption not less than
30 days nor more than 60 days prior to the redemption date. Each holder of
convertible preferred stock will surrender that holder's certificates
representing the convertible preferred stock to post-merger CoreComm at the
place designated in the notice, and on the later of the date for the redemption
and the date the certificates are surrendered, will receive the payment to which
it is entitled.

     On the redemption date, assuming notice has been provided in accordance
with the paragraph above, all rights with respect to the convertible preferred
stock, will terminate, except for the right of the holders of that stock to
receive the redemption price (in cash or common stock).

     Conversion Rights.

     Conversion at the Option of Post-merger CoreComm.   Beginning any time
after the second anniversary of the initial issuance date of the convertible
preferred stock, if the average current market price of the common stock for 20
consecutive trading days is at least 125% of the conversion price as of such
time, post-merger CoreComm can require the conversion of the convertible
preferred stock into that number of shares of common stock as is determined by
dividing the liquidation value of the shares by a number equal to the conversion
price as of that time. Similarly, at any time after the fifth anniversary, if
the current market price is equal to or greater than the conversion price at
that time, post-merger CoreComm can also require conversion of the convertible
preferred stock.

     Conversion at the Option of the Holder.   At any time, the holder of the
convertible preferred stock may convert the shares into shares of post-merger
CoreComm common stock determined by dividing the liquidation value of the shares
by a number equal to the conversion price as of such time. Furthermore, in the
event of a change of control of

                                       216
<PAGE>   230

post-merger CoreComm, the holders shall, if the then current market price is
less than the conversion price, have a one time option, upon not less than 30
days' notice nor more than 60 days' notice, to convert the convertible preferred
stock into common stock determined by dividing the liquidation price by the
greater of (a) 66.67% of the price of CoreComm common shares at the date of
issuance of the convertible preferred stock and (b) the price per common share
at which the change of control is occurring.

     Determination of the Conversion Price.   The conversion price for a
conversion made at the option of the holder in the absence of a change of
control or at the option of post-merger CoreComm is determined as follows:

- If three-year senior notes are issued to current ATX stockholders:

     The conversion price is initially $32.11 per share and is subject to upward
     adjustment, depending on the aggregate principal amount of three-year
     senior notes that remain outstanding as of the six-month anniversary of the
     completion of the ATX merger. At the six-month anniversary, if all of the
     three-year senior notes remain outstanding, the conversion price will
     remain at $32.11 per share of post-merger CoreComm common stock. If less
     than all of the three-year senior notes remain outstanding at the six-month
     anniversary, the conversion price will increase from $32.11 per share by up
     to $3.94 per share, pro rata based on the then outstanding portion of the
     maximum $110 million aggregate principal amount of three-year senior notes
     that could be issued. If no three-year senior notes are outstanding at the
     six-month anniversary, the conversion price will be $36.05 per share. The
     following chart shows, for some assumed outstanding aggregate principal
     amounts of 3-year senior notes at the six-month anniversary, the conversion
     price that would apply and the number of shares that would result from a
     full conversion of the convertible preferred stock at that conversion
     price.

</TABLE>

- If no three-year senior notes are issued to current ATX stockholders:

     The conversion price will initially be the higher of:

     (a) $40.328, subject to adjustment under the ATX merger agreement,
         multiplied by 110%; and

     (b) 100% of the volume weighted-average trading price of the CoreComm
         common shares for the 10 trading day period ending on the trading day
         prior to the closing date of the ATX merger.

     As of the date of this joint proxy statement and prospectus, the initial
     conversion price determined according to this method would be $44.36, and
     approximately 5.64

                                       217
<PAGE>   231

     million shares of post-merger CoreComm common stock would be issued upon
     conversion of all of the convertible preferred stock.

     Adjustments to Conversion Price.   The conversion price is subject to
adjustments based on changes in capitalization of post-merger CoreComm common
stock such as stock splits, stock dividends, and the like. The conversion price
will also be adjusted if, among other things, post-merger CoreComm issues to
substantially all holders of post-merger CoreComm common stock rights, options
or warrants to subscribe for or purchase shares of post-merger CoreComm common
stock at a price below the then current conversion price.

     Other Rights.   Under the terms of the registration rights agreement to be
entered into at the closing of the ATX merger, the initial holders of the
convertible preferred stock will have the right in certain circumstances to sell
their shares of convertible preferred stock or shares of common stock underlying
the convertible preferred stock in underwritten offerings. For further
information about these registration rights, please read the section of this
joint proxy statement and prospectus entitled "The Merger Agreements -- The
Merger Agreement Between CoreComm and ATX -- Related Agreements -- The
Registration Rights Agreement."

                            MORE ABOUT THE COMPANIES

                                CORECOMM LIMITED

                       UNAUDITED PRO FORMA FINANCIAL DATA

     In May 1999, CoreComm acquired MegsINet Inc. in exchange for cash and
common stock and acquired certain assets of USN Communications, Inc. in exchange
for cash and warrants to purchase common stock. The unaudited pro forma
financial data of CoreComm presented below gives effect to the completed
acquisitions of MegsINet and USN and the following proposed transactions:

     - the ATX merger only;

     - the Voyager merger only; and

     - both the ATX merger and the Voyager merger together.

     The pro forma financial data is based on CoreComm's historical financial
statements and the historical financial statements of MegsINet, USN, ATX and
Voyager. CoreComm is treated as the acquiring company for purposes of these pro
forma financial data. Certain amounts in these historical financial statements
have been reclassified to conform to CoreComm's presentation.

     CoreComm will require $40.0 million in cash for the ATX merger and
approximately $46.2 million in cash for the Voyager merger based on CoreComm's
closing stock price of $11.81 per share on August 10, 2000, as well as the
payment of any outstanding indebtedness under the Voyager credit agreement (as
of July 14, 2000, the amount was approximately $23.8 million). The unaudited pro
forma financial data has been prepared assuming Voyager does not elect to give a
termination notice based on the trading price of CoreComm's common shares.
CoreComm is evaluating its financing options and anticipates issuing additional
debt and/or equity to fund the cash portion of these mergers. We expect
post-merger CoreComm to incur negative cash flow from operations at least until
post-merger CoreComm establishes an adequate customer base for its services.
Post-merger CoreComm will require a significant amount of cash to develop its
business, fund its capital commitments and service its indebtedness and other
obligations. The unaudited pro forma financial data does not give effect to
financing required to fund future operations of the combined companies.

     The completed acquisitions have been accounted for using the purchase
method of accounting, in which the assets acquired and liabilities assumed have
been recorded at their fair values. The proposed mergers have been accounted for
using the purchase method of accounting. Accordingly, the assets acquired and
liabilities assumed have been recorded at their estimated fair values. We are
unaware of events other than those disclosed in the notes to the unaudited pro
forma financial data, including the potential adjustment to the Voyager merger
exchange ratio, that would require a material change to the preliminary purchase
price allocation. However, a final determination of necessary purchase
accounting adjustments will be made upon the completion of a study to be
undertaken to determine the fair value of certain assets and liabilities,
including

                                       219
<PAGE>   233

intangible assets. Assuming CoreComm completes the ATX merger only, the Voyager
merger only or both the ATX merger and the Voyager merger, the actual financial
position and results of operations will differ, perhaps significantly, from the
unaudited pro forma amounts reflected in this joint proxy statement and
prospectus because of a variety of factors, including access to additional
information, changes in value not currently identified and changes in operating
results between the dates of the unaudited pro forma financial data and the
dates on which the acquisitions take place.

     The unaudited pro forma condensed statements of operations for the six
months ended June 30, 2000 and the year ended December 31, 1999 give effect to
the completed acquisitions and proposed mergers as if they had been consummated
on January 1, 1999. The unaudited pro forma condensed balance sheets at June 30,
2000 give the effect to the proposed mergers as if they had been consummated on
June 30, 2000.

     ATX provided for bonuses and certain other compensation to its partners.
Upon the merger with CoreComm, the compensation of these individuals will either
cease or be reduced to be more consistent with compensation levels of other
members of management. Approximately $4.2 million and $8.5 million of expense in
the six months ended June 30, 2000 and the year ended December 31, 1999,
respectively, would not have been incurred had the merger been consummated on
January 1, 1999.

     The pro forma adjustments are based upon available information and
assumptions that we believe were reasonable at the time made. We believe that
any variations from the available information and assumptions applied will not
have a material effect on the pro forma financial data presented. The unaudited
pro forma condensed statements of operations do not purport to present
CoreComm's results of operations had the acquisitions occurred on the dates
specified, nor are they necessarily indicative of the results of operations that
may be achieved in the future. The unaudited pro forma condensed statements of
operations do not reflect any adjustments for synergies that we expect to
realize. We cannot assure you as to the amounts of, or that any, cost savings or
revenue enhancements will be realized.

     A significant component of the revenues included in the pro forma results
is the historical revenues of USN from January 1, 1999 through the date CoreComm
acquired the wireline assets of USN. Although USN quickly developed a large
customer list and revenue base in 1997 and 1998, it had difficulties under its
previous management providing services, including billing, customer care and
other operational areas, and filed for bankruptcy in February 1999. Since the
acquisition, CoreComm has been focusing on improving these operations, and has
been successful in many areas. However, CoreComm did not actively continue to
sell additional lines in these markets because it was not fully satisfied with
the quality of the operations. Consequently, and consistent with CoreComm's due
diligence, transaction structure and purchase price, revenues associated with
the USN assets have declined significantly since the acquisition, and additional
declines may continue as customers leave or "churn" off the service. However,
CoreComm anticipates that the future operating results derived from the USN
assets

                                       220
<PAGE>   234

will improve, although CoreComm has no way of assuring this. Please refer to the
section entitled "Special Note Regarding Forward-Looking Statements."

     The unaudited pro forma financial statements should be read in conjunction
with CoreComm's financial statements and related notes, and with the financial
statements and related notes of USN, MegsINet, ATX and Voyager, and the pro
forma financial statements of Voyager, incorporated by reference or appearing
elsewhere in this joint proxy statement and prospectus.

(1) The ATX share price was determined at the time of the third amendment to the
    ATX merger agreement on July 31, 2000. The Voyager merger exchange ratio is
    subject to adjustment if the average trading price prior to closing per
    common share of CoreComm is greater than $56.97 or less than $41.17. The
    ratio of cash and stock consideration that Voyager stockholders are entitled
    to receive is subject to

                                 (IN THOUSANDS)

    adjustment if less than 80% of the value of the merger consideration would
    be in the form of New CoreComm common stock based on the price prior to
    closing. The Voyager share price is based on the closing price of CoreComm
    common stock on August 10, 2000 of $11.81.

(2) The Voyager cash consideration was adjusted to represent 20% of the value of
    the merger consideration.

     The number of shares to be issued to ATX and Voyager stockholders may
change based on the share price of CoreComm's common stock. If the share price
of CoreComm's common stock were to exceed $46.38 and if the shares issued for
the ATX merger decrease by 100,000, the total price in accordance with the
purchase method of accounting would decrease by $1.4 million, which would be
allocated entirely to intangibles, and the related amount of amortization
expense would decrease by $0.3 million annually. If the average trading price
prior to closing per common share of CoreComm is less than $33.03, and if
Voyager does not elect to give a termination notice, for every $1.00 change in
the average trading price per common share of CoreComm from the $11.81 assumed
herein, the total price in accordance with the purchase method of accounting for
the Voyager merger would increase or decrease by approximately $11.5 million,
which would be allocated entirely to intangibles, and the related amount of
amortization expense would increase or decrease by approximately $2.3 million
annually.

     The intangible assets arising from the ATX merger and the Voyager merger
may include customer lists, other intangibles and goodwill. The amount of each
individual intangible is not currently determinable. The amounts of each
intangible will be determined based on appraisals and other analyses. The
amortization period for each may vary, although it is assumed in Pro Forma
Adjustment C below, that 5 years is a representative blended amortization
period.

(3) As of June 30, 2000 CoreComm would have needed to finance approximately
    $43.7 million of the cash consideration and repayment of the Voyager bank
    loan assuming the completion of both mergers. The cash consideration for the
    Voyager merger is subject to adjustment. The assumed interest rate used for
    the pro forma data is 12.0%. As of June 30, 2000, CoreComm did not need any
    additional financing to complete the ATX merger or the Voyager merger.

        outstanding phantom units under its

(1) The ATX share price was determined at the time of the third amendment to the
    ATX merger agreement on July 31, 2000. The Voyager merger exchange ratio is
    subject to adjustment if the average trading price prior to closing per
    common share of CoreComm is greater than $56.97 or less than $41.17. The
    ratio of cash and stock consideration that Voyager stockholders are entitled
    to receive is subject to adjustment if less than 80% of the value of the
    merger consideration would be in the form of New CoreComm common stock based
    on the price prior to closing. The Voyager share price is based on the
    closing price of CoreComm common stock on August 10, 2000 of $11.81.

(2) The Voyager cash consideration was adjusted to represent 20% of the value of
    the merger consideration.

     The number of shares to be issued to ATX and Voyager stockholders may
change based on the share price of CoreComm's common stock. If the share price
of CoreComm's common stock were to exceed $46.38 and if the shares issued for
the ATX merger decrease by 100,000, the total price in accordance with the
purchase method of accounting would decrease by $1.4 million, which would be
allocated entirely to intangibles, and the related amount of amortization
expense would decrease by $.03 million annually. If the average trading price
prior to closing per common share of CoreComm is less than $33.03, and if
Voyager does not elect to give the termination notice, for every $1.00 change in
the average trading price per common share of CoreComm from the $11.81 assumed
herein, the total price in accordance with the purchase method of accounting for
the Voyager merger would increase or decrease by approximately $11.5 million,
which would be allocated entirely to intangibles, and the related amount of
amortization expense would increase or decrease by approximately $2.3 million
annually.

     The intangible assets arising from the ATX merger and the Voyager merger
may include customer lists, other intangibles and goodwill. The amount of each
individual intangible is not currently determinable. The amounts of each
intangible will be determined based on appraisals and other analyses. The
amortization period for each may vary, although it is

     These acquisitions were accounted for using the purchase method of
accounting. Accordingly, the purchase prices were allocated to assets acquired
and liabilities assumed based upon their estimated fair values at the dates of
acquisitions.

     Condensed pro forma financial statements are presented for the companies
listed above with the following exceptions. The pro forma combined historical
results for Starnet, Inc., American Information Services, Inc., and Internet
Connection Services, LLC were not deemed to be material and are not included for
the year ended December 31, 1999. The unaudited pro forma condensed consolidated
statement of operations for the year ended December 31, 1999 assumes, that for
the acquired entities presented, that the acquisitions in 1999 and 2000 had
occurred on January 1, 1999. The unaudited pro forma condensed consolidated
statement of operations for the six months ended June 30, 2000 assumes, that for
the acquired entities presented, that the acquisition in 2000 had occurred on
January 1, 2000. The unaudited pro forma condensed consolidated statements of
operations are not necessarily indicative of the results of operations that
would actually have occurred if the transactions had been consummated as of
January 1, 1999 and January 1, 2000 and are not intended to indicate the
expected results for any future period. These statements should be read in
conjunction with the historical consolidated financial statements and related
notes of Voyager.net, and certain acquired businesses, included herein.

     had occurred on that date.

B.   Voyager.net utilized $4.4 million of its revolving credit facility to
     complete the acquisitions in 2000. Additional interest expense on the
     related debt would have been approximately $0.5 million. The assumed
     interest rate was 8.5% for all periods presented.

                        FINANCIAL STATEMENTS (UNAUDITED)

A.   Acquired customer bases in the amount of $58.4 million are being amortized
     over a three-year period beginning January 1, 1999 as if the acquisitions
     had occurred on that date.

B.   The expense related to the issuance of common stock and options has been
     excluded from the pro forma condensed consolidated statement of operations
     since it is a non-recurring charge.

C.   Voyager.net utilized $51.2 million of its revolving credit facility to
     complete the acquisitions in 1999 and in 2000. Additional interest expense
     on the related debt would have been approximately $2.7 million. The assumed
     interest rate was 8.5% for all periods presented.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
             VOYAGER FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RECENT ACCOUNTING INTERPRETATION

     On December 3, 1999, the SEC issued Staff Accounting Bulletin 101, Revenue
Recognition in Financial Statements. SAB 101 summarizes some of the SEC's
interpretations of the application of generally accepted accounting principles
to revenue recognition. Revenue recognition under SAB 101 was initially
effective for the Company's first quarter 2000 financial statements. However,
SAB 101B, which was released June 26, 2000, delayed adoption of SAB 101 until no
later than the fourth fiscal quarter 2000. Changes resulting from SAB 101
require that a cumulative effect of such changes for 1999 and prior years be
recorded as an adjustment to net income on January 1, 2000 plus adjust the
statement of operations for the three months ended in the quarter of adoption.

     Although Voyager is still in the process of reviewing SAB 101, it believes
that its revenue recognition practices are in substantial compliance with SAB
101 for the year ending December 31, 2000 or that adoption of its provisions
would not be material to its annual or quarterly results of operations.

ACQUISITIONS

     Voyager's acquisition strategy was designed to leverage its existing
network and administrative operations to allow it to enter new markets within
the Midwest, as well as to expand its presence in existing markets, and to
realize economies of scale. Since December 31, 1999 Voyager has acquired two
Internet service provider businesses in the Midwest totaling approximately
12,200 subscribers. Below is a summary of Voyager's completed acquisitions, with
the number of subscribers acquired at the respective date of acquisition:

   Three Months Ended June 30, 2000 Compared to June 30, 1999

     Revenues.   Total consolidated revenues increased from $10.7 million for
the three months ended June 30, 1999 to $18.6 million for the three months ended
June 30, 2000, representing an increase of 74%. The revenue growth was primarily
driven by the increase in Voyager's customer base from approximately 222,000 at
June 30, 1999 to approximately 368,000 at June 30, 2000. The growth in customers
was the result of both organic growth and acquisition activity; Voyager
experienced internal growth from its effort to provide high quality customer and
technical service and support, geographic expansion in its coverage areas and
low customer churn rates.

     Internet access service costs.   Internet access service costs increased
from $3.6 million for the three months ended June 30, 1999 to $7.4 million for
the three months ended June 30, 2000. Internet access service costs as a percent
of revenue increased from 34% for the three months ended June 30, 1999 to 40%
for the three months ended June 30, 2000 due to investments in our network
infrastructure and call centers. The increase in spending was primarily a result
of an increase in customers and their associated network expenses and an
increase in billing costs.

                                       246
<PAGE>   260

     Sales and marketing.   Sales and marketing expenses increased from $1.2
million for the three months ended June 30, 1999 to $2.2 million for the three
months ended June 30, 2000. The increase in spending was primarily attributable
to the growth in Voyager's customer base and support functions and the expansion
of its geographic coverage area. As a percent of revenue, sales and marketing
costs remained relatively constant at approximately 11% to 12% for the three
months ended June 30, 1999 and 2000.

     General and administrative.   General and administrative expenses increased
from $3.0 million for the three months ended June 30, 1999 to $5.9 million for
the three months ended June 30, 2000. The absolute increase in spending was due
to the growth of Voyager's business and the administrative functions necessary
to support Voyager's growth. As a percentage of revenue, general and
administrative costs increased from 28% for the three months ended June 30, 1999
to 32% for the three months ended June 30, 2000 due to additional recurring
expenses as a result of Voyager's initial public offering on July 21, 1999.
These recurring expenses included public relations, investor relations, and
increases in legal, audit, and insurance. Additional expenses are a result of
additional staff requirements as a result of Voyager's growth from June 30, 1999
to June 30, 2000.

     Depreciation and amortization.   Depreciation and amortization expenses
increased from $5.0 million for the three months ended June 30, 1999 to $10.2
million for the three months ended June 30, 2000. This increase was primarily a
result of the amortization of intangible assets related to acquiring Voyager's
customer base since June 30, 1998, as well as increased capital spending for
expanded network operations and infrastructure.

     Compensation charge for issuance of common stock and stock
options.   Voyager incurred a charge of $1.0 million for the three months ended
June 30, 1999 and $25,000 for the three months ended June 30, 2000 related to
the issuance of common stock and stock options. The amount of this charge was
based on the issuance and grant of common stock and options at purchase and
exercise prices below fair market value and a charge to reflect vesting of
previously issued common stock or options granted. Voyager believes these
charges to be non-recurring in nature because it expects to issue all future
shares and stock options at prices that approximate market value. However, some
unvested options to purchase common stock will continue to vest over the next
four years, which will result in additional compensation expense of
approximately $76,000 in periods subsequent to June 30, 2000.

     Other expenses, net.   Other expenses, net decreased from $1.0 million for
the three months ended June 30, 1999 to $0.7 million for the three months ended
June 30, 2000. This decrease is the net result of interest income on notes
receivable from related parties offset by a higher average balance on Voyager's
line-of-credit which was used to fund acquisitions completed during 1999 and
2000.

     Net loss.   As a result of the above, Voyager reported net loss of $4.5
million, or $0.19 per share applicable to common stockholders, for the three
months ended June 30, 1999 as compared to net loss of $7.9 million, or $0.25 per
share applicable to common stockholders, for the three months ended June 30,
2000.

     EBITDA.   EBITDA increased from $2.8 million for the three months ended
June 30, 1999 to $3.1 million for the three months ended June 30, 2000. EBITDA
represents earnings before interest, taxes, depreciation, amortization and
non-recurring, non-cash compensation charges. EBITDA is provided because it is a
measure commonly used by investors to analyze and compare companies on the basis
of operating performance. EBITDA is not a measurement of financial performance
under generally accepted accounting principles and should not be construed as a
substitute for operating income, net income or cash flows from operating
activities for purposes of analyzing our operating performance, financial
position and cash flows. EBITDA, as calculated by Voyager, is not necessarily
comparable with similarly titled measures for other companies.

   Six Months Ended June 30, 2000 Compared to June 30, 1999

     Revenues.   Total consolidated revenues increased from $19.2 million for
the six months ended June 30, 1999 to $36.7 million for the six months ended
June 30, 2000, representing an increase of 91%. The revenue growth was primarily
driven by the increase in Voyager's customer base from approximately 222,000 at
June 30, 1999 to approximately 368,000 at June 30, 2000. The growth in customers
was the result of both organic growth and acquisition activity. Voyager
experienced internal growth from its effort to provide high quality customer and
technical service and support, geographic expansion in its coverage areas and
low customer churn rates.

     Internet access service costs.   Internet access service costs increased
from $6.4 million for the six months ended June 30, 1999 to $14.6 million for
the three months ended June 30, 2000. Internet access service costs as a percent
of revenue increased from 33% for the six months ended June 30, 1999 to 40% for
the six months ended June 30, 2000 due to investments in Voyager's network
infrastructure and call centers. The increase in spending period over period was
primarily a result of an increase in customers and their associated network
expenses and an increase in billing costs.

     Sales and marketing.   Sales and marketing expenses increased from $2.2
million for the six months ended June 30, 1999 to $4.4 million for the six
months ended June 30, 2000. The increase in spending was primarily attributable
to the growth in Voyager's customer base and support functions and the expansion
of its geographic coverage area. As a percent of revenue, sales and marketing
costs remained relatively constant at approximately 11% to 12% for the six
months ended June 30, 1999 and 2000.

     General and administrative.   General and administrative expenses increased
from $5.5 million for the six months ended June 30, 1999 to $11.9 million for
the six months ended June 30, 2000. The absolute increase in spending was due to
the growth of Voyager's business and the administrative functions necessary to
support its growth. As a percentage of revenue, general and administrative costs
increased from 29% for the six months ended June 30, 1999 to 32% for the six
months ended June 30, 2000 due to additional recurring expenses as a result of
Voyager's initial public offering on July 21, 1999. These recurring expenses
included public relations, investor relations, and increases in legal, audit,
and insurance. Additional expenses are a result of additional staff

                                       248
<PAGE>   262

requirements as a result of Voyager's growth from June 30, 1999 to June 30,
2000. Headcount for General and Administrative staffing increased 41% from June
30, 1999 to June 30, 2000.

     Depreciation and amortization.   Depreciation and amortization expenses
increased from $8.5 million for the six months ended June 30, 1999 to $18.4
million for the six months ended June 30, 2000. This increase was primarily a
result of the amortization of intangible assets related to acquiring Voyager's
customer base since June 30, 1998, as well as increased capital spending for
expanded network operations and infrastructure.

     Compensation charge for issuance of common stock and stock
options.   Voyager incurred a charge of $2.5 million for the six months ended
June 30, 1999 and $50,000 for the six months ended June 30, 2000 related to the
issuance of common stock and stock options. The amount of this charge was based
on the issuance and grant of common stock and options at purchase and exercise
prices below fair market value and a charge to reflect vesting of previously
issued common stock or options granted. Voyager believes these charges to be
non-recurring in nature because it expects to issue all future shares and stock
options at prices that approximate market value. However, some unvested options
to purchase common stock will continue to vest over the next four years, which
will result in additional compensation expense of approximately $76,000 in
periods subsequent to June 30, 2000.

     Other expenses, net.   Other expenses, net decreased from $1.8 million for
the six months ended June 30, 1999 to $1.2 for the six months ended June 30,
2000. This decrease is the net result of interest income on notes receivable
from related parties offset by a higher average balance on Voyager's
line-of-credit which was used to fund acquisitions completed during 1998, 1999
and 2000.

     Net loss.   As a result of the above, Voyager reported net loss of $7.8
million, or $0.35 per share applicable to common stockholders, for the six
months ended June 30, 1999 as compared to net loss of $13.8 million, or $0.44
per share applicable to common stockholders, for the six months ended June 30,
2000.

     EBITDA.   EBITDA increased from $5.1 million for the six months ended June
30, 1999 to $5.8 million for the six months ended June 30, 2000. EBITDA
represents earnings before interest, taxes, depreciation, amortization and
non-recurring, non-cash compensation charges. EBITDA is provided because it is a
measure commonly used by investors to analyze and compare companies on the basis
of operating performance. EBITDA is not a measurement of financial performance
under generally accepted accounting principles and should not be construed as a
substitute for operating income, net income or cash flows from operating
activities for purposes of analyzing our operating performance, financial
position and cash flows. EBITDA, as calculated by Voyager, is not necessarily
comparable with similarly titled measures for other companies.

  Fiscal Year Ended December 31, 1999 Compared to Fiscal Year Ended December 31,
  1998

     Revenues.   Total consolidated revenues increased from $10.7 million for
the twelve months ended December 31, 1998 to $48.5 million for the twelve months
ended December 31, 1999, representing an increase of 353.2%. The revenue growth
was driven by the increase in Voyager's customer base from approximately 142,000
at December 31, 1998 to approximately 336,000 at December 31, 1999. The growth
in customers was primarily the result of Voyager's acquisition activity and
strong internal growth from Voyager's effort to provide high quality customer
and technical service and support, geographic expansion in Voyager's coverage
areas and low customer churn rates.

     Internet Access Service Costs.   Internet access service costs increased
from $3.6 million for the twelve months ended December 31, 1998 to $15.9 million
for the twelve months ended December 31, 1999. The increase in absolute spending
for the twelve months ended December 31, 1999 was primarily the result of an
increase in customers and their associated network expenses and an increase in
billing expenses for the increased customer base. Internet access service costs
as a percent of revenue decreased from 33.7% for the twelve months ended
December 31, 1998 to 32.9% for the twelve months ended December 31, 1999 due to
improved telecommunication contracts and economies of scale, partially offset by
higher telecommunication costs being incurred by the entities acquired during
September and October.

     Sales and Marketing.   Sales and marketing expenses increased from $2.0
million for the twelve months ended December 31, 1998 to $6.4 million for the
twelve months ended December 31, 1999. The increase in spending was attributable
to the growth in Voyager's customer base and support functions and the expansion
of its geographic coverage area. As a percentage of revenue, sales and marketing
expenses decreased from 18.5% for the twelve months ended December 31, 1998 to
13.2% for the twelve months ended December 31, 1999. The decrease in sales and
marketing expenses as a percentage of revenue reflects lower average customer
acquisition costs, which is primarily attributable to the strong word of mouth
and referral programs offered by Voyager.net.

     General and Administrative.   General and administrative expenses increased
from $3.4 million for the twelve months ended December 31, 1998 to $14.2 million
for the twelve months ended December 31, 1999. The absolute increase in spending
was primarily due to the growth of Voyager's business and the administrative
functions necessary to support Voyager's growth. As a percentage of revenue,
general and administrative costs decreased from 31.8% for the twelve months
ended December 31, 1998 to 29.2% for the twelve months ended December 31, 1999.
The decrease on a percentage basis represents leveraging of resources across an
increased customer base.

     Depreciation and Amortization.   Depreciation and amortization expense
increased from $3.9 million for the twelve months ended December 31, 1998 to
$23.8 million for the twelve months ended December 31, 1999. This increase was
primarily the result of the amortization of intangible assets related to
acquiring Voyager's customer base since December 31, 1998, as well as increased
capital spending for expanded network operations and infrastructure.

     Compensation Charge for Issuance of Common Stock and Stock
Options.   Voyager incurred a charge of $4.2 million for the twelve months ended
December 31, 1998 which decreased to $2.6 million for the twelve months ended
December 31, 1999. These charges were based on the issuance and grant of common
stock and options to purchase at exercise prices below fair market value and a
charge to reflect vesting of previously issued common stock or options granted.
Voyager believes these charges to be non-recurring in nature because Voyager
expects to issue all future shares and stock options at prices that approximate
market value. However, some unvested options to purchase common stock will
continue to vest over the next three years, which will result in additional
compensation expense of approximately $111,000 in periods subsequent to December
31, 1999.

     Other Income (Expense), Net.   Other expense, net increased from $0.9
million for the twelve months ended December 31, 1998 to $1.7 million for the
twelve months ended December 31, 1999. This increase is the result of the higher
average balance during the first seven months of 1999 on Voyager's
line-of-credit which was used to fund acquisitions completed during 1998 and
1999. The line of credit was paid off on July 25, 1999 with proceeds from the
initial public offering.

     Net Loss.   As a result of the above, Voyager reported net loss of $(7.3)
million, or $(0.43) per share applicable to common stockholders, for the twelve
months ended December 31, 1998 as compared to net loss of $(16.1) million, or
$(0.61) per share applicable to common stockholders, for the twelve months ended
December 31, 1999.

     EBITDA (as defined).   EBITDA increased from $1.7 million for the twelve
months ended December 31, 1998 to $12.0 million for the twelve months ended
December 31, 1999. As a percentage of revenues, EBITDA increased from 16.1% for
the twelve months ended December 31, 1998 to 24.8% for the twelve months ended
December 31, 1999.

  Fiscal Year Ended December 31, 1998 Compared to Fiscal Year Ended December 31,
  1997

     Revenues.   Total consolidated revenues increased from $3.5 million for the
year ended December 31, 1997 to $10.7 million for the year ended December 31,
1998, representing an increase of 205.7%. The revenue growth was primarily
driven by the increase in Voyager's customer base from approximately 17,000 at
December 31, 1997 to approximately 142,000 at December 31, 1998. The growth in
customers was primarily a result of the seven acquisitions during 1998, which
added approximately 100,000 subscribers to our customer base.

     Internet Access Service Costs.   Internet access service costs increased
from $1.3 million for the year ended December 31, 1997 to $3.6 million for the
year ended December 31, 1998. Internet access service costs as a percent of
revenue decreased from 37.1% for the year ended December 31, 1997 to 33.6% for
the year ended December 31, 1998 due to improved telecommunication contracts and
economies of scale. The increase in absolute spending for the year ended
December 31, 1998 was driven by a significant

                                       251
<PAGE>   265

increase in customers and their associated network expenses and an increase in
billing costs.

     Sales and Marketing.   Sales and marketing expense increased from $1.0
million for the year ended December 31, 1997 to $2.0 million for the year ended
December 31, 1998. The increase in absolute spending was a result of the rapid
growth of Voyager's operations and the acquisitions completed during 1998. As a
percentage of revenue, sales and marketing costs decreased from 28.6% for the
year ended December 31, 1997 to 18.7% for the year ended December 31, 1998. The
decrease of sales and marketing expenses as a percentage of revenues reflects
the efficiencies of Voyager's marketing programs over a larger customer base.

     General and Administrative.   General and administrative expenses increased
from $1.5 million for the year ended December 31, 1997 to $3.4 million for the
year ended December 31, 1998. The absolute increase in spending was due to the
increase in support functions and basic infrastructure necessary to support the
expansion of Voyager's business and the acquisition activity. As a percentage of
revenue, general and administrative expenses decreased from 42.9% for the year
ended December 31, 1997 to 31.8% for the year ended December 31, 1998. The
decrease on a percentage basis represents efficiencies achieved through the
integration of acquired businesses and leveraging resources across an increased
customer base.

     Depreciation and Amortization.   Depreciation and amortization expense
increased from $394,000 for the year ended December 31, 1997 to $3.9 million for
the year ended December 31, 1998. This increase was a result of the amortization
of intangible assets related to acquiring Voyager's customer base since December
31, 1997, as well as increased capital spending for expanded network operations
and infrastructure.

     Compensation Charge for Issuance of Common Stock and Stock
Options.   Voyager incurred a charge of $4.2 million for the year ended December
31, 1998 related to the issuance of common stock and stock options. The amount
of this charge was based on the issuance and grant of common stock and options
at purchase and exercise prices below fair market value.

     Other Income (Expense), Net.   Other expenses, net increased from $62,000
for the year ended December 31, 1997 to $0.9 million for the year ended December
31, 1998. This increase is the result of the higher average balance on Voyager's
$40.0 million line-of-credit which was used to fund acquisitions completed
during 1998.

     Net (Loss).   As a result of the above, Voyager reported a net loss of
$(0.8) million, or $(0.10) per share, applicable to common stockholders, for the
year ended December 31, 1997 as compared to a net loss of $(7.3) million, or
$(0.43) per share applicable to common stockholders, for the year ended December
31, 1998.

     EBITDA.   EBITDA increased from ($364,000) for the year ended December 31,
1997 to $1.7 million for the year ended December 31, 1998. As a percentage of
revenues, EBITDA increased from (10.5%) for the year ended December 31, 1997 to
16.1% for the year ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES.

     Voyager's principal capital and liquidity needs historically have related
to funding the cash portion of acquisitions, sales and marketing activities, the
development and expansion of network infrastructure, the establishment of
customer service and support operations and general working capital needs.
Voyager's capital needs have historically been met through receipts from its
prepaid customer base and additional capital from outside sources, including
vendor capital leases, and the use of a $60.0 million revolving credit facility
with a bank group led by Fleet National Bank.

     On July 21, 1999, Voyager completed its initial public offering in which it
raised net proceeds of approximately $99.5 million. Upon closing of the
offering, $60.6 million of senior bank debt and accrued interest and fees were
repaid, $8.8 million of preferred stock and cumulative dividends were redeemed,
and $2.3 million of subordinated notes and accrued interest were repaid. Since
the initial public offering, Voyager has used all of the remaining proceeds for
general corporate purposes, acquisitions and capital expenditures.

     Net cash provided by operating activities was $1.7 million for the six
months ended June 30, 2000, compared to net cash provided by operating
activities of $4.6 million for the six months ended June 30, 1999. The primary
sources of cash from operating activities for the six months ended June 30, 2000
were $18.0 million in depreciation and amortization. These sources were
partially offset by a $13.8 million net loss and a $1.1 million increase in
deferred revenue.

     Net cash used in investing activities was $10.1 million for the six months
ended June 30, 2000, compared to net cash used in investing activities of $26.2
million for the six months ended June 30, 1999. Net cash provided from investing
activities for the six months ended June 30, 2000 consisted of $5.3 million to
acquire two Internet service provider businesses and $4.8 million for the
purchase of capital equipment. Cash used in investing activities for the six
months ended June 30, 1999 related to acquisition activity and the purchase of
capital equipment.

     Net cash provided by financing activities was $2.7 million for the six
months ended June 30, 2000, compared to net cash provided by financing
activities of $24.0 million for the six months ended June 30, 1999. The primary
sources of cash from financing activities for the six months ended June 30, 2000
was the use of proceeds from Voyager's revolving credit facility and payments on
capital leases.

     Voyager believes that available cash on hand, amounts available under the
credit facility, additional capital financing arrangements and cash flow from
operations will be sufficient to meet Voyager's capital requirements for the
next twelve months. Voyager's capital requirements depend on numerous factors
including market acceptance of its services, its ability to maintain and expand
its customer base, the rate of expansion of its infrastructure, the roll out of
its DSL plan, which is expected to be available in selected Midwest cities at
the end of the third quarter 2000 and other factors.

YEAR 2000 COMPLIANCE.

     Voyager relies on third party telecommunications and information systems
equipment and software that may not be Year 2000 compliant to provide its
services. Voyager's efforts to address Year 2000 issues prior to January 1,
2000, included conducting an audit of its own systems and of its third-party
suppliers as to assessment. Voyager developed and implemented a remediation plan
with respect to third-party software, computer technology and services that may
have failed to be Year 2000 compliant. Costs incurred to date related to Year
2000 issues have not been material, nor does it expect to incur additional
material costs related to Year 2000 issues.

FORWARD-LOOKING STATEMENTS


     This Management's Discussion and Analysis of Financial Condition and
Results of Operations contains "forward-looking statements" within the meaning
of Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934 that are subject to future events, risk and uncertainties
that could cause actual results to differ materially from those expressed or
implied. These statements can sometimes be identified by use of forward-looking
words such as "may," "will," "anticipate," "estimate," "expect," or "intend."
Important factors that either individually or in the aggregate could cause
actual results to differ materially from those expressed include, without
limitation, (1) the risk that the merger of Voyager and CoreComm will not be
consummated, (2) Voyager's ability to provide superior customer care, (3) the
success of its growth strategy, (4) its ability to integrate acquisitions
successfully, (5) increased competition from regional and national Internet
service providers, (6) Voyager's ability to rollout its DSL strategy and (7)
general economic conditions.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Voyager believes its exposure to market rate fluctuations on its
investments is nominal due to the short-term nature of these investments.
Voyager has no material future earnings or cash flow exposures with respect to
its capital leases, which are all at fixed rates. To the extent it has
borrowings outstanding under its credit facility, Voyager would have market risk
relating to those amounts because the interest rates under the credit facility
are variable. At present, Voyager has no plans to enter into any hedging
arrangements with respect to those borrowings.

                                      ATX

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
               ATX FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion and analysis should be read in conjunction with
the unaudited condensed financial statements and notes thereto of ATX included
herein as well as the combined financial statements and notes included in this
joint proxy statement and prospectus. This information is not necessarily
indicative of future operating results. Except for the historical information
contained below, the matters discussed in this section are forward-looking
statements that involve a number of risks and uncertainties, including those
described in "Risk Factors." ATX's actual liquidity needs, capital resources and
operating results may differ materially from the discussion set forth below in
these forward-looking statements.

GENERAL

     ATX operates a switch and facilities-based network that provides integrated
voice and broadband data services including long distance, local and network
services, Internet access and Web consulting, development and hosting. ATX was
formed in 1985 and began as a switch and facilities-based provider of long
distance services. Over time, ATX expanded its product offerings to meet the
needs of its customers.

     ATX has diversified its revenues by broadening its services in becoming a
competitive local exchange carrier, Internet service provider and offering web
based hosting and networking services to new and existing customers. ATX is in
the process of transitioning local customers to its switched-based facility
which ATX believes will increase gross profit margins by significantly reducing
local carrier costs.

     Until it was organized on February 9, 2000 as a corporation, ATX conducted
its business operations through two limited partnerships, ATX Telecommunications
Services, Ltd. and Global Telecom Services, Ltd. Upon the incorporation of ATX,
Inc., ATX was subject to federal and state income taxation. ATX did not provide
for an income tax benefit for the six months ended June 30, 2000 based on the
uncertainty of future earnings and profits.

   Year Ended December 31, 1999 as Compared to Year Ended December 31, 1998

      Revenues

     Revenues increased by $21.4 million to $135.0 million in fiscal year 1999
from $113.7 million in fiscal year 1998, representing an 18.8% increase. The
increase was primarily due to the increase in long distance traffic and the
development of local, Internet and network integration service revenues. There
was also an increase in long distance traffic. The components of revenues
include the diversification of services related to local exchange service,
network and Internet and wireless based revenues. Local exchange revenues
increased $14.4 million, representing an increase of 215.3% from fiscal year
1998. Network and wireless services revenues increased $4.7 million,
representing an increase of 33.3% from fiscal 1998. Long distance revenues
increased $2.3 million, representing an increase of 2.5% from fiscal year 1998.

      Gross Profit

     Gross profit increased to $49.5 million in fiscal year 1999 from $45.2 in
fiscal year 1998, representing an increase of 9.5%. Gross profit as a percentage
of revenues decreased 3.1% in fiscal year 1999 from 39.8% to 36.7% in fiscal
year 1998, primarily as a result of ATX's lower gross margin for providing local
exchange service in a resale environment.

      Selling, General and Administrative Expenses

     Selling, general and administrative expenses increased to $51.2 million in
fiscal year 1999 from $43.3 million in fiscal year 1998 but decreased as a
percentage of revenues to 37.9% in fiscal year 1999 from 38.1% in fiscal year
1998. Selling, general and administrative expenses, excluding partners' salaries
and bonuses, increased $7.9 million relating to the expansion of the sales force
and infrastructure in anticipation of providing additional local exchange
service and other products. Salaries and related expenses excluding partners'
salaries and bonuses are the most significant component of selling, general and
administrative expenses and decreased as a percentage of selling, general and
administrative expenses to 46.9% in fiscal year 1999 from 50.4% in fiscal year
1998. Selling, general and administrative expenses, excluding partners' salaries
and bonuses, represented 31.0% and 29.9% of revenues for fiscal year 1999 and
fiscal year 1998, respectively.

      Net Loss

     As a result of the expansion of the sales force and customer service in
anticipation of future local exchange service and new product growth and Year
2000 expenditures, ATX incurred a net loss of $1.6 million in fiscal year 1999
compared with net income of $2.1 million in fiscal year 1998.

   Year Ended December 31, 1998 as Compared to Year Ended December 31, 1997

      Revenues

     Revenues increased $21.1 million to $113.7 million in fiscal year 1998 from
$92.6 million in fiscal year 1997, representing an increase of 22.8%. The
increase was primarily due to the development of new products, including local
exchange service and Internet based revenues. Local exchange service, network
and Internet and wireless based revenues increased $11.5 million, representing a
123.6% increase from fiscal year 1997. Long distance revenues increased $9.6
million, representing a 11.5% increase from fiscal year 1997.

      Gross Profit

     Gross profit increased to $45.2 million in 1998 from $39.8 in 1997,
representing an increase of 13.6%. Gross profit as a percentage of revenues
decreased 3.2% to 39.8% in 1998 from 43.0% in 1997 primarily as a result of
local carrier costs that resulted in lower margins in 1998 compared with 1997.

      Selling, General and Administrative Expenses

     Selling, general and administrative expenses increased to $43.3 million in
fiscal year 1998 from $26.4 million in fiscal year 1997 and increased as a
percentage of revenues to 38.1% in fiscal year 1998 from 28.5% in fiscal year
1997. Salaries and related expenses, excluding partners' salaries and bonuses,
are the most significant component of selling, general and administrative
expenses and decreased to 50.4% of selling, general and administrative expenses
in fiscal year 1998 from 51.4% in fiscal year 1997. In fiscal year 1998,
selling, general and administrative expenses included partners bonuses of $8.0
million compared to $0 in fiscal year 1997. Selling, general and administrative
expenses,

                                       259
<PAGE>   273

excluding partners' bonuses and salaries, increased $8.9 million relating to the
expansion of the sales force and infrastructure in anticipation of providing
local exchange service and other products. Selling, general and administrative
expenses, excluding partners' bonuses and salaries, represented 29.9% and 27.1%
of revenues for fiscal year 1999 and fiscal year 1998, respectively.
Additionally, ATX instituted a phantom unit plan for its employees in fiscal
year 1998 that resulted in a non-cash charge to selling, general and
administrative expenses of $1.8 million in fiscal year 1998.

      Net Income

     As a result of the partners' bonuses of $8 million and increased cost of
revenues due to expansion of the sales force and costs related to increased
customer service in anticipation of future local exchange service growth, ATX's
net income decreased to $2.1 million in fiscal year 1998 compared to net income
of $13.6 million in fiscal year 1997.

LIQUIDITY AND CAPITAL RESOURCES

     ATX intends to continue its growth and its coverage of products and
services in the northeastern region of the United States. ATX plans to expand
its local exchange services through the build out of co-locations and purchases
of network equipment. ATX has historically funded expansion into new markets,
offering of new products and services and capital acquisitions through
operations. If the ATX merger is not consummated, ATX may seek to raise
additional funds through short term borrowings or private investment or raise
capital in the public markets to fund those estimated capital expenditures and
expansion of Competitive Local Exchange Service including the build out of
co-locations and customer transition costs from a resale environment to its
network. There can be no assurance that such funding will be available on
acceptable terms and conditions which may cause the delay of certain of ATX's
development plans.

     ATX believes that its future cash flows from operations will be sufficient
to fund its growth and future capital expenditures for the next 12 months
including the additional costs relating to the expansion of Completive Local
Exchange Service and its effect on future operations and earnings. ATX's
expectations of future capital requirements and cash flows are based on current
estimates and such estimates include the future increase in overall operating
gross margins upon transitioning local exchange customers to its network. Based
on the terms and conditions of the ATX merger agreement, ATX cannot be sure that
actual costs or the timing and scope of the expenditures will be consistent with
current estimates.

     Cash and cash equivalents increased $300,000 at June 30, 2000 to $3.5
million from $3.2 million as of December 31, 1999. The increase is primarily
attributable to cash provided by operation activities of $4.7 million, advances
from related parties and capital contributions of $1.9 million, net of capital
expenditures of $6.3 million.

INFLATION

     ATX management does not believe that its business is impacted by inflation
to a significantly different extent than the general economy.

     ATX is not currently subject to the reporting requirements of the
Securities Exchange Act of 1934, and accordingly does not file any reports,
proxy statements or other information with the SEC. Upon the filing of the
registration statement on Form S-4 and the completion of the ATX merger and the
Voyager merger, however, post-merger CoreComm will become subject to the
Exchange Act and will be required to file the applicable reports, proxy
statements and other information with the SEC. You will be able to obtain copies
of these filed documents from post-merger CoreComm, and you will be able to
review and copy these documents in the manner described above.

     This joint proxy statement and prospectus will be part of a registration
statement on Form S-4 to be filed with the SEC under the Securities Act of 1933
by the surviving company in the ATX merger, which will be named CoreComm
Limited, to register the issuance of its common stock to the current
shareholders of CoreComm and the current stockholders of Voyager. Those shares
will be held by public stockholders only if the ATX merger is approved and
completed. This joint proxy statement and prospectus will also be part of a
registration statement on Form S-4 to be filed with the SEC under the Securities
Act by the Delaware corporation into which CoreComm will merge in the
domestication merger, to register the issuance of its common stock to the
current shareholders of CoreComm and the current stockholders of Voyager in
connection with the Voyager merger. Those shares will be held by public
stockholders only if the Voyager merger is approved and completed but the ATX
merger is not.

     This joint proxy statement and prospectus, which will constitute a part of
each registration statement, does not contain all the information that will be
set forth in the

                                       262
<PAGE>   276

registration statements. Some items of information will be contained in exhibits
to the registration statements, as permitted by the rules and regulations of the
SEC. Statements made in this joint proxy statement and prospectus as to the
content of any contract, agreement or other document referred to are not
necessarily complete. With respect to each of those contracts, agreements or
other documents to be filed or incorporated by reference as an exhibit to the
relevant registration statement, you should refer to the corresponding exhibit,
when it is filed, for a more complete description of the matter involved and
read all statements in this joint proxy statement and prospectus in light of
that exhibit.

     Because the completion of each of the Voyager merger and the ATX merger is
not conditioned on the completion of the other, until the required shareholder
votes occur and the mergers that are approved are completed, it is not possible
to know which company will survive the mergers as the ultimate parent company.
Therefore, registration statements for the surviving company resulting from
completion of the ATX merger and the surviving company resulting from the
completion of only the Voyager merger and not the ATX merger will be filed.
However, the stock of only one company -- the ultimate parent company, depending
on which mergers occur -- will be held and publicly traded.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a discussion of the material United States federal income
tax consequences of the Voyager merger, the ATX merger and the domestication
merger. The following discussion and the United States federal income tax
opinions referred to below are based on and subject to the Internal Revenue Code
of 1986, as amended, the regulations promulgated thereunder, existing
administrative interpretations and court decisions and related laws, all of
which are subject to change, possibly with retroactive effect, and based on
assumptions, limitations, representations and covenants, including those
contained in the representation letters of CoreComm, ATX and Voyager referred to
below. This discussion does not address all aspects of United States federal
income taxation that may be important to you in light of your particular
circumstances or if you are subject to special rules, such as rules relating to:

     - shareholders who are not citizens or residents of the United States

     - financial institutions

     - tax-exempt organizations

     - insurance companies

     - dealers in securities

     - shareholders who acquired their shares of CoreComm or Voyager common
       stock through the exercise of options or similar derivative securities or
       otherwise as compensation

     - shareholders who hold their shares of CoreComm or Voyager common stock as
       part of a straddle or conversion transaction.

     This discussion assumes that you hold your CoreComm common stock or Voyager
common stock as a capital asset within the meaning of Section 1221 of the
Internal Revenue Code.

     None of CoreComm, ATX or Voyager has requested or intends to request a
ruling from the Internal Revenue Service regarding the tax consequences of any
of the transactions with respect to CoreComm, ATX, Voyager or the shareholders
of CoreComm, ATX or Voyager. Accordingly, no assurance can be given that the
statements set forth in this discussion, which do not bind the Internal Revenue
Service or the courts, will not be challenged by the Internal Revenue Service or
sustained by the courts if so challenged.


     Paul, Weiss, Rifkind, Wharton & Garrison, counsel to CoreComm, has
delivered an opinion that the description of the federal income tax consequences
to holders of CoreComm common shares contained under the heading "Treatment of
CoreComm Shareholders" below and under the heading "Reporting Requirements"
below correctly sets forth the material federal income tax consequences for
CoreComm shareholders. Goodwin, Procter & Hoar LLP, counsel to Voyager, has
delivered an opinion that the description of the federal income tax consequences
to holders of Voyager Common Stock contained under the heading "Treatment of
Voyager Stockholders" below and under the


                                       264
<PAGE>   278

heading "Reporting Requirements" below correctly sets the forth material federal
income tax consequences for Voyager shareholders. Those opinions and the
opinions set forth in the following paragraph are based on, among other things,
representation letters provided to counsel by CoreComm, ATX and Voyager that
will be confirmed by CoreComm, ATX and Voyager prior to the closing of the
respective mergers.

     Based upon, among other things, the representation letters referred to in
the preceding paragraph, (a) it is the opinion of Paul, Weiss, Rifkind, Wharton
& Garrison that the domestication merger constitutes for federal income tax
purposes a reorganization described in Section 368(a) of the Internal Revenue
Code; (b) it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison that the
ATX merger constitutes for federal income tax purposes a reorganization
described in Section 368(a) of the Internal Revenue Code and/or an exchange
described in Section 351 of the Internal Revenue Code; (c) it is the opinion of
Paul, Weiss, Rifkind, Wharton & Garrison that the Voyager merger constitutes for
federal income tax purposes a reorganization within the meaning of Section
368(a) of the Internal Revenue Code and/or an exchange described in Section 351
of the Internal Revenue Code and (d) it is the opinion of Goodwin, Procter &
Hoar LLP that the Voyager merger constitutes for federal income tax purposes a
reorganization described in Section 368(a) of the Internal Revenue Code and/or
an exchange described in Section 351 of the Internal Revenue Code. It is a
condition to the obligation of CoreComm to complete the ATX merger that CoreComm
shall have received the written opinion of its counsel to the effect set forth
in clause (b) of the preceding sentence, and that such opinion shall not have
been withdrawn. It is a condition to the respective obligations of CoreComm and
Voyager to complete the Voyager merger that each shall have received the written
opinion of its respective counsel to the effect set forth in clauses (c) and (d)
of the preceding sentence, and that such opinion shall not have been withdrawn.

TREATMENT OF CORECOMM SHAREHOLDERS

   Consequences of the Domestication Merger to CoreComm Shareholders.

     A holder of CoreComm common shares who, under the domestication merger,
exchanges CoreComm common shares for common stock of the newly-formed wholly-
owned subsidiary of CoreComm will not recognize gain or loss as a result of this
exchange, provided that CoreComm does not have any earnings and profits at the
time of the domestication merger and further provided that, in the case of
holders of CoreComm common shares that own less than 10% of CoreComm, such
holder files an election with the Internal Revenue Service to include earnings
and profits in lieu of recognizing gain. CoreComm believes it will not have any
earnings and profits at the time of the domestication merger. The tax basis of
the common shares received by the holder will be equal to the tax basis of the
common shares surrendered, and the holding period of the common shares will
include the holding period of the CoreComm common shares surrendered.

                                       265
<PAGE>   279

  Consequences of the ATX Merger, If the Voyager Merger Does Not Occur, and
  Consequences of the ATX Merger and the Voyager Merger, If Both Occur, to
  CoreComm Shareholders Who Have Become Stockholders of the Newly-Formed
  Wholly-Owned Subsidiary of CoreComm Under the Domestication Merger

     If the ATX merger occurs and the Voyager merger does not occur or if both
the ATX merger and the Voyager merger occur, a holder of common stock received
under the domestication merger who exchanges such common stock for ATX common
stock under the ATX merger will not recognize gain or loss as a result of such
exchange. The tax basis of the post-merger CoreComm common stock received by the
holder will be equal to the tax basis of the domesticated CoreComm Merger Sub,
Inc. common stock surrendered, and the holding period of the post-merger
CoreComm common stock will include the holding period of the common stock of
CoreComm Merger Sub, Inc. surrendered.

  Consequences of the Voyager Merger, If the ATX Merger Does Not Occur, to
  CoreComm Shareholders Who Have Become Stockholders of the Newly-Formed
  Wholly-Owned Subsidiary of CoreComm Under the Domestication Merger

     If the Voyager merger occurs and the ATX merger does not occur, a holder of
domesticated CoreComm Merger Sub, Inc. common stock received under the
domestication merger will not recognize gain or loss as a result of the Voyager
merger.

TREATMENT OF VOYAGER STOCKHOLDERS

     A holder of Voyager stock will recognize gain as a result of the Voyager
merger equal to the lesser of the amount of cash received or the amount of gain
realized. The holder's tax basis in the common stock of post-merger CoreComm
received in the Voyager merger will be the holder's tax basis in the Voyager
stock surrendered, decreased by the amount of cash received and increased by the
amount of gain recognized, and the holder's holding period in the common stock
of CoreComm (or its successor) received in the Voyager merger will include the
holding period in the Voyager stock surrendered.

TAX IMPLICATIONS TO CORECOMM, ATX AND VOYAGER

     CoreComm, ATX and Voyager will not recognize gain or loss for United States
federal income tax purposes as a result of the domestication merger, the ATX
merger and/or the Voyager merger.

REPORTING REQUIREMENTS

     If you participate in an exchange of stock under the domestication merger,
the ATX merger and/or the Voyager merger, you will be required to retain records
and attach a statement to your tax returns for the taxable year in which the
mergers are completed that contains facts relating to the exchange of stock,
including the cost or other basis of stock surrendered in the merger(s) and the
amount of stock received under the merger(s). All stockholders are urged to
consult their own tax advisors to determine the

                                       266
<PAGE>   280

specific information that they may need to retain and/or file with the Internal
Revenue Service.

     This foregoing discussion is not intended to be a complete analysis or
description of all potential United States federal income tax consequences or
any other consequences of the merger(s). In addition, this discussion does not
address tax consequences that may vary with, or are contingent on, your
individual circumstances. Moreover, this discussion does not address any
non-income tax or any foreign, state or local tax consequences of the merger(s).
Accordingly, you are strongly urged to consult with your tax advisor to
determine the particular United States federal, state, local or foreign income
or other tax consequences to you of the mergers.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1.   BASIS OF PRESENTATION:

     These condensed consolidated financial statements of Voyager.net, Inc. and
its subsidiaries (the "Company") for the three and six months ended June 30,
2000 and 1999 and the related footnote information are unaudited and have been
prepared by the Company pursuant to the rules and regulations of the Securities
and Exchange Commission. These financial statements included herein should be
read in conjunction with the Company's audited consolidated financial statements
and the related notes to the consolidated financial statements as of and for the
year ended December 31, 1999, which are included in the Company's Form 10-K
filed with the Securities and Exchange Commission and dated March 31, 2000. In
management's opinion, the accompanying unaudited financial statements contain
all adjustments (consisting of normal, recurring adjustments) which management
considers necessary to present the consolidated financial position of the
Company at June 30, 2000 and the results of its operations and cash flows for
the three and six months ended June 30, 2000 and 1999. Certain information and
footnote disclosures normally included in the financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations. The results of operations for
the three and six months ended June 30, 2000 are not necessarily indicative of
the results of operations expected for the year ended December 31, 2000.

2.   BUSINESS COMBINATIONS:

     During the six months ended June 30, 2000, the Company acquired certain
assets used in connection with the Internet access service business of two
entities as described below:

     February 11, 2000, the Company purchased assets of Valley Business
Equipment, Inc. for approximately $4,050,000. Approximately $3,910,000 was
allocated to the acquired customer base cost as a result of this transaction.

     March 12, 2000, the Company purchased assets of Livingston On-Line for
approximately $325,000. Approximately $310,000 was allocated to the acquired
customer base cost as a result of this transaction.

     The unaudited pro forma combined historical results, as if the entities
listed above had been acquired at the beginning of the six months ended June 30,
2000 and 1999, respectively, and if all entities acquired in 1999 had been
acquired at the beginning of 1999 are included in the table below.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The pro forma results above include amortization of intangibles and
interest expense on debt assumed issued to finance the acquisitions. The pro
forma results are not necessarily indicative of what actually would have
occurred if the acquisitions had been completed as of the beginning of each of
the fiscal periods presented, nor are they necessarily indicative of future
consolidated results.

3.   DEBT:

     The Company has a revolving available credit facility with a bank group in
the amount of $60 million, with the option to extend to $70 million, on similar
terms and conditions. The credit facility matures on June 30, 2005. The
revolving credit facility agreement allows the Company to elect an interest rate
as of any borrowing date based on either the (1) prime rate, or (2) LIBOR, plus
a margin ranging from 0.5% to 2.75% depending on the ratio of funded debt to
EBITDA. The elected rate as of June 30, 2000 is approximately 8.70%. Automatic
and permanent reductions of the maximum commitments begin June 30, 2001 and
continue until maturity.

4.   EARNINGS PER SHARE:

     The impact of dilutive shares is not significant. Net loss per share is
computed using the weighted average number of common shares outstanding during
the period. Inclusion of common share equivalents of 3,983,847 would be
antidilutive and have been excluded from per share calculations.

5.   SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION:

     The following is the supplemental cash flow information for all periods
presented:

</TABLE>

6.   STOCK-BASED COMPENSATION PLAN:

     During the six months ended June 30, 2000, the Company granted 545,381
options to purchase common stock to certain members of management, employees and

employees. At the grant date, all of the options granted vest in four equal
annual installments beginning January 6, 2001. The exercise price for these
options was not less than the fair market value of the Company's common stock on
the grant date. Therefore, no additional compensation expense has been
recognized in the six months ended June 30, 2000 for these options.

     During the six months ended June 30, 2000, the Company recognized
compensation expense of $50,000 relating to options granted prior to January 1,
2000.

7.   RECENT ACCOUNTING INTERPRETATION:

     On December 3, 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin 101 ("SAB 101"), Revenue Recognition in Financial
Statements. SAB 101 summarizes some of the SEC's interpretations of the
application of generally accepted accounting principles to revenue recognition.
Revenue recognition under SAB 101 was initially effective for the Company's
first quarter 2000 financial statements. However, SAB 101B, which was released
June 26, 2000, delayed adoption of SAB 101 until no later than the fourth fiscal
quarter 2000. Changes resulting from SAB 101 require that a cumulative effect of
such changes for 1999 and prior years be recorded as an adjustment to net income
on January 1, 2000 plus adjust the statement of operations for the three months
ended in the quarter of adoption.

     Although the Company is still in the process of reviewing SAB 101, it
believes that its revenue recognition practices are in substantial compliance
with SAB 101 for the year ending December 31, 2000 or that adoption of its
provisions would not be material to its annual or quarterly results of
operations.

8.   MERGER AGREEMENT:


     On March 12, 2000, the Company entered into an agreement to merge with
CoreComm Limited in a stock and cash transaction. The transaction is subject to
stockholder approval, certain regulatory approvals and other conditions.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and the Stockholders of
Voyager.net, Inc.:

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, stockholders' equity (deficit)
and cash flows, present fairly, in all material respects, the financial position
of Voyager.net, Inc. and its subsidiaries (the "Company") at December 31, 1999
and 1998, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   Organization and basis of presentation

     Voyager.net, Inc. (the "Company ") owns 100% of Voyager Information
Networks, Inc., which was incorporated in the State of Michigan in 1994.
Voyager.net was incorporated in 1998 in the State of Delaware under the name
Voyager Holdings, Inc. The Company's name was changed to Voyager.net, Inc. on
April 29, 1999. The Company provides full service access to the Internet for
corporate and residential users in Michigan, Illinois, Indiana, Minnesota, Ohio
and Wisconsin.

   Revenue recognition

     The Company recognizes revenue for dial-up Internet access services,
dedicated Internet access services and value-added Web services when the
services are provided. Dial-up and dedicated Internet access service plans range
from one month to one year. Value-added Web services are sold on a monthly
basis. Advance collections relating to future access services are recorded as
deferred revenue and recognized as revenue when earned.

   Cash equivalents

     The Company considers all highly liquid investments purchased with an
initial maturity of three months or less to be cash equivalents.

   Property and equipment

     Property and equipment are stated at cost and depreciated over their
estimated useful lives using the straight-line method. Equipment acquired under
capital leases is depreciated over the related lease terms or the estimated
productive useful lives, depending on the criteria met in determining the
qualification as a capital lease. Costs of repair and maintenance are charged to
expense as incurred.

   Intangible assets

     Intangible assets consist primarily of the cost of the acquired customer
base. The acquired customer base is amortized using the straight-line method
over 3 years based on the estimated customer churn rate. Bank financing fees,
included in intangible assets, are being amortized on a straight-line basis over
the term of the related debt. Other intangible assets are amortized over a 10
year period. Impairments, if any, are measured based upon discounted cash flow
analyses and are recognized in operating results in the period in which the
impairment in value is determined.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

   Advertising costs

     Advertising costs are expensed as incurred. Advertising expense of
approximately $372,000, $185,000 and $1,174,000 was charged to operations in
1997, 1998 and 1999, respectively.

   Financial instruments

     The Company's financial instruments, as defined by Statement of Financial
Accounting Standards ("SFAS") No. 107 "Disclosures About Fair Value of Financial
Instruments," consist of cash, notes payable and long-term debt. The Company's
estimate of the fair value of these financial instruments approximates their
carrying amounts at December 31, 1998 and 1999.

   Use of estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   Income taxes

     A current tax liability or asset is recognized for the estimated taxes
payable or refundable on tax returns for the year. Deferred tax liabilities or
assets are recognized for the estimated future tax effects of temporary
differences between financial and tax accounting.

     The aforementioned acquisitions were accounted for using the purchase
method of accounting. The operations of the entities are included in the income
statement of Voyager.net from the acquisition date forward. For each
acquisition, the excess of cost of the acquired assets less liabilities assumed
resulted in a substantial portion of the purchase price being allocated to the
acquired customer base (see Note 4).

acquisition and the preceding year, as if the entities listed above had been

8. DEBT

     In July 1999, the Company re-negotiated its revolving available credit
facility with its bank group concurrent with its initial public offering (see
Note 11) for a $60 million line of credit, with the option to extend to $70
million on similar terms and conditions. The credit facility matures on
September 30, 2005. At December 31, 1999, $19,650,000 was outstanding under the
credit facility. Interest is payable quarterly through maturity. The revolving
credit facility agreement allows the Company to elect an interest rate as of any
borrowing date based on either the (1) prime rate, or (2) LIBOR, plus a margin
ranging from 1.0% to 2.75% depending on the ratio of funded debt to EBITDA. The
elected rate as of December 31, 1999 is approximately 9.0% with an effective
weighted average rate of approximately 8.6% and 8.4% at December 31, 1998 and
1999, respectively. Commitment fees on the unused credit facility are 0.5%.
Automatic and permanent reductions of the maximum commitments begin April 2001
and continue until maturity. Based on the balance as of December 31, 1999, the
scheduled permanent reductions of long-term debt are as follows:

12. STOCK-BASED COMPENSATION PLAN

     In 1998, a Stock Option and Incentive Plan (the "Plan") was established.
The Plan provides for the ability to issue Stock Options (either Incentive Stock
Options or Non-Qualified Stock Options), Stock Appreciation Rights, Restricted
Stock Awards, Deferred Stock Awards, Unrestricted Stock Awards, Performance
Share Awards and Dividend Equivalent Rights. As of December 31, 1999, there were
4,816,160 options to purchase common stock authorized with 1,626,658 options
available for issuance.

     The Plan provides for the granting of options to officers, employees,
consultants, members of the Board of Directors and other key persons for
purchase of the Company's common shares. The Plan is administered by the Board
of Directors. No option can be for a term of more than ten years from the grant
date. The option price and the vesting provisions are determined by the Board of
Directors at the time of the grant.

     Stock option activity under the Plan during the year ended December 31,
1998 and 1999 (there were no stock options granted during 1997) are as follows:

10 years. During 1998, the Company issued 2,232,000 shares of restricted common
stock to certain members of management for a nominal amount; 496,000 of which
were subject to certain vesting provisions at December 31, 1998 through October
2002. During 1999, the Company issued an aggregate of 1,240,000 shares of
restricted common stock at $4.84 per share to a member of management and the
Chairman of the Board. Certain of these shares were subject to vesting through
2003. Prior to the Company's initial public offering, all shares of the unvested
restricted common stock were accelerated and became 100% fully vested. The
weighted average fair value at issuance for the restricted common stock and
options were $1.77 and $6.16 per share at December 31, 1998 and 1999,
respectively. Accordingly, the Company recorded compensation expense of
$4,218,407 and $2,563,311 for the years ended December 31, 1998 and 1999,
respectively.

     Under SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS 123),
compensation cost is measured at the grant date based on the value of the award
and is recognized over the service (or vesting) period. Under SFAS 123, the
Company's net loss and loss per share for the years ended December 31, 1998 and
1999 would have been adjusted to the pro forma amounts indicated in the
following table:

     On April 9, 2000, ATX, Inc. and its stockholders ("ATX Stockholders")
entered into a plan of recapitalization and merger ("Merger Agreement") with
CoreComm Limited ("CoreComm"). Under the terms of the merger agreement, as
amended, the ATX stockholders will exchange their issued and outstanding common
stock for the following aggregate consideration: (i) approximately 12.4 million
shares of CoreComm common stock; (ii) $250 million of CoreComm's 3% senior
convertible preferred stock and (iii) $150 million in cash from CoreComm. Such
amounts may be subject to adjustments as defined in the merger agreement. In the
event CoreComm has not completed a debt or equity financing prior to the closing
date, CoreComm may elect to issue short term notes of $110 million and reduce
the cash consideration by such amount. The Merger Agreement is subject to
regulatory and CoreComm shareholder approval, amongst other conditions.

3.   BASIS OF PRESENTATION

     In the opinion of management, all adjustments which have been made are
necessary to present fairly the financial position of the Company as of June 30,
2000 and 1999 and the results of operations for the six month periods ended June
30, 2000 and 1999. The

             NOTES TO UNAUDITED FINANCIAL STATEMENTS -- (CONTINUED)

results of operations for the six month period ending June 30, 2000 are not
necessarily indicative of the results to be experienced for the fiscal year
ending December 31, 2000.

     The Statements and related notes herein have been prepared pursuant to the
rules and regulations of the Securities and Exchange Commission. Accordingly,
certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been omitted pursuant to such rules and regulations. The accompanying notes
should therefore be read in conjunction with the Company's December 31, 1999
financial statements included elsewhere herein.

INCOME TAXES

     Upon the incorporation of ATX, Inc as of February 9, 2000, ATX is subject
to federal and state income taxation. ATX did not provide for an income tax
benefit for the Six Months ended June 30, 2000 based on the uncertainty of
future earnings and profits.

     Prior to the incorporation of ATX, Inc., the partners were required to
report their respective share of the Company's profits and losses in their
individual income tax returns. Accordingly, no provision for federal, state and
local income taxes is reflected in these statements for periods prior to
February 9, 2000.

4.   PHANTOM UNIT PLAN

     The Phantom Unit Plan ("the Plan") provides for the issuance of a total of
5,000,000 phantom units. The phantom units shall become payable on the earlier
of termination or a change of control. Upon the termination of employment, such
phantom unit holders shall be entitled to compensation. Such compensation shall
be payable over a 36-month period beginning in the thirteenth month after
termination. Compensation is determined by the Phantom Unit Plan's formula and
is based on average net income as defined in the Plan for the three years prior
to termination.

     Upon a change in control as defined in the Plan, the Company will record a
compensation charge equal to the fair market value of the phantom units. Such
event would be the consummation of the Merger Agreement above resulting in a
charge of approximately 5% of the fair market value of the aggregate
consideration as described in Note 2.

5.   SUPPLEMENTAL CASH FLOW INFORMATION

     Prior to the merger into ATX, Inc. distributions were made to the former
partners of ATX of approximately $4.3 million to satisfy their loan balances.
Additionally, loans to an officer of the Company were forgiven of approximately
$1.9 million and shown as a contribution to equity.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

ATX Telecommunications Services Group
Bala Cynwyd, Pennsylvania

     We have audited the accompanying combined balance sheets of ATX
Telecommunications Services Group as of December 31, 1999, 1998 and 1997, and
the related combined statements of operations, changes in partners' capital, and
cash flows for the years then ended. These financial statements are the
responsibility of the management of ATX Telecommunications Services Group. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of ATX
Telecommunications Services Group as of December 31, 1999, 1998 and 1997, and
the results of their operations and their cash flows for the three years then
ended in conformity with generally accepted accounting principles.

distance, local, data, private line, cellular, PC-based billing, prepaid
calling, paging, Internet access and World Wide Web consulting, development and
hosting.

     These partnerships were terminated on February 9, 2000 upon their merger
into ATX Telecommunication Services, Inc. ("ATX, Inc."). ATX, Inc. was
incorporated on the above date in the state of Delaware upon the consent of the
Company's partners. ATX, Inc. was capitalized with 10,000 shares of common stock
at $.01 par value. Upon the merger, 1,000 shares of common stock was issued to
the former partners of ATX and Global. On such date, the Company contributed its
assets and its liabilities were assumed by ATX, Inc. at their historical cost
basis.

     The partnership agreement provides for the allocation of profits and losses
on an annual basis. Profits and losses are allocated among partners based on the
partnership agreement.

     Distributions, other than liquidating distributions, shall be made to all
partners in proportion to their percentage interests except as otherwise
stipulated in the partnership agreement.

     The partnership agreement required that during 1999 certain partners
receive distributions totaling $1,350,000 for prior years. This agreement also
provides for bonuses to these partners totaling $8,000,000 per year for the
years 1998 through 2002. The Company has recorded compensation expenses for
these bonuses included in selling, general and administrative expenses for the
years ended December 31, 1999 and 1998, respectively.

     If a sale or public offering of the Company does not occur before January
31, 2003, certain minority partners have an option to put their respective
interests to the Company at fair value, as defined within the partnership
agreement. The total amount to be paid to these partners for their respective
interests will be paid over a seven and one-half year period.

2. PLAN OF RECAPITALIZATION AND MERGER

     On March 9, 2000, ATX, Inc. and its stockholders ("ATX Stockholders")
entered into a plan of recapitalization and merger ("Merger Agreement") with
CoreComm Limited ("CoreComm"). Under the terms of the merger agreement, ATX will

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

recapitalized such that the ATX Stockholders will receive the following
aggregate consideration: (i) approximately 12.4 million shares of CoreComm
common stock; (ii) $250 million of CoreComm's 3% senior preferred stock and
(iii) $150 million in cash from CoreComm. Such amounts may be subject to
adjustments as defined in the merger agreement. In the event CoreComm has not
completed a debt or equity financing prior to the closing date, CoreComm may
elect to issue short term notes of $70 million and reduce the cash consideration
by such amount. The Merger Agreement is subject to regulatory and CoreComm
shareholder approval, among other conditions.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   Revenue Recognition

     The Company recognizes revenue based on the customers' usage of services.
Revenues are presented net of estimated discounts. Additionally, the Company
accrues for unbilled telecommunication revenue as a result of its billing cycle
and such amounts are included in accounts receivable.

   Cost of Revenues

     Cost of revenues includes network costs which consist of access, transport,
and termination costs. Such costs are recognized when incurred in connection
with the provision of telecommunication services.

   Cash Equivalents

     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

   Property and Equipment

     Property and equipment are stated at cost. Depreciation and amortization
are provided by the straight-line method over the estimated useful lives of the
respective assets. Property and equipment are depreciated over useful lives
ranging from five to seven years and leasehold improvements are amortized over
the terms of the lease.

   Intangible Assets

     Intangible assets represent acquired customer lists which are being
amortized using the straight line method over a 7-year period. Intangible assets
are presented net of accumulated amortization of $522,504, $343,933 and $165,362
as of December 31, 1999, 1998 and 1997, respectively.

                     ATX TELECOMMUNICATIONS SERVICES GROUP

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

   Impairment of Assets

     The Company's long-lived assets and identifiable intangibles are reviewed
for impairment whenever events or changes in circumstances indicate that the net
carrying amount may not be recoverable. When such events occur, the Company
measures impairment by comparing the carrying value of the long-lived asset to
the estimated undiscounted future cash flows expected to result from the use of
the assets and their eventual disposition. The Company determined that, as of
December 31, 1999, there had been no impairment in the carrying value of the
long-lived and intangible assets.

   Advertising and Marketing Costs

     All costs related to advertising and marketing the Company's products and
services are expensed in the period incurred.

   Income Taxes

     The partners are required to report their respective share of the Company's
profits and losses in their individual income tax returns. Accordingly, no
provision for federal, state and local income taxes is reflected in the
financial statements.

   Concentrations of Credit Risk

     The Company maintains its cash deposits and temporary cash investments with
high-quality institutions at levels which may exceed federally insured limits.
The Company has not experienced any losses on cash deposits or temporary cash
investments maintained in this manner.

     The Company sells its telecommunications services and products to customers
operating primarily in the Northeastern region of the United States. The Company
performs ongoing credit evaluation of its customers, and it generally does not
require collateral from those customers.

   Fair Value of Financial Instruments

     The carrying value of all financial instruments approximates their fair
value due to the short maturity of the respective instruments.

   Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

7. RELATED PARTY TRANSACTIONS

     There are various transactions with a partner of the Company relating to
certain professional services approximating $1,000,000 for each of the years
1999, 1998 and 1997. These transactions resulted in intercompany balances shown
as payables to related parties, with the related costs reflected in general and
administrative expenses. Additionally, companies affiliated with this partner
advanced funds to the Company for their operations and purchases of certain
telecommunication equipment. These amounts have no formal repayment terms or
interest rates and are shown as payables, related party.

     Additionally, the Company advanced funds to certain partners. These amounts
are included in receivables, partners and had no formal repayment terms or
interest rates. Subsequent to December 31, 1999, prior to the partnerships'
merger into ATX, Inc., a distribution of approximately $4.3 million was declared
and satisfied by the above mentioned receivables, partners.

10. RETIREMENT PLAN

     The Company's employees participate in a defined contribution profit
sharing plan established under Section 401(k) of the Internal Revenue Code. The
plan allows employees to defer up to 15% of their income through contributions
to the plan on a pretax basis, subject to a statutory dollar limitation. In
accordance with the provisions of the plan, the employer may match employees'
contributions. In addition, the employer may make optional contributions to the
plan. The Company and other business entities controlled by a partner of the
Company participate in this plan. The Company made matching contributions to the
plan for the years ended December 31, 1999, 1998 and 1997 of $176,166, $127,670
and $58,047, respectively.

11. PHANTOM UNIT PLAN

     During 1998, ATX adopted the 1998 Phantom Unit Plan (the "Plan"). The Plan
provides for the issuance of a total of 5,000,000 phantom units representing a
phantom 5% equity interest in ATX. Eligible employees may receive phantom units
or equivalent consideration as determined by a committee appointed by ATX to
administer the Plan. The committee has the authority at its sole discretion to
designate the employees eligible to participate in the Plan. In addition, the
committee may terminate or amend the Plan at its discretion. Termination or
amendment of the Plan shall not affect phantom awards previously granted.
Typically, the awards vest over a seven-year period from the date of grant;
however, an employee may receive credit for employment time prior to the date of
the award at the discretion of the committee. The Plan is unfunded.

     The phantom units become payable to a participant on the earlier of his
termination of employment or a change of control. Upon termination of
employment, a participant is entitled to compensation under the Plan. Such
compensation is payable over a 36-month period beginning in the thirteenth month
after termination. The participant's compensation is determined by his
proportionate ownership of units and the Plan's formula for determining value,
which is 10 times average net cash income as defined in the Plan for the prior
three fiscal years.

     The Company has recorded a noncash (benefit) charge of ($400,000) and
$1,800,000 for the years ended December 31, 1999 and 1998, respectively, related
to the issuance of the phantom units.

     Upon a change in control as defined in the Plan, the participants will
become entitled to receive compensation based upon the exchange or transaction
value of ATX's equity. ATX, Inc. will record a compensation charge equal to the
fair market value of the consideration payable to the Plan participants less
amounts previously recorded. The consummation of the Merger Agreement, described
in Note 2 above, would result in a non-cash charge of approximately $44 million.

                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of March 12, 2000,
by and among CoreComm Limited, a Bermuda corporation ("Parent"), CoreComm Group
Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of Parent
("MergerCo"), and Voyager.net, Inc., a Delaware corporation (the "Company").

                                    RECITALS

     WHEREAS, the respective Boards of Directors of Parent, MergerCo and the
Company have approved the merger of MergerCo with and into the Company (the
"Merger") in accordance with the Delaware General Corporation Law (the "DGCL")
and, upon the terms and subject to the conditions set forth in this Agreement,
holders of shares of common stock, par value $.0001 per share, of the Company
(the "Company Common Stock") issued and outstanding immediately prior to the
Effective Time (as hereinafter defined) will be entitled, subject to the terms
and conditions hereof, to the right to receive shares of common stock, par value
$.01 per share, of Parent (the "Parent Common Stock") and cash, without any
interest thereon, subject to certain adjustments;

     WHEREAS, the Board of Directors of the Company (the "Company Board") has,
in light of and subject to the terms and conditions set forth herein, (i)
determined that (A) the consideration to be paid for each share of Company
Common Stock in the Merger is fair to the stockholders of the Company, and (B)
the Merger is in the best interests of the Company and its stockholders, and
(ii) resolved to approve and adopt this Agreement and the transactions
contemplated or required by this Agreement, including the Merger (collectively,
the "Transactions"), and to recommend approval and adoption by the stockholders
of the Company of this Agreement and the Transactions;

     WHEREAS, as a condition to the willingness of Parent and MergerCo to enter
into this Agreement, Media/Communications Partners II Limited Partnership,
Media/ Communications Investors Limited Partnership Glenn R. Friedly and
Christopher P. Torto and certain of their affiliates (collectively, the
"Principal Stockholders") have entered into a Voting Agreement, dated as of the
date hereof, with Parent and MergerCo (the "Voting Agreement"), pursuant to

Principal Stockholder's shares of Company Common Stock in favor of the approval
of the Transactions, upon the terms and subject to the conditions set forth in
the Voting Agreement;

Internal Revenue Code of 1986, as amended (the "Code") and to cause the Merger
to qualify as a reorganization under the provisions of Section 368(a) of the
Code or (ii) agree to a transaction that qualifies as an exchange under the
provisions of Section 351 of the Code; and

                                       A-6
<PAGE>   336

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, Parent, MergerCo and the Company hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1 The Merger.   Subject to the terms and conditions of this Agreement, at
the Effective Time, the Company and MergerCo shall consummate the Merger
pursuant to which (a) MergerCo shall be merged with and into the Company and the
separate corporate existence of MergerCo shall thereupon cease, (b) the Company
shall be the successor or surviving corporation in the Merger (sometimes
hereinafter referred to as the "Surviving Corporation") and shall continue to be
governed by the laws of the State of Delaware and the DGCL, and (c) the separate
corporate existence of the Company with all its rights, privileges, immunities,
powers and franchises shall continue unaffected by the Merger. Without limiting
the generality of the foregoing, and subject thereto, at the Effective Time, all
the properties, rights, privileges, powers and franchises of the Company and
MergerCo shall vest in the Surviving Corporation, and all debts, liabilities and
duties of the Company and MergerCo shall become the debts, liabilities and
duties of the Surviving Corporation. The Company shall take such steps as are
permitted under the DGCL to (i) amend the Certificate of Incorporation of the
Company (the "Company Certificate") so that the Certificate of Incorporation of
MergerCo, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation, and (ii) amend
the Bylaws of the Company (the "Company Bylaws") so that the Bylaws of MergerCo,
as in effect immediately prior to the Effective Time, shall be the Bylaws of the
Surviving Corporation until thereafter amended as provided by law, by the
Certificate of Incorporation of the Surviving Corporation and by such Bylaws.
Notwithstanding the foregoing, the name of the Surviving Corporation shall be
"CoreComm-Voyager, Inc." and the Certificate of Incorporation and Bylaws of the
Surviving Corporation shall so provide. The Merger shall have the effects
specified in the DGCL, including Section 259 of the DGCL.

     1.2 Effective Time.   As promptly as practicable after all of the
conditions set forth in Article IX shall have been satisfied or, if permissible,
waived by the party entitled to the benefit of the same, MergerCo and the
Company shall duly execute and file a certificate of merger (the "Certificate of
Merger") with the Secretary of State of the State of Delaware in accordance with
the DGCL. The Merger shall become effective as of the time of the Certificate of
Merger has been duly filed or such other subsequent date or time as shall be

     agreed upon by the parties and set forth in the Certificate of Merger and
in accordance with the DGCL (the "Effective Time").

     1.3 Closing.   The closing of the Merger (the "Closing") shall take place
at such time and on a date to be specified by the parties, which shall be no
later than the second business day after satisfaction or waiver of all of the
conditions set forth in Article IX

                                       A-7
<PAGE>   337

hereof (the "Closing Date"), at the offices of Paul, Weiss, Rifkind, Wharton &
Garrison, 1285 Avenue of the Americas, New York, NY 10019, unless another date
or place is agreed to by the parties hereto.

     1.4 Tax Consequences.   It is intended by all of the parties hereto that
the Merger will qualify both or either (i) as a reorganization within the
meaning of Section 368(a) of the Code or (ii) a transaction that, together with
the Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration. All of the
parties to this Agreement agree to report the Merger, for all purposes, in a
manner which is consistent with the preceding sentence and no party shall take
any action, or fail to take any action which action or failure to take such
action would cause the Merger to fail to qualify (i) as a reorganization within
the meaning of Section 368(a) of the Code or (ii) a transaction that, together
with the Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration. However, it is
further intended by all of the parties hereto that if the transactions with ATX
Communications Services, Inc. ("ATX") described in Section 8.11 occur, and this
Agreement is assigned as provided in Section 11.5, then the incorporation of
ATX, the transactions with ATX described in Section 8.11, and the transactions
described in this Agreement will be treated for U.S. federal income tax purposes
as one integrated transaction qualifying as an exchange under the provisions of
Section 351 of the Code in which the shareholders of the Company transfer
Company Common Stock in exchange for ATX stock.

                                   ARTICLE II

                             DIRECTORS AND OFFICERS
                          OF THE SURVIVING CORPORATION

     2.1 Directors of the Surviving Corporation.   The directors of MergerCo
immediately prior to the Effective Time shall be the directors of the Surviving
Corporation immediately after the Effective Time until their successors shall
have been duly elected or appointed and qualified or until their earlier death,
resignation or removal in accordance with the Certificate of Incorporation and
Bylaws of the Surviving Corporation. The Company will use reasonable efforts to
cause any director who is a designee of the Company on the Board of Directors of
any Company Subsidiary to resign as of the Effective Time.

     2.2 Officers of the Surviving Corporation.   The officers of the Company
immediately prior to the Effective Time shall be the officers of the Surviving
Corporation immediately after the Effective Time until their successors shall
have been duly elected or appointed and qualified or until their earlier death,
resignation or removal in accordance with the Certificate of Incorporation and
Bylaws of the Surviving Corporation.

                                  ARTICLE III

                   EFFECT OF THE MERGER ON THE CAPITAL STOCK
                        OF THE CONSTITUENT CORPORATIONS

     3.1 Effect on Capital Stock.   As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of Company
Common Stock or any shares of capital stock of MergerCo:

         (a) Each issued and outstanding share of Company Common Stock held by
     the Company as a treasury share or held by any direct or indirect Company
     Subsidiary and each issued and outstanding share of Company Common Stock
     owned by Parent, MergerCo or any other direct or indirect Parent Subsidiary
     immediately prior to the Effective Time, shall be canceled and retired and
     cease to exist without any conversion thereof and no payment or
     distribution shall be made with respect thereto.

         (b) Each share of Company Common Stock issued and outstanding
     immediately prior to the Effective Time, other than those shares referred
     to in Section 3.1(a), shall be canceled and shall be converted
     automatically into and represent the right to receive: (i) an amount equal
     to $3.00, net to the holder in cash, without any interest thereon (plus any
     cash in lieu of fractional shares as described in Section 4.1(e), the "Cash
     Consideration") and (ii) that number of fully paid and nonassessable shares
     of Parent Common Stock equal to $14.00 divided by the Base Stock Price (as
     defined below) (the "Exchange Ratio") (rounded to the nearest thousandth
     and subject to adjustment, as provided below, and subject to cash in lieu
     of fractional shares of Parent Common Stock, if any, pursuant to Section
     4.1(e), the "Stock Consideration" and together with the Cash Consideration,
     the "Merger Consideration").

         (c) The Exchange Ratio shall be adjusted as follows:

               (i) if the Average Parent Common Stock Price is greater than the
         Collar Percentage multiplied by the Base Stock Price (such product
         being the "Ceiling Stock Price"), then the Exchange Ratio shall be
         adjusted such that the aggregate value (based on the Average Parent
         Common Stock Price) of the Stock Consideration will be equal to the
         value the Stock Consideration would represent if the Average Parent
         Common Stock Price were equal to the Ceiling Stock Price and there were
         no adjustments to the Exchange Ratio as contemplated in this Section
         3.1. The Collar Percentage shall be equal to 119%, subject to the
         following adjustments: If (1) the Closing has not occurred on or prior
         to July 15, 2000, (2) subsequent to the date of this Agreement, Parent
         has engaged in a transaction (other than transactions contemplated by
         this Agreement or any transaction which would result in a Base
         Adjustment (as defined below)) (a "Parent Transaction") that would (x)
         require the approval of the stockholders of Parent or, (y) require
         Parent to include the information relating to such transaction in the
         pro forma financial statements (the "Pro Formas") that are required to
         be contained in the Registration

                                       A-9
<PAGE>   339

         Statement or (z) require Parent to amend or restate the Pro Formas in
         any material manner, and (3) all conditions to Closing have been
         satisfied (or waived by the party entitled to waive such condition) or
         are capable of being satisfied on such date with reasonable best
         efforts, other than the conditions set forth in Sections 9.1(a) and
         9.1(d) and the failure of either such condition to be satisfied is the
         result of a Parent Transaction, then, commencing on the later to occur
         of (i) July 16, 2000 and (ii) the first business day after which the
         circumstances set forth in clause (3) are present (such later date
         being the "Trigger Day") the Collar Percentage shall be increased as
         follows: 2.5 percentage points on the Trigger Day, and an additional
         five percentage points per each 31 day period (a "Monthly Period") (on
         a pro rata basis, based on the actual number of elapsed days in such
         Monthly Period at the Closing Date) beginning on the sixteenth calendar
         day following the Trigger Day;

               (ii) if the Average Parent Common Stock Price is equal to or
         greater than 69% of the Base Stock Price and less than 86% of the Base
         Stock Price (86% of the Base Stock Price being the "Floor Stock
         Price"), then the Exchange Ratio shall be adjusted such that the
         aggregate value (based on the Average Parent Common Stock Price) of the
         Stock Consideration will be equal to the value the Stock Consideration
         would represent if the Average Parent Common Stock Price were equal to
         the Floor Stock Price and there were no adjustments to the Exchange
         Ratio as contemplated in this Section 3.1; and

               (iii) subject to the provisions of Section 10.1(i), if the
         Average Parent Common Stock Price is less than 69% of the Base Stock
         Price, then the Exchange Ratio will equal that number that it would be
         set to in clause (ii) above if the Average Parent Common Stock Price
         were equal to 69% of the Base Stock Price.

         For purposes of this Agreement, the "Average Parent Common Stock Price"
     means the volume weighted average trading price of Parent Common Stock for
     ten randomly selected trading days out of the twenty (20) consecutive
     trading days ending with the last trading day prior to the Closing Date.
     The "Base Stock Price" shall be equal to $47.875, subject to the following
     "Base Adjustments": (i) if, after the date of this Agreement and on or
     prior to the Closing Date the outstanding shares of Parent Common Stock
     shall be changed into a different number of shares by reason of any
     reclassification, recapitalization, stock split, reverse stock split,
     combination or exchange of shares, or any dividend payable in Parent Common
     Stock shall be declared thereon with a record date within such period, or
     any similar event shall occur, the Base Stock Price shall be adjusted
     accordingly to provide to the shareholders of the Company the same economic
     effect as contemplated by this Agreement absent such reclassification,
     recapitalization, stock split, reverse stock split, combination, exchange,
     dividend or similar event; and (ii) if, after the date of this Agreement
     and on or prior to the Closing Date, Parent shall distribute to all holders
     of Parent Common Stock shares of capital stock of Parent other than Parent
     Common Stock, evidences of indebtedness or other assets

                                      A-10
<PAGE>   340

     (other than cash dividends out of current or retained earnings), or shall
     distribute to substantially all holders of Common Stock rights or warrants
     to subscribe for securities (other than those referred to in subsection (i)
     above), then in each such case the Base Stock Price shall be multiplied by
     a fraction of which the numerator shall be the Current Market Price (as
     defined below) of the Parent Common Stock on the record date less the then
     fair market value (as determined in good faith by the Board of Directors of
     Parent (the "Parent Board"), whose determination shall be conclusive
     evidence of such fair market value (absent manifest error or bad faith) and
     described in a board resolution) of the portion of the assets so
     distributed or of such subscription rights or warrants applicable to one
     share of Parent Common Stock and of which the denominator shall be the
     Current Market Price of the Parent Common Stock. The "Current Market Price"
     shall mean the volume weighted average trading price of Parent Common Stock
     for the ten randomly selected trading days out of the prior twenty (20)
     consecutive trading days. Parent may only effect a distribution described
     under (ii) above, if such distribution does not include operating assets
     that are required to maintain the current operating businesses of CoreComm,
     Inc. (a subsidiary of Parent) and the distribution of such operating assets
     would not have a material adverse effect on the current operating
     businesses of CoreComm, Inc., other than the local multipoint distribution
     service licenses and related assets.

         (d) If at any time prior to Closing, either the written opinion of
     counsel required to be received by the Company pursuant to Section 9.2(e)
     or the written opinion required to be received by Parent pursuant to
     Section 9.3(g) is not reasonably expected to be delivered in a form
     acceptable to the Company and Parent because less than 80% of the value of
     the Merger Consideration will be Stock Consideration (determined as of the
     Closing Date) and all other conditions to Closing set forth in Article IX
     have been satisfied (or waived by the party entitled to make such
     condition), then the Merger Consideration shall be adjusted by increasing
     the Stock Consideration and decreasing the Cash Consideration so that the
     Stock Consideration shall constitute 80% of the value of the Merger
     Consideration (determined as of the Closing Date) provided, that, after
     such adjustment, the Merger qualifies as a reorganization under the
     provisions of Section 368(a)(2)(E) of the Code.

         (e) Each share of common stock, par value $.01 per share, of MergerCo
     (the "MergerCo Common Stock") issued and outstanding immediately prior to
     the Effective Time shall be converted into one validly issued, fully paid
     and non-assessable share of common stock, par value $.01 per share, of the
     Surviving Corporation (the "Surviving Corporation Common Stock"),
     certificates for which shall be issued to the stockholders of MergerCo on a
     pro rata basis in accordance with their respective shares of MergerCo upon
     surrender to the Surviving Corporation of such stockholders' certificates
     formerly representing such shares of MergerCo Common Stock.

         (f) All shares of Company Common Stock, when converted as provided in
     Section 3.1(b), shall no longer be outstanding and shall automatically be
     canceled
                                      A-11
<PAGE>   341

     and retired and shall cease to exist, and each Certificate previously
     evidencing such shares shall thereafter represent only the right to receive
     the Merger Consideration and cash in lieu of fractional shares of Parent
     Common Stock in accordance with Sections 3.1(b) and 4.1(e) and any
     distribution or dividend under Section 4.1(c). The holders of Certificates
     previously evidencing shares of Company Common Stock outstanding
     immediately prior to the Effective Time shall cease to have any rights with
     respect to the Company Common Stock except as otherwise provided herein or
     by law and, upon the surrender of Certificates in accordance with the
     provisions of Article III hereof, shall only represent the right to receive
     for their shares of Company Common Stock the Merger Consideration and cash
     in lieu of fractional shares of Parent Common Stock in accordance with
     Sections 3.1(b) and 4.1(e) and any distribution or dividend under Section
     4.1(c) in each case without interest.

     3.2 Company Stock Options and Related Matters.

     (a) Each option (collectively, the "Company Options") granted under the
Company's Amended and Restated 1998 Stock Option and Incentive Plan (the
"Company Stock Option Plan"), which is outstanding (whether or not then
exercisable) as of immediately prior to the Effective Time and which has not
been exercised or canceled prior thereto, shall, at the Effective Time, be
assumed by Parent, subject to the provisions of this Section 3.2 (the "Assumed
Options"). The Assumed Options shall not terminate in connection with the Merger
and shall continue to have, and be subject to, the same terms and conditions as
set forth in the Company Stock Option Plan and agreements (as in effect
immediately prior to the Effective Time) pursuant to which the Company Options
were granted, provided that (i) all references to the Company shall be deemed to
be references to Parent and all references to shares of Company Common Stock
shall be deemed to be references to shares of Parent Common Stock, (ii) each
Company Option shall be exercisable for that number of whole shares of Parent
Common Stock equal to the product of the number of shares of Company Common
Stock covered by such Company Option immediately prior to the Effective Time
multiplied by the Option Exchange Ratio (as defined below) and rounded to the
nearest whole number of shares of Parent Common Stock and (iii) the exercise
price per share of Company Common Stock under such Company Option shall be equal
to the exercise price per share of Company Common Stock under the Company Option
divided by the Option Exchange Ratio and rounded to the nearest cent. Parent
shall (A) reserve for issuance the number of shares of Parent Common Stock that
will become issuable upon the exercise of such Assumed Options pursuant to this
Section 3.2, (B) promptly after the Effective Time issue to each holder of a
Company Option a document evidencing the assumption by Parent of the Company's
obligations with respect thereto under this Section 3.2, and (C) promptly after
the Effective Time, cause to be filed a registration statement on an appropriate
form under the Securities Act of 1933, as amended (the "Securities Act"),
relating to the Company Stock Option Plans then in effect and covering the
shares of Parent Common Stock issuable upon exercise of the Assumed Options. As
used in this Section 3.2, "Option Exchange Ratio" means the sum of

                                      A-12
<PAGE>   342

(i) the Exchange Ratio (as it may be adjusted) and (ii) the quotient obtained by
dividing the per share Cash Consideration by the Average Parent Common Stock
Price.

     (b) The adjustments provided in this Section 3.2 with respect to any
Company Options that are "incentive stock options" as defined in Section 422 of
the Code, shall be and are intended to be effected in a manner which is
consistent with Section 424(a) of the Code.

     (c) The parties to this Agreement shall take all reasonable action required
to exempt under SEC Rule 16(b)-3 the treatment of options contemplated hereby,
including, if necessary or appropriate, obtaining approvals, by each party's
Board of Directors, of the type described in a pertinent SEC no-action letter
dated January 12, 1999.

                                   ARTICLE IV

                               PAYMENT OF SHARES

     4.1 Payment for Shares of Company Common Stock.

     (a) From and after the Effective Time, such bank or trust company
designated by Parent, and reasonably acceptable to the Company, shall act as
exchange agent (the "Exchange Agent"). At or prior to the Effective Time,
MergerCo shall deposit, or MergerCo shall otherwise take all steps necessary to
cause to be deposited, with the Exchange Agent the aggregate Merger
Consideration and the cash in lieu of fractional shares of Parent Common Stock
(such aggregate Merger Consideration and cash in lieu of shares of Parent Common
Stock together with any dividends or distributions with respect thereto to which
the holders of Certificates may be entitled pursuant to Section 4.1(c) being
hereinafter referred to as the "Exchange Fund") to which holders of shares of
Company Common Stock shall be entitled pursuant to Section 3.1.

     (b) Promptly after the Effective Time, Parent shall cause the Exchange
Agent to mail to each holder of record of a Certificate or Certificates other
than the Company, Parent, MergerCo or any Parent Subsidiary (i) a letter of
transmittal which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration and cash in lieu of fractional shares of Parent Common Stock. Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed and completed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor (x) a certificate representing the number of whole
shares of Parent Common Stock representing the Stock Consideration to which such
holder shall be entitled, (y) a check representing the amount of the Cash
Consideration to which such holder shall be entitled and (z) a check
representing the amount of cash in lieu of fractional shares of Parent Common
Stock, if any, plus the amount of any dividends (other than stock dividends), or
distributions, if any, pursuant to paragraph (c) below, in the case of

                                      A-13
<PAGE>   343

(y) and (z), after giving effect to any required withholding tax, and the
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or accrued on the Cash Consideration or on cash payable in lieu of fractional
shares or on the dividend or distribution, if any, payable to holders of
Certificates pursuant to this Section 4.1. In the event of a transfer of
ownership of Company Common Stock which is not registered in the transfer
records of the Company, a Certificate representing the proper number of shares
of Parent Common Stock, together with checks for the Cash Consideration to which
such holder shall be entitled and for any cash to be paid in lieu of fractional
shares of Parent Common Stock plus, to the extent applicable, the amount of any
dividend or distribution, if any, payable pursuant to paragraph (c) below, may
be issued and paid to such a transferee if the Certificate representing shares
of such Company Common Stock is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and to evidence that
any applicable stock transfer taxes have been paid. If any certificate for
shares of Parent Common Stock is to be issued in a name other than that in which
the surrendered Certificate is registered, it shall be a condition of such
exchange that the person requesting such exchange shall pay any transfer or
other taxes required by reason of the issuance of certificates for shares of
Parent Common Stock in a name other than that of the registered holder of the
surrendered Certificate, or shall establish to the satisfaction of Parent or the
Exchange Agent that such tax has been paid or is not applicable.

     (c) Notwithstanding any other provisions of this Agreement, no dividends or
other distributions on Parent Common Stock shall be paid with respect to any
shares of Company Common Stock represented by a Certificate until such
Certificate is surrendered for exchange as provided herein; provided, however,
that subject to the effect of applicable laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificates representing
whole shares of Parent Common Stock issued in exchange therefor, without
interest, (i) at the time of such surrender, the amount of dividends or other
distributions with a record date after the Effective Time theretofore payable
with respect to such whole shares of Parent Common Stock and not paid, less the
amount of any withholding taxes which may be required thereon, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole shares of Parent
Common Stock, less the amount of any withholding taxes which may be required
thereon.

     (d) At and after the Effective Time, there shall be no transfers on the
stock transfer books of the Company of the shares of Company Common Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation, they
shall be canceled and exchanged for the Merger Consideration and cash in lieu of
fractional shares, if any, in accordance with this Section 4.1 (plus dividends
and distributions to the extent set forth in Section 4.1(c), if any).

     (e) No certificates or scrip representing fractional shares of Parent
Common Stock shall be issued upon the surrender for exchange of Certificates,
and such fractional share

                                      A-14
<PAGE>   344

interest will not entitle its owner to vote, to receive dividends or to any
other rights of a stockholder of Parent. In lieu of the issuance of any
fractional shares of Parent Common Stock pursuant to Section 3.1(b), the
Exchange Agent shall pay to each holder of shares of Company Common Stock
exchanged pursuant to the Merger who are entitled to receive a fraction of a
share of Parent Common Stock (after taking into account all Certificates
delivered by such holder) in accordance with the provisions of this Article IV,
an amount in cash equal to the product obtained by multiplying (A) the
fractional shares of Parent Common Stock to which such holder is entitled (after
taking into account all shares of Company Common Stock held at the Effective
Time) by (B) the closing price for a share of Parent Common Stock on NASDAQ on
the first business day immediately following the Effective Time.

     (f) Any portion of the Exchange Fund (including the proceeds of any
investments thereof and any shares of Parent Common Stock) that remains
unclaimed by the former stockholders of the Company one year after the Effective
Time shall be delivered to the Surviving Corporation. Any former stockholders of
the Company who have not theretofore complied with this Article IV shall
thereafter look only to the Surviving Corporation for payment of their Merger
Consideration and cash in lieu of fractional shares (plus dividends and
distributions to the extent set forth in Section 4.1(c), if any), as determined
pursuant to this Agreement, without any interest thereon. None of Parent,
MergerCo, the Company, the Exchange Agent or any other person shall be liable to
any former holder of shares of Company Common Stock for any amount properly
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws. If any Certificates shall not have been surrendered
prior to five years after the Effective Time (or immediately prior to such
earlier date on which any Merger Consideration in respect of such Certificate
would otherwise escheat to or become the property of any Governmental Entity (as
defined herein)), any amounts payable in respect of such Certificate shall, to
the extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interests of any person previously
entitled to those amounts. In the event any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent or the Surviving Corporation will issue and pay in exchange for
such lost, stolen or destroyed Certificate the Merger Consideration and cash in
lieu of fractional shares (plus, to the extent applicable, dividends and
distributions payable pursuant to Section 4.1(c)) in each case without interest.

     (g) Each of the Surviving Corporation and Parent shall be entitled to
deduct and withhold from any amounts otherwise payable pursuant to this
Agreement to any holder of a Certificate such amounts as it is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provisions of Law. To the extent that amounts are so withheld by the
Surviving Corporation or Parent, as the case may be, such withheld amounts shall
be treated for purposes of this Agreement as having been

                                      A-15
<PAGE>   345

paid to the holder of a Certificate in respect to which such deduction and
withholding was made by the Surviving Corporation or Parent, as the case may be.

                                   ARTICLE V

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the disclosure letter delivered at or prior to the
execution hereof to Parent, which shall refer to the relevant Sections of this
Agreement (the "Company Disclosure Schedule"), the Company represents and
warrants to Parent and MergerCo as follows:

     5.1 Existence; Good Standing; Authority; Compliance With Law.

     (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware. Except as set forth in
Section 5.1 of the Company Disclosure Schedule, the Company is duly licensed or
qualified to do business as a foreign corporation and is in good standing under
the laws of any other state of the United States in which the character of the
properties owned, leased or operated by it therein or in which the transaction
of its business makes such qualification or licensing necessary, except where
the failure to be so licensed or qualified would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on the
business, assets, properties, results of operations or financial condition of
the Company and the Company Subsidiaries (as defined herein) taken as a whole (a
"Company Material Adverse Effect"). The Company has all requisite corporate
power and authority to own, operate, lease and encumber its properties and carry
on its business as now conducted.

     (b) Each of the Company Subsidiaries is a corporation, partnership or
limited liability company (or similar entity or association in the case of those
Company Subsidiaries organized and existing other than under the laws of a state
of the United States) duly incorporated or organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation or
organization, has the corporate or other power and authority to own its
properties and to carry on its business as it is now being conducted, and is
duly qualified or licensed to do business and is in good standing in each
jurisdiction in which the character of the properties owned, leased or operated
by it therein or in which the transaction of its business makes such
qualification or licensing necessary, except as set forth in Section 5.1(b) of
the Company Disclosure Schedule and except for jurisdictions in which such
failures to be so qualified or to be in good standing would not, individually or
in the aggregate, reasonably be expected to have a Company Material Adverse
Effect.

     (c) Neither the Company nor any of the Company Subsidiaries is in violation
of any order of any court, Governmental Entity or arbitration board or tribunal,
or any domestic law, statute, order, judgment, decree, ordinance, rule or
regulation ("Law"), applicable to the Company or any Company Subsidiary or by
which any of their respective properties or assets is bound or affected, which
violations would, individually or in the aggregate, reasonably be expected to
have a Company Material Adverse Effect.

                                      A-16
<PAGE>   346

     (d) The Company and the Company Subsidiaries have obtained all franchises,
grants, authorizations, licenses, permits, easements, variances, exceptions,
consents, waivers, rights, certificates, approvals and orders of, and
registrations required to be made with, any United States (federal, state or
local) government, or governmental, regulatory or administrative authority,
agency or commission, court or arbitrator of competent jurisdiction or stock
exchange (each of the foregoing, a "Governmental Entity") that are material to
its business as it is now being or is intended to be conducted (the "Company
Permits"), except where failure to obtain any such Company Permit would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. The Company or one or more of the Company Subsidiaries
is in possession of all of the Company Permits, no material violations are or
have been recorded in respect of any of the Company Permits and no suspension or
cancellation of any of the Company Permits is pending or, to the knowledge of
the Company, threatened that has resulted or would be, individually or in the
aggregate, reasonably expected to result in a Company Material Adverse Effect.
Except for such defaults or violations that would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect, all
of the Company Permits are in full force and effect and neither the Company nor
any of its Subsidiaries is, or has received notice alleging that it is, in
conflict with, or in default or violation of, or, with the giving of notice or
lapse of time or both, would be in conflict with, or in default or violation of,
(i) any Law applicable to the Company or any of its Subsidiaries or by which any
property or asset of the Company or any of its Subsidiaries is bound or affected
by or (ii) any of the Company Permits.

     (e) The copies of the Company certificate of incorporation and by-laws,
each as amended through the date of this Agreement that are incorporated by
reference in, as exhibits to the Company's registration statement on Form S-8
dated August 12, 1999 and all comparable corporate organizational documents of
the Company Subsidiaries made available to Parent by the Company are complete
and correct copies of those documents. All such corporate organizational
documents of the Company and the Company Subsidiaries are listed on Section
5.1(e) of the Company Disclosure Schedule. Such certificate of incorporation and
by-laws and all comparable organizational documents of the Company Subsidiaries
are in full force and effect. The Company is not in violation of any of the
provisions of such certificate of incorporation or by-laws.

     (f) All Company Permits issued by a state public utilities commission or a
similar state regulatory body ("PUC") or the Federal Communications Commission
("FCC"), or a municipal authority used in conjunction with Company's provision
of telecommunications services (collectively, the "Communications Permits") are
listed in Section 5.1(f) of the Company Disclosure Schedule. Each of the
Communications Permits was duly issued and is valid and in full force and effect
and has not been modified, canceled, revoked, or conditioned in any adverse
manner except for such modifications, cancellations, revocations or conditions
that would not, individually or in the aggregate, reasonably be expected to have
a Company Material Adverse Effect. None of the Communications Permits has been
sold, conveyed, pledged, assigned or transferred to any other party, and no
other party has any present or future right to acquire use of

                                      A-17
<PAGE>   347

them that would in either case, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect.

     (g) Except as disclosed in Section 5.1(g) the Company Disclosure Schedule,
the Company has complied with and is in compliance with all regulations and laws
applicable to its operations under the Communications Permits, except where any
such failure would not, individually or in the aggregate, reasonably be expected
to have a Company Material Adverse Effect. The Company is in compliance with,
and its businesses have operated in compliance with, the Communications Act of
1934, as amended, FCC regulations, or any applicable state laws or regulations,
and has filed all tariffs, registrations and reports and paid all required fees,
including any renewal applications, required by the Communications Act of 1934,
as amended, or any applicable state regulations and has complied with the terms
of each such tariff or regulation, except where any such failure would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. There is no action, suit, investigation or other
proceeding pending or, to the Company's knowledge, threatened against the
Company which might adversely affect the Communications Permits, or the
assignment of the Communications Permits to Parent or MergerCo that would,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. No event has occurred with respect to the
Communications Permits which permits or, after notice or lapse of time, or both,
would permit revocation or termination thereof, or would result in any
impairment of the rights of the holder of the Communications Permits or the
imposition of a forfeiture against the Company or any subsequent holder of the
Communications Permits with respect to the operation of the facilities
authorized thereby that would, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect.

     (h) The Company has delivered to Parent correct and complete copies of (a)
the Company's Communications Permits and the applications related thereto
together with any pending applications filed by the Company for new or modified
facilities related to the purchased business, and (b) all other Permits and any
tariffs filed by the Company relating to the purchased business, and any
applications for additional or modified Permits to the purchased business,
except for those Communications Permits or other Permits that would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.

     5.2 Authorization, Validity and Effect of Agreements.   The Company has the
requisite power and authority to enter into the transactions and to execute and
deliver this Agreement. The Company Board has unanimously approved this
Agreement, the Merger and the other Transactions and has resolved to recommend
that the holders of Company Common Stock adopt and approve this Agreement at the
stockholders' meeting of the Company to be held in accordance with the
provisions of Section 8.1. In connection with the foregoing, the Company Board
has taken such actions and votes as are necessary on its part to render the
provisions of Section 203 of the DGCL and all other applicable takeover statutes
inapplicable to this Agreement, the Merger, the other Transactions and the
Voting Agreement. Subject only to the approval of this Agreement

                                      A-18
<PAGE>   348

by the holders of a majority of the outstanding shares of Company Common Stock
(the "Requisite Company Vote"), the execution by the Company of this Agreement
and the consummation of the Transactions have been duly authorized by all
requisite corporate action on the part of the Company and no other corporate
proceedings on the part of the Company are necessary to authorize this Agreement
or to consummate the Transactions. As of the date hereof, all of the directors
and executive officers of the Company have indicated that they presently intend
to vote all shares of the Company Common Stock which they own to approve this
Agreement and the Transactions at the stockholders' meeting of the Company to be
held in accordance with the provisions of Section 8.1. This Agreement, assuming
due and valid authorization, execution and delivery thereof by Parent,
constitutes a valid and legally binding obligation of the Company, enforceable
against the Company in accordance with its terms, subject to applicable
bankruptcy, insolvency, moratorium or other similar laws relating to creditors'
rights and general principles of equity.

     5.3 Capitalization.

     (a) The authorized capital stock of the Company consists of 50,000,000
shares of Company Common Stock and 5,000,000 shares of preferred stock, par

Company Preferred Stock were held in the treasury of the Company. All such
issued and outstanding shares of capital stock of the Company are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights. As of the date of this Agreement, no shares of capital stock or voting
securities of the Company were issued, outstanding or reserved for issuance by
the Company or outstanding other than as described above and, since such date,
no shares of capital stock or other voting securities or options in respect
thereof have been issued except upon the exercise of the Company Options
outstanding on such date. The Company has no outstanding bonds, debentures,
notes or other obligations the holders of which have the right to vote (or which
are convertible into or exercisable for securities having the right to vote)
with the stockholders of the Company on any matter. Except for the Company
Options (all of which have been issued under the Company Stock Option Plan),
there are no existing options, warrants, calls, subscriptions, convertible
securities, redemption rights, or other rights, agreements or commitments to
which the Company is a party or by which the Company is bound relating to the
issued or unissued capital stock of, other equity interests in, or securities
exchangeable for or convertible into capital stock or other equity interests in,
the Company or any Company Subsidiary or any Company Subsidiary which obligate
the Company to issue, transfer or sell any shares of capital stock of the
Company.

shares of capital stock of the Company or which restrict the transfer of any
such shares, nor does the Company have knowledge of any third party agreements
or understandings with respect to the voting of any such shares or which
restrict the transfer of any such shares. Except as set forth in Section 5.3 of
the Company Disclosure Schedule, there are no outstanding contractual
obligations of the Company or any Company Subsidiary to repurchase, redeem or
otherwise acquire any shares of capital stock, partnership interests or any
other securities of the Company or any Company Subsidiary. Except as set forth

of any agreement to register the offer and sale or resale of any of their
securities under the Securities Act.

     5.4 Subsidiaries.   The Company owns directly or indirectly each of the
outstanding shares of capital stock or other equity interest of each of the
Company Subsidiaries. Each of the outstanding shares of capital stock of each of
the Company Subsidiaries having corporate form is duly authorized, validly
issued, fully paid and nonassessable. Except as set forth in Section 5.4 of the
Company Disclosure Schedule, each of the outstanding shares of capital stock or
other equity interest of each of the Company Subsidiaries is owned, directly or
indirectly, by the Company free and clear of all liens, pledges, security
interests, claims, options, rights of first refusal, agreements, limitations on
the Company or such other Company's voting rights, charges or other encumbrances

securities), other than in any Company Subsidiary.

     5.6 No Violation; Consents.

     (a) Except as set forth in Section 5.6(a) of the Company Disclosure
Schedule, neither the execution and delivery by the Company of this Agreement
nor consummation by the Company of the Transactions in accordance with the terms
hereof, will conflict with or result in a breach of any provisions of the
Company Certificate or the Company

                                      A-20
<PAGE>   350

Except as set forth in Section 5.6(a) of the Company Disclosure Schedule, the
execution and delivery by the Company of this Agreement and consummation by the
Company of the Transactions in accordance with the terms hereof will not
violate, or conflict with, or result in (x) a violation of any Law applicable to
the Company or any Company Subsidiary or by which any property or asset of the
Company or any Company Subsidiary is bound or affected or (y) any provision of,
or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under, or result in the termination or in a
right of termination or cancellation of, or accelerate the performance required
by, or result in the creation of any Lien, upon any of the properties or assets
of the Company or the Company Subsidiaries under, or result in being declared
void, voidable or without further binding effect, any of the terms, conditions
or provisions of any note, bond, mortgage, indenture, deed of trust, license,
franchise, permit, lease, contract, agreement or other instrument, commitment or
obligation (collectively, "Contracts") to which the Company or any of the
Company Subsidiaries is a party, or by which the Company or any of the Company
Subsidiaries or any of their properties is bound, except in each such case as

approval or authorization of, or declaration, filing or registration with, any
Governmental Entity, except where the failure to obtain any such consent,
approval or authorization of, or declaration, filing or registration with, any
governmental or regulatory authority would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.

Subsidiaries are a party or by which they or their assets or properties is bound
or affected under which consents or waivers are required prior to consummation

                                      A-21
<PAGE>   351

were prepared in accordance with the applicable requirements of the Exchange
Act, the Securities Act and the rules and regulations promulgated thereunder
(the "Securities Laws"). All required Company SEC Reports have been filed with
the SEC and constitute all forms, reports, exhibits, schedules, statements and
other documents required to be filed by the Company under the Securities Laws
since July 21, 1999. As of their respective dates, the Company SEC Reports,

applicable requirements of the Securities Laws and (ii) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements made therein, in the light
of the circumstances under which they were made, not misleading. Each of the
consolidated balance sheets of the Company included in or incorporated by
reference into the Company SEC Reports (including the related notes and
schedules) fairly presents the consolidated results of operations and cash flow
of the Company and the Company Subsidiaries as of its date and each of the
consolidated statements of income, retained earnings and cash flows of the
Company included in or incorporated by reference into the Company SEC Reports
(including any related notes and schedules) fairly presents the results of
operations, retained earnings or cash flows, as the case may be, of the Company
and the Company Subsidiaries for the periods set forth therein (subject, in the
case of unaudited statements, to normal year-end audit adjustments which would
not be material in amount or effect), in each case in accordance with generally
accepted accounting principles consistently applied during the periods involved,
except as may be noted therein and except, in the case of the unaudited
statements, as permitted by Form 10-Q pursuant to Section 13 or 15(d) of the
Exchange Act. All of such balance sheets and statements complied as to form in
all material respects with applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto. No Company
Subsidiary is subject to the periodic reporting requirements of the Exchange Act
or is otherwise required to file any documents with the SEC or any national
securities exchange or quotation service or comparable Governmental Entity.

     (b) Except as and to the extent set forth on the consolidated balance sheet
of the Company and the consolidated Company Subsidiaries as of September 30,
1999 including the related notes, neither the Company nor any Company Subsidiary
has any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) that would be required to be reflected on a balance
sheet or in the related notes prepared in accordance with generally accepted
accounting principles, except for liabilities or obligations incurred in the
ordinary course of business since September 30, 1999 that have not resulted and
would not, individually or in the aggregate, reasonably be expected to have a
Company Material Adverse Effect.

     5.8 Litigation.   Except as set forth in Section 5.8 of the Company
Disclosure Schedule, there is no litigation, suit, claim, action or proceeding
pending or, to the knowledge of the Company, threatened against the Company or
any of the Company Subsidiaries, as to which there is a reasonable likelihood of
an adverse determination and which, if adversely determined, would, individually
or in the aggregate, reasonably be

                                      A-22
<PAGE>   352

expected to have a Company Material Adverse Effect. Neither the Company nor any
Company Subsidiary is subject to any outstanding order, writ, injunction or
decree which has resulted or would, individually or in the aggregate, reasonably
be expected to result in a Company Material Adverse Effect.

     5.9 Absence of Certain Changes.   Except as disclosed in the Company SEC
Reports filed with the SEC between September 30, 1999 and the date of this
Agreement or in Section 5.9 of the Company Disclosure Schedule, since September
30, 1999 the Company and the Company Subsidiaries have conducted their
businesses only in the ordinary course of business and there has not been:

         (a) any declaration, setting aside or payment of any dividend or other
     distribution with respect to Company Common Stock or any redemption,
     purchase or other acquisition of the Company's securities;

         (b) any material commitment, contractual obligation (including, without
     limitation, any management or franchise agreement, any lease (capital or
     otherwise) or any binding letter of intent), borrowing, liability,
     guaranty, capital expenditure or transaction (each, a "Commitment") entered
     into by the Company or any of the Company Subsidiaries outside the ordinary
     course of business except for Commitments for expenses of attorneys,
     accountants and investment bankers incurred in connection with the
     Transactions;

         (c) any material change in the Company's accounting principles,
     practices or methods;

         (d) any damage, destruction or other casualty loss with respect to any
     asset or property owned, leased or otherwise used by it or any Company
     Subsidiaries, whether or not covered by insurance, which damage,
     destruction or loss, individually or in the aggregate, has resulted or
     would, individually or in the aggregate, reasonably be expected to have a
     Company Material Adverse Effect;

         (e) any increase in the compensation or benefits or establishment of
     any bonus, insurance, severance, deferred compensation, pension,
     retirement, profit sharing, stock option (including, the granting of stock
     options, stock appreciation rights, performance awards or restricted stock
     awards), stock purchase or other employee benefit plan, or any other
     increase in the compensation payable or to become payable to any executive
     officers of the Company or any Company Subsidiary except in the ordinary
     course of business consistent with past practice or except as required by
     applicable Law or pursuant to agreements in effect as of September 30,
     1999;

         (f)(A) any material incurrence or assumption by the Company or any
     Company Subsidiary of any indebtedness for borrowed money or (B) any
     guarantee, endorsement or other incurrence or assumption of material
     liability (whether directly, contingently or otherwise) by the Company or
     any Company Subsidiary for the obligations of any other person (other than
     any wholly-owned Company Subsidiary), other than in the ordinary course of
     business consistent with past practice;

                                      A-23
<PAGE>   353

         (g) any creation or assumption by the Company or any Company Subsidiary
     of any Lien on any material asset of the Company or any Company Subsidiary,
     other than in the ordinary course of business consistent with past
     practice;

         (h) any making of any loan, advance or capital contribution to or
     investment in any person by the Company or any Company Subsidiary, other
     than in the ordinary course of business consistent with past practice or in
     an amount which are not in the aggregate in excess of $100,000;

         (i)(A) any Contract or agreement entered into by the Company or any
     Company Subsidiary on or prior to the date hereof relating to any material
     acquisition or disposition of any assets or business or (B) any
     modification, amendment, assignment or termination of or relinquishment by
     the Company or any Company Subsidiary of any rights under any other
     Contract (including any insurance policy naming it as a beneficiary or a
     loss payable payee) that has resulted or would, individually or in the
     aggregate, reasonably be expected to result in a Company Material Adverse
     Effect other than transactions, commitments, contracts or agreements in the
     ordinary course of business consistent with past practice or those
     contemplated by this Agreement; or

         (j) the circuits identified in Section 5.19(c) of the Company
     Disclosure Schedule have not been materially altered or otherwise changed
     in any manner that would, individually or in the aggregate, reasonably be
     expected to have a Company Material Adverse Effect.

     5.10 Taxes.

     (a) Except as set forth in Section 5.10 of the Company Disclosure Schedule,
each of the Company and the Company Subsidiaries (i) has filed, or will have
filed, all Tax Returns (as defined below) required to be filed by it on or
before the Closing Date (taking into account any applicable extensions) and all
such Tax Returns are true, correct and complete in all material respects, and
(ii) has paid, or will have paid, all Taxes (as defined below) required to be
paid by it on or before the Closing Date (whether or not shown on any Tax
Return), except, in each case, where the failure to file such Tax Returns or pay
such Taxes would not, individually or in the aggregate, reasonably be expected
to have a Company Material Adverse Effect. Except as set forth in Section 5.10
of the Company Disclosure Schedule, the most recent audited financial statements
contained in the Company's Quarterly Report on Form 10-Q for the quarter year
ended September 30, 1999 reflect an adequate reserve for all material Taxes
payable by the Company and the Company Subsidiaries for all taxable periods and
portions thereof through the date of such financial statements in accordance
with United States generally accepted in accounting principles ("GAAP"). To the
knowledge of the Company, and except as set forth in Section 5.10 of the Company
Disclosure Schedule, no deficiencies for any Taxes have been proposed, asserted
or assessed against the Company or any of the Company Subsidiaries, there are no
Tax liens on any assets of the Company or of any of the Company Subsidiaries
(other than Liens for current Taxes not yet due), and no requests for waivers of
the time to assess any such Taxes are pending. Section 5.10 of the Company
Disclosure Schedule lists all (A) Tax sharing
                                      A-24
<PAGE>   354

allocation or indemnification agreements and (B) agreements for exemptions with
Governmental Entities to which the Company or any of the Company Subsidiaries is
a party.

     (b) Except as set forth on Schedule 5.10 of the Company Disclosure
Schedule, neither the Company nor any of the Company Subsidiaries has been a
member of any "affiliated group" (as defined in section 1504(a) of the Code)
other than the affiliated group of which the Company is the "parent" and, except
with respect to any group of which only the Company and/or its Subsidiaries are
members, is not subject to Treas. Reg. Section 1.1502-6 (or any similar
provision under foreign, state or local law) for any period. Except as set forth
on Schedule 5.10 of the Company Disclosure Schedule, neither the Company nor any
of the Company Subsidiaries has been required to include in income any
adjustment pursuant to Section 481 of the Code (or any similar provision of
state, local or foreign tax law) by reason of a voluntary change in accounting
method initiated by the Company or any of the Company Subsidiaries, and to the
knowledge of the Company the Internal Revenue Service has not initiated or
proposed any such adjustment or change in accounting method. Except as set forth
on Schedule 5.10 of the Company Disclosure Schedule, no closing agreement that
could affect the Taxes of the Company or any of the Company Subsidiaries for
periods ending after the Effective Time pursuant to Section 7121 of the Code (or
any predecessor provision) or any similar provision of any state, local or
foreign law has been entered into by or with respect to the Company or any of
the Company Subsidiaries. Except as set forth on Schedule 5.10 of the Company
Disclosure Schedule, there is no contract, agreement, plan or arrangement
covering any person that, individually or collectively, could give rise to the
payment of any amount that would not be deductible by the Company or any of the
Company Subsidiaries by reason of Section 162(m) or Section 280G of the Code and
neither the Company nor any of the Company Subsidiaries has made or expects to
make any such payments. Neither the Company nor any of the Company Subsidiaries
is, or has been, a United States real property holding corporation (as defined
in Section 897(c)(2) of the Code) during the applicable period specified in
Section 897(c)(1)(A)(ii) of the Code.

     (c) For purposes of this Agreement, "Taxes" means all federal, state, local
and foreign income, property, sales, franchise, employment, excise, use,
franchise, capital stock, withholding, payroll, gross receipts, value added,
transfer and gains and other taxes, tariffs or governmental charges of any
nature whatsoever, together with any interest, penalties or additions to Tax
with respect thereto.

     (d) For purposes of this Agreement, "Tax Returns" means all reports,
returns, declarations, statements or other information required to be supplied
to a domestic or foreign taxing authority in connection with Taxes.

     5.11 Real Property Leases; Properties.

     (a) Section 5.11 of the Company Disclosure Schedule is a true and correct
Schedule of all real property leased, subleased, licensed or occupied or used by
the Company or any Company Subsidiary under any agreements, other than point-of-
presence related agreements ("POP Agreements"), (collectively, the "Leases") to
or by
                                      A-25
<PAGE>   355

the Company or any of the Company Subsidiaries (collectively, the "Real
Property") and lists the dates of and parties to each such Lease, the dates and
parties to each amendment, modification, supplement to such Lease, the term of
such Lease, any extension and expansion options, and the rent payable
thereunder. Neither the Company nor any Company Subsidiary owns any real
property. The Company has delivered to Parent complete and accurate copies of
the Leases (as amended to date).

     (b) With respect to each of the Leases, except as would not, individually
or in the aggregate, reasonably be expected to have a Company Material Adverse
Effect:

         (i) each Lease is legal, valid, binding, enforceable obligation of the
     Company;

         (ii) each Lease will continue to be legal, valid, binding, enforceable
     obligation of the Company immediately following the Closing in accordance
     with the terms thereof as in effect immediately prior to the Closing;

         (iii) neither the Company nor, to the knowledge of the Company, any
     other party, is in material breach or violation of, or default under, any
     such Lease, and, to the knowledge of the Company, no event has occurred, is
     pending or, is threatened, which, after the giving of notice, with lapse of
     time, would constitute a material breach or default by the Company or, to
     the knowledge of the Company, any other party under such Lease nor has any
     termination event or on condition occurred under the Leases;

         (iv) the Company has not assigned, transferred, conveyed, mortgaged,
     deeded in trust or encumbered any interest in the leasehold or
     subleasehold;

         (v) to the knowledge of the Company, there are no Liens, easement,
     covenant or other restriction applicable to the Real Property, except for
     recorded easements, covenants and other restrictions which do not
     materially impair the current uses or the occupancy by the Company of the
     property subject thereto;

         (vi) neither the Company nor any Company Subsidiary thereof has any
     ownership, financial or other interest in the landlord under any Lease;

         (vii) there are no Leases granting to any person or entity other than
     the Company or any of the Company Subsidiaries any right to the possession,
     use, occupancy or enjoyment of the Real Property, or any portion thereof;

         (viii) there is no underlying mortgage, deed of trust, lease, grant of
     term or other estate in or interest affecting any Real Property which is
     superior to the interest of the Company and the Company Subsidiaries, as
     tenants under the applicable Lease; and

         (ix) except for as disclosed in Section 5.11(c) of the Company
     Disclosure Schedule or easements, rights-of-way and other non-monetary
     encumbrances of a minor nature that do not individually or in the aggregate
     (i) interfere in any material respect with, or materially increase the cost
     of, the use, occupancy or operation of the applicable parcel of Real
     Property as currently used, occupied and operated or (ii) materially reduce
     the fair market value of the applicable parcel of

                                      A-26
<PAGE>   356

     Real Property below the fair market value such parcel would have had but
     for such encumbrances, the Real Property is free and clear of all liens,
     pledges, mortgages, deeds of trust, security interests, claims, leases,
     licenses, charges, options, rights of first refusal, easements, servitudes,
     transfer restrictions, encumbrances, restrictive covenants, encroachment or
     other survey defect or any other restriction or limitation whatsoever and
     the Company or one of the Company Subsidiaries holds the leasehold estate
     and interest in each Lease free and clear of all liens, pledges, mortgages,
     deeds of trust, security interests, claims, leases, licenses, charges,
     options, rights of first refusals, easements, servitudes, transfer
     restrictions, encumbrances or any other restriction or limitation
     whatsoever.

     (c) All of the land, buildings, structures and other improvements used by
the Company and the Company Subsidiaries in the conduct of their businesses are
included in the Real Property, except for such land, buildings, structures and
other improvements that would not, in the aggregate, reasonably be expected to
have a Company Material Adverse Effect.

     (d) Each of the POP Agreements of the Company and the Company Subsidiaries
constitute legal, valid, binding, enforceable obligation of the Company and will
continue to be legal, valid, binding, enforceable obligation of the Company
immediately following the Closing in accordance with the terms thereof as in
effect immediately prior to the Closing, except for those the absence of which
would not in the aggregate reasonably be expected to have a Company Material
Adverse Effect. Neither the Company nor any Company Subsidiary, nor to the
Company's knowledge, any other person, is in violation of or in default under
(nor does there exist any condition which with the passage of time or the giving
of notice would cause such a violation of or default under) any POP Agreement to
which the Company or a Company Subsidiary is a party or by which it or any of
its properties or assets is bound or affected, except for violations or defaults
that have not resulted and would not, in the aggregate, reasonably be expected
to have a Company Material Adverse Effect.

     (e) Except as set forth in Section 5.11(f) of the Company Disclosure
Schedule, the Company and the Company Subsidiaries own good and marketable
title, free and clear of all Liens, to all of the property and assets shown on
the Company's balance sheet at September 30, 1999 as reflected in the Company
SEC Reports (the "Company Balance Sheet") or acquired after September 30, 1999,
except for (A) assets which have been disposed of to nonaffiliated third parties
since September 30, 1999 in the ordinary course of business, (B) Liens reflected
in the Company Balance Sheet, (C) Liens or imperfections of title which are not,
individually or in the aggregate, material in character, amount or extent and
which do not materially detract from the value or materially interfere with the
present or presently contemplated use of the assets subject thereto or affected
thereby, and (D) Liens for current Taxes not yet due and payable. All of the
machinery, equipment and other tangible personal property and assets owned or
used by the Company and the Company Subsidiaries are, to the Company's
knowledge, in good condition and repair, except for ordinary wear and tear not
caused by neglect, and are useable in the ordinary course of business.

     5.12 Intellectual Property.

     (a) Section 5.12(a) of the Company Disclosure Letter sets forth all United
States and foreign patents and patent applications, trademark and service mark
registrations and applications, Internet domain name registrations and

the Company and material to the business of the Company and the Company
Subsidiaries, taken as a whole, as conducted as of the date hereof, specifying

Agreement, "Intellectual Property" means all of the following as they exist in
all jurisdictions throughout the world, in each case, to the extent owned by,
licensed to, or otherwise used by the Company or any Company Subsidiaries or, as
applicable, Parent or any Parent Subsidiary: (A) patents, patent applications,

marks, trade dress, trade names, brand names, Internet domain names, designs,
logos, or corporate names, whether registered or unregistered, and all

clear of any Liens, or a licensee under a valid sufficient license for, all
Intellectual Property that is material to the business of the Company and the
Company Subsidiaries conducted as of the date hereof, taken as a whole. Except
as disclosed in the Company SEC Reports or Section 5.12(c) of the Company
Disclosure Schedule, there are no claims pending or, to the Company's knowledge,
threatened, that the Company or any Company Subsidiary is in violation of any
such intellectual property right of any third party or that challenges the
validity, enforceability, ownership, or right to use, sell, or license any
Intellectual Property which would, individually or in the aggregate, reasonably
be expected to have a Company Material Adverse Effect, and, to the Company's
knowledge, no third party is in violation of any intellectual property rights of
the Company or any Company Subsidiary which would, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.

     (d) The Company and/or one or more of its Subsidiaries owns, or is licensed
or otherwise possesses valid rights to use, all material computer software
programs or applications, including the Company's web-based customer care and
billing system, and other tangible or intangible proprietary information or
materials (the "Software") that are used in the business of the Company and the
Company Subsidiaries as conducted as of the date hereof, except for software
that is "off the shelf" or "shrink-wrapped" and except for any such failures to
own, be licensed or possess that would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect. In addition to
the foregoing, as to the Company's web-based customer care and billing system,
the Company owns all source code, object code, and documents related thereto,
except as would not reasonably be expected to have a Company Material Adverse
Effect. The Software performs in conformance with its documentation and is fully
and freely transferable to Parent without any third party consents, except for
failures to perform or to be fully and freely transferable that, individually or
in the aggregate, have not resulted and would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Effect on the
Company.

     5.13 Environmental Matters.   The Company and the Company Subsidiaries are
and have been in compliance with all Environmental Laws (as defined below),
except for any noncompliance that would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect. As used in
this Agreement, "Environmental Laws" shall mean all federal, state and local
laws, rules, regulations, ordinances and orders that regulate the release of
hazardous substances or other pollutants or contaminants into the environment,
or impose requirements relating to environmental protection, pollution or health
and safety. As used in this Agreement, "Hazardous Materials" means any
"hazardous waste" as defined in either the United States Resource Conservation
and Recovery Act or regulations adopted pursuant to said act, any "hazardous
substances" or "hazardous materials" as defined in the United States
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")
and, to the extent not included in the foregoing, any oil or fractions thereof,
pollutants or contaminants. Except as set forth in Section 5.13 of the Company
Disclosure Schedule, there is no administrative or judicial enforcement
proceeding or other claim, demand, order, decree or judgment pending, or to the
knowledge of the Company, threatened against the Company or any Company
Subsidiary under any Environmental Law. Except as set forth in Section 5.13 of
the Company Disclosure Schedule, neither the Company nor any Subsidiary or, to
the knowledge of the Company, any legal predecessor of the Company or any
Subsidiary, has received any written notice that it is potentially responsible
under any Environmental Law for response costs or natural resource damages, as
those terms are defined under the Environmental Laws, at any location and
neither the Company nor any Subsidiary has transported or disposed of, or
arranged for any third party to transport or dispose of, any Hazardous Materials
at any location included on the National Priorities List, as defined under
CERCLA or any location proposed for inclusion on that list or at any location on
any analogous state list. Except as set forth in Section 5.13 of the Company
Disclosure Schedule, (i) the Company has no knowledge of any release on the real
property owned

                                      A-29
<PAGE>   359

or leased by the Company or any Company Subsidiary or predecessor entity of
Hazardous Materials in a manner that could result in an order to which the
Company or any Company Subsidiary is subject to perform a response action or in
material liability to the Company or any Company Subsidiary under the
Environmental Laws, and (ii) to the Company's knowledge, there is no hazardous
waste treatment, storage or disposal facility, underground storage tank,
landfill, surface impoundment, underground injection well, friable asbestos or
PCB's, as those terms are defined under the Environmental Laws, located at any
of the real property owned or leased by the Company or any Company Subsidiary or
predecessor entity or facilities utilized by the Company or the Company
Subsidiaries in a condition likely to result in material liability to the
Company or any Company Subsidiary under Environmental Laws.

     5.14 Employee Benefit Plans.

     (a) Section 5.14(a) of the Company Disclosure Schedule sets forth a list of
every Benefit Plan (as hereinafter defined) that is maintained by the Company or
an Affiliate (as hereinafter defined) on the date hereof (each a "Company
Benefit Plan").

     (b) Each Company Benefit Plan which has been intended to qualify under
Section 401(a) of the Code, has received a favorable determination or approval
letter from the Internal Revenue Service ("IRS") regarding its qualification
under such section, its related trust has been determined to be exempt from
taxation under Section 501(a) of the Code, and nothing has occurred since the
date of such letter that has or is likely to adversely affect such qualification
or exemption. Each Company Benefit Plan that requires registration with a
government body has been so registered.

     (c) With respect to any Company Benefit Plan, there has been no event in
that could subject, directly or indirectly, the Company or any Affiliate or any
Company Benefit Plan to any material liability under ERISA, the Code or any
other law, regulation or governmental order applicable to any Company Benefit
Plan, including, without limitation, Section 406, 409, 502(i), 502(l) or 4069 of
ERISA, or Section 4971, 4975 or 4976 of the Code, or under any agreement,
instrument, statute, rule of law or regulation pursuant to or under which the
Company or any Affiliate has agreed to indemnify any person against liability
incurred under, or for a violation or failure to satisfy the requirement of, any
such statute, regulation or order. Except as set forth on Section 5.14(b) of the
Company Disclosure Schedule, there are no actions, liens, suits or claims
pending or, to the knowledge of the Company or any Affiliate, threatened (other
than routine claims for benefits) with respect to any Company Benefit Plan as to
which the Company or any Affiliate has or could reasonably be expected to have
any direct or indirect actual or contingent material liability. No litigation or
governmental administrative proceeding (or investigation) or other proceeding
(other than those relating to routine claims for benefits) is pending or, to the
Company's knowledge, threatened with respect to any such Company Benefit Plan.

     (d) Neither the Company nor any Affiliate maintains or has any obligation
to contribute to, or has within the preceding six years maintained or
contributed to, or has had during such period the obligation to maintain or
contribute to, or may have any liability with respect to, any Company Benefit
Plan subject to Title IV of ERISA,
                                      A-30
<PAGE>   360

Section 412 of the Code, any Multiemployer Plan or any "multiple employer plan"
within the meaning of the Code or ERISA or the regulations promulgated
thereunder.

     (e) Except as provided in Section 5.14(c) of the Disclosure Schedule,
neither the Company nor any Affiliate is a party to any plan or agreement that
will, as a result of the consummation of the transactions contemplated by this
Agreement or otherwise, (i) result in the acceleration of the time for payment
or vesting of, or increase the amount of compensation due to any employee,
former employee, consultant or independent contractor, (ii) reasonablely be
expected to result in any "excess parachute payment" under Section 280G of the
Code or any payment which is non-deductible under Section 162(m) of the Code.
The consummation of the transactions contemplated by this Agreement will not
entitle any employee or former employee to severance pay or similar payment
which payments, individually or in the aggregate, would be material to the
Company and the Company Subsidiaries.

     (f) Neither the Company nor any Affiliate has an announced plan or legally
binding commitment to create any additional Company Benefit Plans or to amend or

between the Company and any Company Subsidiary), which involve aggregate
payments by or to the Company or any Company Subsidiary (including, without
limitation, payments pursuant to a guaranty of any obligations of any Company
Subsidiary or third party) of $100,000 or more, whether or not made in the

<PAGE>   363

     (b) Except for the Company Contracts or as set forth in Section 5.19(b) of
the Company Disclosure Schedule, there is no Contract that is material to the
business, results of operations, assets, properties or financial condition of
the Company and the Company Subsidiaries taken as a whole. Each of the Company
Contracts constitutes a valid and legally binding obligation of the Company or
such Company Subsidiary and, to the knowledge of the Company, of the other
parties thereto, enforceable in accordance with its terms, and is in full force
and effect, except to the extent the failure to be so valid, binding or
enforceable, has not and would not, individually or in the aggregate, reasonably
be expected to have a Company Material Adverse Effect. Neither the Company nor
any Company Subsidiary, nor to the Company's knowledge, any other person, is in
violation of or in default under (nor does there exist any condition which with
the passage of time or the giving of notice would cause such a violation of or
default under) any Contract to which the Company or a Company Subsidiary is a
party or by which it or any of its properties or assets is bound or affected,
except for violations or defaults that have not resulted and would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. The Company has satisfied all volume commitment
requirements under the applicable Company Contracts to allow for the most
favorable pricing structure to be provided to the Company under such Company
Contracts. Set forth in Schedule 5.19(b), the Company Disclosure Letter is a
description of any material changes to the amount and terms of the indebtedness
of the Company and the consolidated Company Subsidiaries as described in the
notes to the financial statements set forth as incorporated by reference in the
Company's Quarterly Report on Form 10-Q for the quarter ended September 30,
1999. The aggregate amount of indebtedness of the Company and the Company
Subsidiaries which is outstanding under the Amended and Restated Credit
Agreement, dated as of July 26, 1999, among Voyager Information, Inc., Fleet
National Bank, as agent and certain lenders, is no more than $23,750,000.

     (c) Section 5.19(c) of the Company Disclosure Schedule sets forth a true
and complete list as of February 1, 2000 of all circuit and related agreements
and any amendments, supplements or other modifications thereto except for those
circuit and related agreements that would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect.

     5.20 Certain Agreements.   Except as set forth in Section 5.20 of the
Company Disclosure Letter, neither the Company nor any of the Company
Subsidiaries is a party to any oral or written (i) agreement with any executive
officer or other key employee of the Company or Company Subsidiary the benefits
of which are contingent, or the terms of which are materially altered, upon the
occurrence of a transaction involving the Company of the nature contemplated by
this Agreement, or agreement with respect to any executive officer of the
Company providing any term of employment or compensation guarantee (x) extending
for a period longer than one year after the Effective Time or (y) for the
payment of in excess of $100,000 or (ii) plan or arrangements, including any
stock option plan, stock appreciation right plan, restricted stock plan or stock
purchase plan, any of the benefits of which will be increased, or the vesting of
the benefits of which will be accelerated, by the occurrence of any of the

                                      A-34

of which will be calculated on the basis of any of the transactions contemplated
by this Agreement.

     5.21 Subscribers.   The Company has at least 325,000 subscribers as
calculated in accordance with the Company's customary practices. As used herein,
the term "Subscriber" means a customer of the Company or a Company Subsidiary
who (i) is currently connected to and receiving Internet access service from the
system and (ii) is being charged and is paying for such service. Notwithstanding
the foregoing, it shall not be deemed to be a reduction in the number of
Subscribers if a Subscriber continues to remain as a customer of the Company,
even though such Subscriber has been aggregated with one or more other
Subscribers into one account.

     5.22 Information.   None of the information to be supplied by the Company
for inclusion or incorporation by reference in the Proxy Statement or the Form
S-4 will, in the case of the Form S-4, at the time it becomes effective and at
the Effective Time, contain any untrue statement of a material fact or omit to
state any material fact required to be stated in that Form S-4 or necessary to
make the statements in that Form S-4 not misleading, or, in the case of the
Proxy Statement or any amendments of or supplements to the Proxy Statement, at
the time of the mailing of the Proxy Statement and any amendments of or
supplements to the Proxy Statement and at the time of the Company Stockholders
Meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated in that Proxy Statement or necessary in
order to make the statements in that Proxy Statement, in light of the
circumstances under which they are made, not misleading. The Proxy Statement
(except for those portions of the Proxy Statement that relate only to Parent or
Parent Subsidiaries or affiliates of Parent) will comply as to form in all
material respects with the provisions of the Exchange Act.

     5.23 Vote Required.   The Requisite Company Vote is the only vote of the
holders of any class or series of the Company's capital stock necessary (under
the Company Certificate and Company By-laws, the DGCL, other applicable Law or
otherwise) to approve this Agreement, the Merger or the other Transactions.

     5.24 Definition of the Company's Knowledge.   As used in this Agreement,
the phrase "to the knowledge of the Company" or any similar phrase means the
actual (and not the constructive or imputed) knowledge after due inquiry of
Christopher P. Torto, Osvaldo deFaria, Glenn R. Friedly and James Militello.

                    REPRESENTATIONS AND WARRANTIES OF PARENT

     Except as set forth in the disclosure letter delivered at or prior to the
execution hereof to the Company, which shall refer to the relevant Sections of
this Agreement

                                      A-35
<PAGE>   365

(the "Parent Disclosure Schedule"), each of Parent and MergerCo represents and
warrants to the Company as follows:

     6.1 Existence; Good Standing; Authority; Compliance With Law.

     (a) Each of Parent and MergerCo is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation. Except as set forth in Section 6.1 of Parent Disclosure Schedule,
each of Parent and MergerCo is duly licensed or qualified to do business as a
foreign corporation and is in good standing under the laws of any other state of
the United States in which the character of the properties owned, leased or
operated by it therein or in which the transaction of its business makes such
qualification or licensing necessary, except where the failure to be so licensed
or qualified would not, individually or in the aggregate, reasonably be expected
to have a material adverse effect on the business, assets, properties, results
of operations or financial condition of Parent and the Parent Subsidiaries (as
defined herein) taken as a whole (a "Parent Material Adverse Effect"). Each of
Parent and MergerCo has all requisite corporate power and authority to own,
operate, lease and encumber its properties and carry on its business as now
conducted.

     (b) Each of the Parent Subsidiaries is a corporation, partnership or
limited liability company (or similar entity or association in the case of those
Parent Subsidiaries organized and existing other than under the laws of a state
of the United States) duly incorporated or organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation or
organization, has the corporate or other power and authority to own its
properties and to carry on its business as it is now being conducted, and is
duly qualified or licensed to do business and is in good standing in each
jurisdiction in which character of the properties owned, leased or operated by
it therein or in which the transaction of its business makes such qualification
or licensing necessary, except for jurisdictions in which such failures to be so
qualified or to be in good standing would not, individually or in the aggregate,
reasonably be expected to have a Parent Material Adverse Effect.

     (c) Except as set forth in Section 6.1(c) of the Parent Disclosure
Schedule, neither Parent, MergerCo nor any of the Parent Subsidiaries is in
violation of any order of any court, Governmental Entity or arbitration board or
tribunal, or any Law, applicable to Parent, MergerCo or any Parent Subsidiary or
by which any of their respective properties or assets is bound or affected by
which violation would, individually or in the aggregate, reasonably be expected
to have a Parent Material Adverse Effect. Parent, MergerCo and the Parent
Subsidiaries have obtained all franchises, grants, authorizations, licenses,
permits, easements, variances, exceptions, consents, waivers, rights,
certificates, approvals and orders of, and registrations required to be made
with any Governmental Entity that are material to its business as it is now
being or is intended to be conducted (the "Parent Permits"), where the failure
to obtain any such Parent Permits would not, individually or in the aggregate,
reasonably be expected to have a Parent Material Adverse Effect.

     (d) The copies of the Parent's Memorandum of Association ("Parent
Certificate") and by-laws ("Parent ByLaws"), each as amended through the date of
this Agreement
                                      A-36

that are incorporated by reference in, as exhibits to the Parent's Quarterly

by-laws.

     6.2 Authorization, Validity and Effect of Agreements.   Each of Parent and
MergerCo has the requisite power and authority to enter into the Transactions
and to execute and deliver this Agreement. The Parent Board has unanimously
approved this Agreement, the Merger and the other Transactions and has resolved
to recommend that the holders of Parent Common Stock adopt and approve this
Agreement at the stockholders' meeting of Parent to be held in accordance with
the provisions of Section 8.1. The Board of Directors of MergerCo (the "MergerCo
Board") and the stockholders of MergerCo have approved this Agreement and the
Transactions. Subject only to the approval of this Agreement by the holders of a
majority of the outstanding shares of Parent Common Stock (the "Requisite Parent
Vote"), the execution by Parent of this Agreement and the consummation of the
Transactions have been duly authorized by all requisite corporate action on the
part of Parent and MergerCo and no other corporate proceedings on the part of
Parent or MergerCo are necessary to authorize this Agreement or to consummate
the Transactions. As of the date hereof, all of the directors and executive
officers of Parent have indicated that they presently intend to vote all shares
of Parent Common Stock which they own to approve this Agreement and the
Transactions at the stockholders' meeting of Parent to be held in accordance
with the provisions of Section 8.1. This Agreement, assuming due and valid

shares of capital stock or other voting securities or options in respect thereof
have been issued except upon the exercise of the Parent Options outstanding on

which 1,500 shares were outstanding as of the date of this Agreement. All such

matter. Except as set forth in the Parent SEC Reports and in Section 6.3 of the
Parent Disclosure Schedule, there are no existing options, warrants, calls,
subscriptions, convertible securities, redemption rights or other rights,
agreements or commitments to which Parent is a party or by which Parent is bound

obligate Parent to issue, transfer or sell any shares of capital stock of
Parent, other than the Parent Options. Except as set forth in Section 6.3 of
Parent Disclosure Schedule or in the Parent SEC Reports, there are no agreements
or understandings to which Parent or any Parent Subsidiary is a party with
respect to the voting of any shares of capital stock of Parent or which restrict
the transfer of any such shares, nor does Parent have knowledge of any third
party agreements or understandings with respect to the voting of any such shares
or which restrict the transfer of any such shares. Except as set forth in
Section 6.3 of Parent Disclosure Schedule or in the Parent SEC Reports, there
are no outstanding contractual obligations of Parent or any Parent Subsidiary to
repurchase, redeem or otherwise acquire any shares of capital stock, partnership
interests or any other securities of Parent or any Parent Subsidiary. Except as
set forth in Section 6.3 of Parent Disclosure Schedule or in the Parent SEC

     6.6 No Violation; Consents.

     (a) Except as set forth in Section 6.6(a) of Parent Disclosure Schedule,
neither the execution and delivery by Parent of this Agreement nor consummation
by Parent of the Transactions in accordance with the terms hereof, will conflict
with or result in a breach of any provisions of Parent Certificate or Parent
ByLaws or any comparable organizational documents of any Parent Subsidiary.
Except as set forth in Section 6.6(a) of Parent Disclosure Schedule, the
execution and delivery by Parent of this Agreement and consummation by Parent of
the Transactions in accordance with the terms hereof will not violate, or
conflict with, or result in (x) a violation of any Law applicable to Parent or
any Parent Subsidiary or by which any property or asset of Parent or any Parent
Subsidiary is bound or affected or (y) any provision of, or constitute a default
(or an event which, with notice or lapse of time or both, would constitute a
default) under, or result in the termination or in a right of termination or
cancellation of, or accelerate the performance required by, or result in the
creation of any Lien upon any of the properties or assets of Parent or the
Parent Subsidiaries under, or result in being declared void, voidable or without
further binding effect, any of the terms, conditions or provisions of any
Contract to which Parent or any of Parent Subsidiaries is a party, or by which
Parent or any of the Parent Subsidiaries or any of their properties is bound,
except as would not, individually or in the aggregate, reasonably be expected to
have a Parent Material Adverse Effect. Other than the Regulatory Filings, the
execution and delivery of this Agreement by Parent does not, and the performance
of this Agreement by Parent and consummation of the Transactions does not,
require any consent, approval or authorization of, or declaration, filing or
registration with, any Governmental Entity, except where the failure to obtain
any such consent, approval or authorization of, or declaration, filing or
registration with, any governmental or regulatory authority would not,
individually or in the aggregate, reasonably be expected to have a Parent
Material Adverse Effect.

     (b) Section 6.6(b) of the Parent Disclosure Letter sets forth a correct and
complete list of all material Contracts to which Parent or any Parent
Subsidiaries are a party or by which they or their assets or properties is or
may be bound or affected under which consents or waivers are required prior to
consummation of the transactions contemplated by this Agreement and the
Transactions.

     6.7 SEC Documents.   Parent has filed all required forms, reports,
exhibits, schedules, statements and other documents with the SEC since September
2, 1998 (collectively, the "Parent SEC Reports"), all of which were prepared in
accordance with the applicable requirements of the Securities Laws. All required
Parent SEC Reports have been filed with the SEC and constitute all forms,
reports, exhibits, schedules, statements and other documents required to be
filed by Parent under the Securities Laws since September 2, 1998. As of their
respective dates, Parent SEC Reports, including any financial statement or
schedules included or incorporated therein by reference (i) complied as to form
in all material respects with the applicable requirements of the Securities Laws
and (ii) did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements

                                      A-39
<PAGE>   369

made therein, in the light of the circumstances under which they were made, not
misleading. Each of the consolidated balance sheets of Parent included in or
incorporated by reference into Parent SEC Reports (including the related notes
and schedules) fairly presents the consolidated results of operations and cash
flow position of Parent and Parent Subsidiaries as of its date and each of the
consolidated statements of income, retained earnings and cash flows of Parent
included in or incorporated by reference into Parent SEC Reports (including any
related notes and schedules) fairly presents the results of operations, retained
earnings or cash flows, as the case may be, of Parent and Parent Subsidiaries
for the periods set forth therein (subject, in the case of unaudited statements,
to normal year-end audit adjustments which would not be material in amount or
effect), in each case in accordance with generally accepted accounting
principles consistently applied during the periods involved, except as may be
noted therein and except, in the case of the unaudited statements, as permitted
by Form 10-Q pursuant to Section 13 or 15(d) of the Exchange Act. All of such
balance sheets and statements complied as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto. No Parent Subsidiary is subject to the periodic
reporting requirements of the Exchange Act or is otherwise required to file any
documents with the SEC or any national securities exchange or quotation service
or comparable Governmental Entity.

     6.8 Litigation.   Except as set forth in Section 6.8 of Parent Disclosure
Schedule and in the Parent SEC Reports, there is no litigation, suit, claim,
action or proceeding pending or, to the knowledge of Parent, threatened against
Parent or any of Parent Subsidiaries, as to which there is a reasonable
likelihood of an adverse determination and which, if adversely determined,
would, individually or in the aggregate, reasonably be expected to have a Parent
Material Adverse Effect. Neither Parent nor any Parent Subsidiary is subject to
any outstanding order, writ, injunction or decree which, individually or in the
aggregate, has resulted or would, individually or in the aggregate, reasonably
be expected to have a Parent Material Adverse Effect.

     6.9 Absence of Certain Changes.   Except as disclosed in Parent SEC Reports
filed with the SEC between September 30, 1999 and the date of this Agreement or

         (b) any Commitment entered into by Parent or any of Parent Subsidiaries
     outside the ordinary course of business except for Commitments for expenses
     of attorneys, accountants and investment bankers incurred in connection
     with the Transactions;

         (c) any material change in Parent's accounting principles, practices or
     methods; or

                                      A-40
<PAGE>   370

         (d) any damage, destruction or other casualty loss with respect to any
     asset or property owned, leased or otherwise used by it or any Parent
     Subsidiaries, whether or not covered by insurance, which damage,
     destruction or loss, individually or in the aggregate, has resulted or
     would, individually or in the aggregate, reasonably be expected to have a
     Parent Material Adverse Effect.

     6.10 Intellectual Property.   Parent or the Parent Subsidiaries are the
owner free and clear of any Liens of, or a licensee under a valid unrestricted
license for, all Intellectual Property which are material to the business of
Parent and the Parent Subsidiaries as currently conducted, taken as a whole.
Except as disclosed in Parent SEC Reports or Section 6.10 of Parent Disclosure
Schedule, there are no claims pending or, to Parent's knowledge, threatened,
that Parent or any Parent Subsidiary is in violation of any such intellectual
property right of any third party or that challenges the validity,
enforceability, ownership, or right to use, sell, or license any Intellectual
Property which would, individually or in the aggregate, reasonably be expected
to have a Parent Material Adverse Effect, and, to Parent's knowledge, no third
party is in violation of any intellectual property rights of Parent or any
Parent Subsidiary which would, individually or in the aggregate, reasonably be
expected to have a Parent Material Adverse Effect.

     6.11 No Brokers.   Neither Parent nor any of Parent Subsidiaries has
entered into any contract, arrangement or understanding with any person or firm
which may result in the obligation of such entity or the Company to pay any
finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or consummation of
the Transactions, except that Parent has retained Goldman, Sachs & Co. and
Albert Schneider as its financial advisor in connection with the Transactions.
Other than the foregoing arrangements and the Company's arrangements with Morgan
Stanley, Parent is not aware of any claim for payment of any finder's fees,
brokerage or agent's commissions or other like payments in connection with the
negotiations leading to this Agreement or consummation of the Transactions.

     6.12 Opinion of Financial Advisor.   Parent has received the opinion of
Goldman, Sachs & Co. to the effect that, as of the date hereof, the Merger
Consideration is fair to the holders of Parent Common Stock from a financial
point of view.

     6.13 Taxes.   Except as set forth in Section 6.13 of the Parent Disclosure
Schedule, each of the Parent and the Parent Subsidiaries (i) has filed, or will
have filed, all Tax Returns required to be filed by it on or before the Closing
Date (taking into account any applicable extensions) and all such Tax Returns
are true, correct and complete in all material respects, and (ii) has paid, or
will have paid, all Taxes required to be paid by it on or before the Closing
Date (whether or not shown on any Tax Return), except, in each case, where the
failure to file such Tax Returns or pay such Taxes would not, individually or in
the aggregate, reasonably be expected to have a Parent Material Adverse Effect.
Except as set forth in Section 6.13 of the Parent Disclosure Schedule, the most
recent unaudited financial statements contained in the Parent's Quarterly Report
on Form 10-Q for the quarter ended September 30, 1999 reflect an adequate
reserve for all material Taxes payable by the Parent and the Parent Subsidiaries
for all taxable periods and portions thereof through the date of such financial
statements in

                                      A-41
<PAGE>   371

accordance with United States GAAP. To the knowledge of the Parent, and except
as set forth in Section 6.13 of the Parent Disclosure Schedule, no deficiencies
for any Taxes have been proposed, asserted or assessed against the Parent or any
of the Parent Subsidiaries, there are no Tax liens on any assets of the Parent
or of any of the Parent Subsidiaries (other than liens for current Taxes not yet
due), and no requests for waivers of the time to assess any such Taxes are
pending. The transactions described in Section 8.11, including the
Reincorporation (as defined herein), will not result in any material Tax
liability to Parent or to ATX.

     6.14 Employee Benefit Plans.   Each Parent Benefit Plan which is intended
to be qualified under Section 401(a) of the Code has received a favorable
determination or approval letter from the IRS regarding its qualification under
such section, and neither the Parent nor any Affiliate knows of any event that
has occurred which would preclude qualified status. With respect each Parent
Benefit Plan, there has been no material failure to comply with any applicable
provision of ERISA, the Code or any other law which would subject the Parent or
any Affiliate to liability for any damages, penalty, or taxes that would,
individually or in the aggregate, reasonably be expected to have a Parent
Material Adverse Effect.

     6.15 Definition of Parent's Knowledge.   As used in this Agreement, the
phrase "to the knowledge of Parent" or any similar phrase means the actual (and
not the constructive or imputed) knowledge after due inquiry of the executive
officers of Parent.

                                  ARTICLE VII

                                   COVENANTS

     7.1 No Solicitations.

     (a) The Company represents and warrants that it has terminated, and has
caused its subsidiaries and affiliates, and their respective officers,
directors, employees, investment bankers, attorneys, accountants and other
advisors or representatives to terminate, any activities, discussions or
negotiations relating to, or that may be reasonably be expected to lead to, any
Acquisition Proposal (as hereinafter defined) and will promptly request the
return of all confidential information regarding the Company provided to any
third party prior to the date of this Agreement pursuant to the terms of any
confidentiality agreements. From the date hereof until the termination hereof
and except as permitted by the following provisions of this Section 7.1, the
Company shall not, and shall not authorize or permit any of its officers,
directors or employees or any investment banker, financial advisor, attorney,
accountant or other advisor or Representative retained by it to, directly or
indirectly, (i) solicit, initiate or encourage (including by way of furnishing
non-public information), or take any other action to facilitate, any inquiries
or the making of any proposal that constitutes an Acquisition Proposal or any
inquiries or making of any proposal that constitutes, or may reasonably be
expected to lead to, an Acquisition Proposal, or (ii) participate in any
activities, discussions or negotiations regarding an Acquisition Proposal;
provided, however, that subject to compliance by the Company with the provisions
of Section 7.1(b), the Company Board

                                      A-42
<PAGE>   372

may furnish information to, or enter into discussions or negotiations with, any
person that makes an unsolicited written Acquisition Proposal if, and only to
the extent that (A) the Company Board, after consultation with its outside legal
counsel, determines in good faith that such action is necessary for the Company
Board to comply with its fiduciary duties to the Company's stockholders under
applicable law, (B) such Acquisition Proposal is not subject to any financing
contingencies or is, in the good faith judgment of the Company Board after
consultation with a nationally recognized financial advisor, reasonably capable
of being financed, and is at least as likely to be consummated as is the Merger,
(C) the Company Board determines in good faith that such Acquisition Proposal,
based upon such matters as it deems relevant (including consultation with a
nationally recognized financial advisor) would, if consummated, result in a
transaction more favorable to the Company's stockholders from a financial point
of view than the Merger (any such more favorable Acquisition Proposal being
referred to herein as a "Superior Proposal"), (D) the Company receives from such
person an executed confidentiality agreement in reasonably customary form and
(E) at least three (3) business days prior to taking such action, the Company
shall provide written notice to Parent to the effect that it is taking such
action.

     (b) Prior to providing any information to or entering into discussions with
any person in connection with an Acquisition Proposal by a person as set forth
in Section 7.1(a), the Company shall notify Parent orally and in writing of any
Acquisition Proposal (including, without limitation, the material terms and
conditions thereof and the identity of the person making it) or any inquiries
indicating that any person is considering making or wishes to make an
Acquisition Proposal, as promptly as practicable (but in no case later than 24
hours) after its receipt thereof, and shall provide Parent with a copy of any
written Acquisition Proposal or amendments or supplements thereto, and shall
thereafter inform Parent on a prompt basis of (x) any material changes to the
terms and conditions of such Acquisition Proposal, and shall promptly give
Parent a copy of any information delivered to such person that amends or
supplements the Acquisition Proposal and that has not previously been provided
to Parent, and (y) any request by any person for nonpublic information relating
to its or any Company Subsidiaries' properties, books or records.

     (c) The Company Board will not withdraw or modify, or propose to withdraw
or modify, in any manner adverse to Parent, its approval or recommendation of
this Agreement or the Merger except in connection with a Superior Proposal and
then only upon or after the termination of this Agreement pursuant to Section
10.1(c) and payment to Parent of the amounts referred to in Section 10.2(b).

     (d) Nothing contained in this Section 7.1 shall prohibit the Company from
at any time taking and disclosing to its stockholders a position contemplated by
Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or making any
disclosure required by Rule 14a-9 promulgated under the Exchange Act if, the
Company Board determines, in its good faith reasonable judgment after
consultation with outside legal counsel, that failure to so disclose would be
inconsistent with its obligations under applicable law.

                                      A-43
<PAGE>   373

     (e) As used in this Agreement, the term "Acquisition Proposal" shall mean
any proposed or actual (i) merger, consolidation or similar transaction
involving the Company, (ii) sale, lease, exchange, mortgage, pledge, transfer or
other disposition, directly or indirectly, by merger, consolidation, share
exchange or otherwise, of any assets of the Company or the Company Subsidiaries
representing 15% or more of the consolidated assets of the Company and the
Company Subsidiaries, (iii) issue, sale or other disposition by the Company of

securities convertible into, such securities) representing 15% or more of the
votes associated with the outstanding securities of the Company, (iv) tender
offer or exchange offer in which any person shall acquire beneficial ownership
(as such term is defined in Rule 13d-3 under the Exchange Act), or the right to
acquire beneficial ownership, or any "group" (as such term is defined under the
Exchange Act) shall have been formed which beneficially owns or has the right to
acquire beneficial ownership of, 15% or more of the outstanding shares of
Company Common Stock, (v) recapitalization, restructuring, liquidation,
dissolution, or other similar type of transaction with respect to the Company,
(vi) transaction which is similar in form, substance or purpose to any of the
foregoing transactions or (vii) any public announcement of a proposal or plan to
do any of the foregoing (including, without limitation, the filing of a
registration statement under the Securities Act) or any agreement to engage in
any of the foregoing; provided, however, that the term "Acquisition Proposal"
shall not include the Merger and the other Transactions.

     7.2 Conduct of Businesses.

     (a) Conduct by the Company.   Prior to the Effective Time, except as
specifically permitted by this Agreement, unless Parent or MergerCo has
consented in writing thereto, the Company shall cause each Company Subsidiary to
conduct its operations according to their usual, regular and ordinary course of
business consistent with past practice or in accordance with the Business Plan
of the Company which has been provided to Parent ("Business Plan") and, to the
extent consistent therewith, with no less diligence and effort then would be
applied in the absence of this Agreement, will use its reasonable best efforts
to, and to cause each Company Subsidiary to, preserve intact the business
organization of the Company and each of the Company Subsidiaries, to keep
available the services of the present officers and key employees of the Company
and the Company Subsidiaries, and to preserve the good will of customers,
suppliers and all other persons having business relationships with the Company
and the Company Subsidiaries. Without limiting the generality of the foregoing,
and except as set forth on Section 7.2(a) of the Company Disclosure Schedule,
neither the Company nor any Company Subsidiary shall (except as expressly
permitted by this Agreement or to the extent Parent or MergerCo shall otherwise
consent in writing):

         (i) directly or indirectly, split, combine, subdivide, reclassify or
     redeem, retire, purchase or otherwise acquire, or propose to redeem, retire
     or purchase or otherwise acquire, any shares of its capital stock, or any
     of its other securities; or declare, set aside or pay any dividend or other
     distribution (whether in cash, stock or property

                                      A-44
<PAGE>   374

     rights to purchase or otherwise) any stock of any class or any other
     securities (including indebtedness having the right to vote) or equity
     equivalents (including, without limitation, securities convertible into
     capital stock, options, warrants and stock appreciation rights), other than
     the issuance of shares of Company Common Stock upon the exercise of Company
     Options in accordance with their present terms;

         (iii) acquire, sell, lease, encumber, license, pledge, grant, transfer
     or dispose of any assets outside the ordinary course of business which are
     material to the Company or any of the Company Subsidiaries (whether by
     merger, consolidation, purchase, sale, asset acquisition, stock acquisition
     or otherwise) or enter into any material commitment or transaction outside
     the ordinary course of business, except as set forth in Section 7.2(a) of
     the Company Disclosure Schedule;

         (iv) except as contemplated by the Business Plan, incur, assume or

     for, whether directly, contingently or otherwise) any debt of others, make
     any loans, advances or capital contributions, or investments in, mortgage,
     pledge or otherwise encumber any material assets, create or suffer any
     material Lien thereupon other than in the ordinary course of business
     consistent with prior practice;

         (v) pay, discharge or satisfy any claims, liabilities or obligations
     (absolute, accrued, asserted or unasserted, contingent or otherwise), other

     business consistent with past practice, or (B) in connection with the
     transactions contemplated by this Agreement;

     business consistent with past practice, increase in any manner the

     effect as of the date hereof, (D) pay any benefit not required by any
     existing plan or arrangement (including the granting of stock options,

                                      A-45
<PAGE>   375

     shares of restricted stock or performance units) or grant any severance or
     termination pay to (except pursuant to existing agreements, plans or
     policies), or enter into any employment or severance agreement with, any
     director, officer or other employee of the Company or any Company
     Subsidiaries or (E) establish, adopt, enter into, amend or take any action
     to accelerate rights under any collective bargaining, bonus, profit

     termination, severance or other employee benefit plan, agreement, trust,
     fund, policy or arrangement for the benefit or welfare of any directors,
     officers or current or former employees, except in each case to the extent

     Agreement will be deemed to prohibit the payment of benefits as they become

     Bylaws or comparable organizational documents of any Company Subsidiary,
     except as expressly provided by the terms of this Agreement;

     Company or any of its Subsidiaries;

         (x) terminate, cancel or request any material change in, or agree to

     would be material to the Company and the Company Subsidiaries taken as a
     whole, in either case other than in the ordinary course of business
     consistent with past practice;

         (xi) make or authorize any capital expenditure, which would be material
     to the Company and the Company Subsidiaries taken as a whole, other than in
     the ordinary course of business consistent with past practice or in
     accordance with the Business Plan;

         (xii) enter into any agreement or arrangement that materially limits or
     otherwise restricts the Company or any Company Subsidiary or any successor
     thereto, or that would, after the Effective Time, limit or restrict the
     Surviving Corporation and its affiliates (including Parent) or any
     successor thereto, from engaging or competing in any line of business or in
     any geographic area, other than in the ordinary course of business
     consistent with past practice;

         (xiii) adopt a plan of complete or partial liquidation or resolutions
     providing for or authorizing such a liquidation or a dissolution, merger,
     consolidation, restructuring, recapitalization or reorganization (other
     than plans of complete or partial liquidation or dissolution of inactive
     Company Subsidiaries);

         (xiv) settle, waive, release, assign or compromise any material rights,
     claims or litigation (whether or not commenced prior to the date of this
     Agreement);

         (xv) take any action that would result in any of its representations or
     warranties set forth in this Agreement becoming untrue or cause any
     conditions to closing set forth in Article IX, to not be satisfied, other
     than those actions that

                                      A-46
<PAGE>   376

     would not materially adversely affect the Company's ability to consummate
     the transactions contemplated by this Agreement; or

         (xvi) authorize or enter into any formal or informal written or other
     agreement or otherwise make any commitment to do any of the foregoing
     actions.

     (b) Conduct by Parent.   Except as expressly provided in this Agreement or
as disclosed on Section 7.2(b) of Parent Disclosure Schedule, neither Parent nor
any Parent Subsidiary shall (except as expressly permitted by this Agreement or
to the extent the Company shall otherwise consent in writing):

         (i) declare, set aside or pay any dividend or other distribution
     (whether in cash, stock or property or any combination thereof) in respect
     of Parent Common Stock, except for dividends paid by any Parent Subsidiary
     to Parent or any Parent Subsidiary that is, directly or indirectly, wholly
     owned by Parent; or

         (ii) authorize or enter into any formal or informal written or other
     agreement or otherwise make any commitment to do any of the foregoing
     actions; provided that nothing in this Section 7.2(b) shall prohibit Parent
     from undertaking any actions contemplated by the definition of Base
     Adjustments in Section 3.1(c)(ii) prior to Closing.

     7.3 Tax-Free Treatment.   Parent, MergerCo and the Company intend that the
Merger will qualify as either (i) a reorganization within the meaning of Section
368(a) of the Code or (ii) a transaction that, together with the Reincorporation
(as defined herein) qualifies as an exchange under the provisions of Section 351
of the Code and which is treated for U.S. federal income tax purposes as a
transfer of Company Common Stock by the shareholders of the Company to Parent in
exchange for the Merger Consideration. None of Parent, MergerCo or the Company
shall take, or fail to take, or cause to be taken or fail to cause to be taken,
any action, whether before or after the Closing, which action or failure to take
any action would cause the Merger to fail to constitute a "reorganization"
within the meaning of Section 368(a) of the Code or a transaction that, together
with the Reincorporation (as defined herein) qualifies as an exchange under the
provisions of Section 351 of the Code and which is treated for U.S. federal
income tax purposes as a transfer of Company Common Stock by the shareholders of
the Company to Parent in exchange for the Merger Consideration. However, it is
further intended by all of the parties hereto that if the transactions with ATX
described in Section 8.11 occur, and this Agreement is assigned as provided in
Section 11.5, then the incorporation of ATX, the transactions with ATX described
in Section 8.11, and the transactions described in this Agreement will be
treated for U.S. federal income tax purposes as one integrated transaction
qualifying as an exchange under the provisions of Section 351 of the Code in
which the shareholders of the Company transfer Company Common Stock in exchange
for ATX stock. No party to this Agreement shall take a position on any Tax
return that is inconsistent with the intentions expressed in this Section 7.3.

                             ADDITIONAL AGREEMENTS

     8.1 Meetings of Stockholders.   Following execution of this Agreement, (i)
Parent will take all action necessary in accordance with applicable law, Parent
Certificate and Parent ByLaws to convene a meeting of its stockholders as
promptly as practicable to consider and vote upon the approval of the issuance
of Parent Common Stock to be issued pursuant to the Merger and (ii) the Company
will take all action necessary in accordance with applicable Law, the Company
Certificate and the Company Bylaws to convene a meeting of its stockholders as
promptly as practicable to consider and vote upon the approval of this Agreement
and the Transactions (the "Company Stockholders Meeting"). The proxy statements
of Parent and the Company related to their respective stockholders' meeting
shall, subject to Section 7.1 hereof, contain the recommendation of Parent Board
and the Company Board, respectively, that its stockholders approve this
Agreement and the Transactions. Subject to and in accordance with applicable
Law, each of Parent and the Company shall use its reasonable best efforts to
obtain the such approval, including, without limitation, by timely mailing the
Proxy Statement (as hereinafter defined) contained in the Form S-4 to its
stockholders. Parent and the Company shall coordinate and cooperate with each
other with respect to the timing of their respective stockholders' meetings and
shall use their reasonable best efforts to hold such meetings on the same day.

     8.2 HSR and Other Filings.

     (a) Subject to the terms and conditions herein provided and to applicable
legal requirements, each of the parties hereto agrees to use its reasonable best
efforts to (i) take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable to consummate and make effective
as promptly as practicable the transactions contemplated by this Agreement and
(ii) to cooperate with each other in connection with the foregoing, including
the taking of such actions as are necessary to obtain any necessary consents,
licenses, approvals, orders, exemptions and authorizations by or from any public
or private third party or Governmental Entity, including, without limitation,
those consents, licenses, approvals, exemptions or authorizations required with
respect to the agreements set forth in Sections 5.6(a) and 5.6(b) of the Company
Disclosure Schedule and any others that are required to be obtained under any
Law or any Contract to which the Company or any Company Subsidiary is a party or
by which any of their respective properties or assets are bound, (iii) to defend
all lawsuits or other legal proceedings challenging this Agreement or the
consummation of the Transactions, (iv) to cause to be lifted or rescinded any
injunction or restraining order or other order adversely affecting the ability
of the parties to consummate the Transactions, and (iv) to effect all necessary
registrations and submissions of information requested by governmental
authorities. For purposes of the foregoing sentence, the obligations of Parent
and the Company to use their "reasonable best efforts" to obtain waivers,
consents and approvals to loan agreements, leases and other contracts shall not
include any obligation to agree to an adverse modification of the terms of such
documents or to prepay or incur additional obligations to such other parties.
If, at any

                                      A-48
<PAGE>   378

time after the Effective Time, any further action is necessary or desirable to
carry out the purpose of this Agreement, the proper officers and directors of
Parent and the Company shall take all such necessary action. The Company shall
use its reasonable best efforts to properly record all assignments of its
Intellectual Property and make all other necessary filings with the United
States Patent and Trademark Office and the United States Copyright Office.

     (b) Without limiting the generality of the foregoing, as promptly as
practicable, Parent and the Company each shall properly prepare and file any
other filings required under applicable Law relating to the Merger and the other
Transactions (including filings, if any, required under the HSR Act, the
Securities Act, the Exchange Act and any other applicable federal or Blue Sky
Laws, the DGCL, Bermuda Law, other applicable Law and the rules and regulations
of NASDAQ, and the Communications Act, the PUC Regulations, and the Utility Laws
(collectively, "Other Filings"). Each of Parent and the Company shall promptly
notify the other of the receipt of any comments on, or any request for
amendments or supplements to, any Other Filings by any Governmental Entity or
official, and each of Parent and the Company shall supply the other with copies
of all correspondence between it and each of its Subsidiaries and
representatives, on the one hand, and any other appropriate governmental
official, on the other hand, with respect to any Other Filings. None of the
parties will file any such document if any of the other parties shall have
reasonably objected to the filing of such document. No party to this Agreement
shall consent to any voluntary extension of any statutory deadline or waiting
period or to any voluntary delay of the consummation of the Merger and the other
Transactions at the behest of any Governmental Entity without the consent and
agreement of the other party to this Agreement, which consent shall not be
unreasonably withheld or delayed. Parent and the Company hereby covenant and
agree to use their respective reasonable best efforts to secure termination of
any waiting periods under the HSR Act and obtain the approval of the Federal
Trade Commission (the "FTC") or any other Governmental Entity for the
transactions contemplated hereby. The Company and Parent shall keep the other
apprised of the status of matters relating to the completion of the transactions
contemplated hereby and work cooperatively in connection with obtaining any
consents from Governmental Entity, including, without limitation: (i) promptly
notifying the other of, and if in writing, furnishing the other with copies of
(or, in the case of material oral communications, advise the other orally of)
any communications from or with any Governmental Entity with respect to the
Merger or any of the other transactions contemplated by this Agreement, (ii)
permitting the other party to review and discuss in advance, and considering in
good faith the views of one another in connection with, any proposed written (or
any material proposed oral) communication with any Governmental Entity, (iii)
not participating in any meeting with any Governmental Entity unless it consults
with the other party in advance and to the extent permitted by such Governmental
Entity gives the other party the opportunity to attend and participate thereat,
(iv) furnishing the other party with copies of all correspondence, filings and
communications (and memoranda setting forth the substance thereof) between it
and any Governmental Entity with respect to this Agreement and the Merger, and
(v) furnishing the other party with such necessary information and

                                      A-49
<PAGE>   379

reasonable assistance as such other party may reasonably request in connection
with its preparation of necessary filings or submissions of information to any
Governmental Entity. The Company and Parent may, as each deems advisable and
necessary, reasonably designate any competitively sensitive material provided to
the other under this Section as "outside counsel only." Such materials and the
information contained therein shall be given only to the outside legal counsel
of the recipient and will not be disclosed by such outside counsel to employees,
officers, or directors of the recipient unless express permission is obtained in
advance from the source of the materials (the Company or Parent, as the case may
be) or its legal counsel.

     8.3 Proxy Statement; Registration Statement.   As promptly as practicable
after the execution of this Agreement, Parent and the Company shall prepare and
file with the SEC under the Securities Act a registration statement on Form S-4
(such registration statement, together with any amendments or supplements
thereto, the "Form S-4"), in connection with the registration under the
Securities Act of the shares of Parent Common Stock to be distributed to the
stockholders of the Company in the Merger (the "Registered Securities"). The
Form S-4 also shall include a joint proxy statement/prospectus and forms of
proxies (such joint proxy statement/prospectus together with any amendments or
supplements thereto, the "Proxy Statement") relating to the stockholder meetings
of Parent and the Company and the vote of the stockholders of Parent and the
Company with respect to this Agreement and the Transactions. Parent will cause
the Proxy Statement and the Form S-4 to comply as to form in all material
respects with the applicable provisions of the Securities Act, the Exchange Act
and the rules and regulations thereunder, the rules and regulations of NASDAQ,
and the DGCL and Bermuda Law, and the Company will cause the Proxy Statement to
comply as to form in all material respects with the applicable provisions of the
Exchange Act and the rules and regulations thereunder, the rules and regulations
of NASDAQ and the DGCL. Each of Parent and the Company shall furnish all
information about itself and its business and operations and all necessary
financial information to the other as the other may reasonably request in
connection with the preparation of the Proxy Statement and the Form S-4. Parent
shall use its reasonable best efforts, and the Company will cooperate with them,
to have the Form S-4 declared effective by the SEC as promptly as practicable
(including clearing the Proxy Statement with the SEC). Each of Parent and the
Company agrees promptly to correct any information provided by it for use in the
Proxy Statement and the Form S-4 if and to the extent that such information
shall have become false or misleading in any material respect, and each of the
parties hereto further agrees to take all steps necessary to amend or supplement
the Proxy Statement and, in the case of Parent, the Form S-4, and to cause the
Proxy Statement and, in the case of Parent, the Form S-4, as so amended or
supplemented to be filed with the SEC and to be disseminated to their respective
stockholders, in each case as and to the extent required by applicable federal
and state securities laws. No amendment or supplement to the Proxy Statement
will be made without the approval of each of Parent and the Company, which
approval shall not be unreasonably withheld or delayed. Each of Parent and the
Company agrees that the information provided by it for inclusion in the Proxy
Statement or the Form S-4 and each amendment or supplement thereto, at the time
of

                                      A-50
<PAGE>   380

mailing thereof and at the time of the respective meetings of stockholders of
Parent and the Company, will not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. Each of the Company and Parent will advise the other, and
deliver copies (if any) to the other, promptly after either receives notice
thereof, of any request by the SEC for amendment of the Proxy Statement or the
Form S-4 or comments thereon and responses thereto or requests by the SEC for
additional information, or notice of the time when the Form S-4 has become
effective or any supplement or amendment has been filed, the issuance of any
stop order or the suspension of the qualification of the Registered Securities
issuable in connection with the Merger for offering or sale in any jurisdiction.
Each of Parent and the Company shall use its reasonable best efforts to timely
mail the Proxy Statement to its stockholders as promptly as practicable
following the effective date of the Proxy Statement.

     8.4 Listing Application.   Parent and the Company shall cooperate and
promptly prepare and submit to the NASDAQ all reports, applications and other
documents that may be necessary or desirable to enable all of the shares of
Parent Common Stock that will be outstanding or will be reserved for issuance at
the Effective Time to be listed for trading on the NASDAQ. Each of Parent and
the Company shall furnish all information about itself and its business and
operation and all necessary financial information to the other as the other may
reasonably request in connection with such NASDAQ listing process. Each of
Parent and the Company agrees promptly to correct any information provided by it
for use in the NASDAQ listing process if and to the extent that such information
shall have become false or misleading in any material respect. Each of Parent
and the Company will advise and deliver copies (if any) to the other party,
promptly after it receives notice thereof, of any request by the NASDAQ for
amendment of any submitted materials or comments thereon and responses thereto
or requests by the NASDAQ for additional information. The parties shall use
their reasonable best efforts to cause the Surviving Corporation to cause the
Company Common Stock to be de-listed from NASDAQ and de-registered under the
Exchange Act as soon as practicable following the Effective Time.

     8.5 Affiliates of the Company.

     (a) At least 30 days prior to the Closing Date, the Company shall deliver
to Parent a list of names and addresses of those persons who were, in the
Company's reasonable judgment, at the record date for its stockholders' meeting
to approve the Merger, "affiliates" (each such person, an "Affiliate") of the
Company within the meaning of Rule 145. The Company shall provide Parent such
information and documents as Parent shall reasonably request for purposes of
reviewing such list. The Company shall advise the persons identified on the list
of the resale restrictions imposed by applicable securities laws and shall use
its reasonable best efforts to deliver or cause to be delivered to Parent, prior
to the Closing Date, from each of the Affiliates of the Company identified in
the foregoing list, an Affiliate Letter in the form attached hereto as Exhibit
A. Parent shall be entitled to place legends as specified in such Affiliate
Letters

                                      A-51
<PAGE>   381

by such Affiliates pursuant to the terms of this Agreement, and to issue
appropriate stop transfer instructions to the transfer agent for such shares of
Parent Common Stock, consistent with the terms of such Affiliate Letters.

     (b) Parent shall file the reports required to be filed by it under the
Exchange Act and the rules and regulations adopted by the SEC thereunder, and it
will take such further action as any Affiliate of the Company may reasonably
request, all to the extent required from time to time to enable such Affiliate
to sell shares of Parent Common Stock received by such Affiliate in the Merger
without registration under the Securities Act pursuant to (i) Rule 145(d)(1) or
(ii) any successor rule or regulation hereafter adopted by the SEC.

     8.6 Expenses.   Except as otherwise provided in Section 10.2(b), whether or
not the Merger is consummated, all Expenses incurred in connection with this
Agreement and the Transactions shall be paid by the party incurring such
Expenses. For purposes of this Agreement, "Expenses" consist of all
out-of-pocket expenses (including, all fees and expenses of counsel,
accountants, investment bankers, experts and consultants to a party to this
Agreement and its affiliates) incurred by a party or on its behalf in connection
with or related to the authorization, preparation, negotiation, execution and
performance of this Agreement, the preparation, printing, filing and mailing of
the Proxy Statement, the solicitation of stockholder approvals and all other
matters related to the closing of the transactions contemplated by this
Agreement.

     8.7 Officers' and Directors' Indemnification.

     (a) In the event of any threatened or actual claim, action, proceeding or
investigation, whether civil, criminal or administrative, including, without
limitation, any such claim, action, suit, demand, proceeding or investigation in
which any person who is now, or has been at any time prior to the date hereof,
or who becomes prior to the Effective Time, a director, officer, employee,
fiduciary or agent of the Company or any of the Company Subsidiaries (the
"Indemnified Parties") is, or is threatened to be, made a party based in whole
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director, officer, employee, fiduciary or agent of the
Company or any of the Company Subsidiaries, or is or was serving at the request
of the Company or any of the Company Subsidiaries as a director, officer,
employee, fiduciary or agent of the Company or any Company Subsidiary or (ii)
the negotiation, execution or performance of this Agreement or any of the
Transactions, whether in any case asserted or arising before or after the
Effective Time, the parties hereto agree to cooperate and use their reasonable
best efforts to defend against and respond thereto. It is understood and agreed
that the Company shall indemnify and hold harmless, and after the Effective Time
the Surviving Corporation and Parent shall indemnify and hold harmless, as and
to the full extent permitted by applicable law, each Indemnified Party against
any losses, claims, damages, liabilities, costs, expenses (including attorneys'
fees and expenses), judgments, fines and amounts paid in settlement in
connection with any such threatened or actual claim, action, suit, demand,
proceeding or investigation. In the event any such Indemnified Party is or
becomes

                                      A-52
<PAGE>   382

involved in any capacity in any action, proceeding or investigation for which
indemnification is to be provided under this Agreement (whether asserted or
arising before or after the Effective Time), (A) the Company, and Parent and the
Surviving Corporation after the Effective Time, shall promptly pay expenses in
advance of the final disposition of any claim, action, suit, demand, proceeding
or investigation to the full extent permitted by law, provided that the
Indemnified Party may not retain more than one counsel (in addition to any
necessary local counsel) to represent all the Indemnified Parties and the
Company, Parent and the Surviving Corporation shall pay all reasonable fees and
expenses for such counsel for the Indemnified Parties promptly after statements
therefor are received and (B) the Company, Parent and the Surviving Corporation
will use their respective reasonable best efforts to assist in the defense of
any such matter; provided that in no event shall the Company, Parent or the
Surviving Corporation be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld); and provided
further that neither Parent nor the Surviving Corporation shall have no
obligation hereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall become
final and non-appealable, that indemnification of such Indemnified Party in the
manner contemplated hereby is prohibited by applicable law. Any Indemnified
Party wishing to claim indemnification under this Section 8.7, upon learning of
any such claim, action, suit, demand, proceeding or investigation, shall notify
the Company and, after the Effective Time, Parent and the Surviving Corporation,
thereof; provided that the failure to so notify shall not affect the obligations
of the Company, Parent and the Surviving Corporation except to the extent such
failure to notify materially prejudices such party.

     (b) Parent agrees that all rights to indemnification existing in favor of,
and all limitations on the personal liability of, the directors, officers,
employees and agents of the Company and the Company Subsidiaries provided for in
the Company Certificate or Bylaws as in effect as of the date hereof with
respect to matters occurring prior to the Effective Time, and including the
Merger, shall continue in full force and effect for a period of not less then
six years from the Effective Time; provided, however, that all rights to
indemnification in respect of any claims (each a "Claim") asserted or made
within such period shall continue until the final disposition of such Claim.
Prior to the Effective Time, the Company may purchase an extended reporting
period endorsement under the Company's existing directors' and officers'
liability insurance coverage for the Company's directors and officers in a form
and with terms acceptable to the Company, which shall provide such directors and
officers with coverage for six years following the Effective Time of not less
than the existing coverage under, and have other terms not materially less
favorable to, the insured persons than the directors' and officers' liability
insurance coverage presently maintained by the Company, so long as the cost is
less than $ 750,000, provided that, the Company agrees to cooperate in good
faith with the Parent in order to obtain the lowest premium for the above
referenced coverage. In the event that $ 750,000 is insufficient for the above
referenced coverage, the Company may spend up to that amount to purchase such
lesser coverage as is possible.

     (c) This Section 8.7 is intended for the irrevocable benefit of, and to
grant third party rights to, the Indemnified Parties and shall be binding on all
successors and assigns of Parent, the Company and the Surviving Corporation.
Each of the Indemnified Parties shall be entitled to enforce the covenants
contained in this Section 8.7.

     (d) In the event that Parent, the Surviving Corporation or any of its
successors or assigns (i) consolidates with or merges into any other person or
entity and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers or conveys all or substantially
all of its properties and assets to any person or entity, then, and in each such
case, proper provision shall be made so that the successors and assigns of
Parent or the Surviving Corporation assume the obligations set forth in this
Section 8.7.

     8.8 Access to Information; Confidentiality.   From the date hereof until
the Effective Time, each of Parent and the Company shall, and shall cause each
of their respective Subsidiaries and each of their and their respective

officers, accountants, consultants, legal counsel, financial advisors,
investment bankers, employees, agents and other representatives (collectively
"Representatives") of the other complete access at all reasonable times, upon
prior notice, to such Representatives, properties, books, records and contracts,
and shall furnish to the other such financial, operating and other data and
information concerning the business, properties, contracts, assets, liabilities,
personnel and other aspects of the other party and its Subsidiaries as the other
or its Representatives may reasonably request. Prior to the Effective Time, the
Company and the Parent shall hold in confidence all such information on the
terms and subject to the conditions contained in that certain confidentiality
agreement between Parent and the Company dated January 27, 2000 (the
"Confidentiality Agreement"). The Company hereby waives the provisions of the
Confidentiality Agreement as and to the extent necessary to permit the making
and consummation of the transactions contemplated by this Agreement. At the
Effective Time, such Confidentiality Agreement shall terminate.

     8.9 Publicity.   Parent and the Company shall consult with each other
before issuing any press release or otherwise making any public statements with
respect to this Agreement or any transaction contemplated hereby and shall not
issue any such press release or make any such public statement without the prior
consent of the other party, which consent shall not be unreasonably withheld;
provided, however, that a party may, without the prior consent of the other
party, issue such press release or make such public statement as may be required
by law or the applicable rules of any stock exchange if it has used its best
efforts to consult with the other party and to obtain such party's consent but
has been unable to do so in a timely manner. With regard to the Merger, the
parties shall make a joint public announcement of the Transactions no later than
(i) the close of trading on NASDAQ on the day this Agreement is signed, if such
signing occurs during a business day or (ii) the opening of trading on NASDAQ on
the business day following the date on which this Agreement is signed, if such
signing does not occur during a business day.

     (b) Parent agrees that individuals who are employed by the Company or any
Company Subsidiary immediately prior to the Closing Date shall remain employees

Plans (but not bonus or equity-based plans) on substantially similar terms to
those currently in effect. After the Effective Time, if Parent decides to move
the Affected Employees to a Parent employee benefit plan, the Affected Employees
will be permitted to participate in Parent employee benefit plan on terms
substantially similar to those provided to employees of Parent.

business days to such written notice, the Company shall not take any action
involving any Material Decision. "Material Decision" shall mean, for purposes of
this Agreement, any of the following to the extent the same may affect the

     expected to have, a material adverse effect on the business, properties,
     assets, results of operations or financial condition of the Company and the
     Company Subsidiaries taken as a whole (other than any (i) regulatory
     changes generally affecting the industries in which the Company operates,
     including changes due to actual or proposed changes in law or regulations,
     or (ii) changes that are related to a general drop in stock prices in the
     United States resulting from political or economic turmoil.)

     of the Chief Executive Officer or President and the Controller of the

         (e) Consents, Approvals, Etc. All material consents, authorizations,
     orders and approvals of (or filings or registrations with) any governmental
     commission, board, other Governmental Entity or third parties required to
     be made or obtained by the Company and the Company Subsidiaries and
     affiliated entities in connection with the execution, delivery and
     performance of this Agreement shall have been obtained or made.

         (f) Stockholders Agreement. The Principal Stockholders who are required
     by the Voting Agreement to enter into the Stockholders Agreement,
     substantially in the form of Exhibit C attached hereto, and Parent shall
     have entered into such agreement, which shall remain in full force and
     effect.

         (g) Legal Opinion. Parent shall have received a written opinion from
     its counsel, Paul, Weiss, Rifkind, Wharton & Garrison, in form and
     substance reasonably satisfactory to it, to the effect that the Merger will
     constitute (i) a tax free reorganization within the meaning of Section
     368(a) of the Code or (ii) a transaction that, together with the
     Reincorporation (as defined herein) qualifies as an exchange under the
     provisions of Section 351 of the Code and which is treated for U.S. federal
     income tax purposes as a transfer of Company Common Stock by the
     shareholders of the Company to Parent in exchange for the Merger
     Consideration and such opinion shall not have been withdrawn.

         (h) Affiliate Letters. The Parent shall have received an executed copy

be satisfied if, but for such action or the consequences thereof, such condition
would otherwise be satisfied.

                                   ARTICLE X

                       TERMINATION, AMENDMENT AND WAIVER

     10.1 Termination.   This Agreement may be terminated and abandoned at any
time prior to the Effective Time, whether before or after the approval of
matters presented in connection with the Merger by the stockholders of Parent
and the Company:

         (a) by the mutual written consent of Parent and the Company.

         (b) by either of Parent or the Company:

               (i) if any required approval of the stockholders of Parent or the
         Company that is a condition to the obligations of Parent or the Company
         under Section 9.1 of this Agreement shall not have been obtained at the
         Company Stockholders Meeting or the special meeting of the Parent's
         stockholders to be

                                      A-60
<PAGE>   390

         held to consider approval of the issuance of Parent Common Stock to be
         issued in the Merger; or

               (ii) if any Governmental Entity shall have issued a final and
         nonappealable Injunction (which Injunction the parties have used their
         best efforts to lift), which permanently enjoins the Merger.

         (c) by the Company, if the Company Board shall elect to terminate this
     Agreement in order to recommend or approve a Superior Proposal, provided
     that (i) the Company has complied with all the terms of Section 7.1 and
     notified Parent in writing that it intends to terminate this Agreement in
     order to recommend or approve a Superior Proposal, attaching the most
     current version of such proposal to such notice, (ii) at any time after the
     third business day following written notification by the Company to Parent
     of the Company's intention to enter into a binding agreement with respect
     to such proposal, after taking into account any modifications to the
     transactions contemplated by this Agreement that Parent has then proposed
     in writing and not withdrawn, the Company Board has determined that such
     proposal is and continues to be a Superior Proposal and (iii) concurrently
     with the effectiveness of such termination, pays to Parent the termination
     fee under Section 10.2(b), it being understood on the date of the
     effectiveness of such termination, whether or not prior to such
     effectiveness, the Company may enter into an agreement with respect to such
     Superior Proposal which agreement, if entered into prior to such
     effectiveness must be conditioned upon the payment of the termination fee
     on the same date as provided herein. The termination under this Section
     10.1(c) shall not be effective until the Company has made payment to Parent
     of the amounts required to be paid pursuant to Section 10.2(b).

         (d) by Parent, if (i) the Company Board shall have resolved to or shall
     have (A) withdrawn, modified or changed in a manner adverse to Parent its
     approval or recommendation of this Agreement, (B) failed to include such
     recommendation in the Proxy Statement, (C) approved or recommended any
     Acquisition Proposal, (D) entered into a definitive agreement with respect
     to a Superior Proposal or (E) made a public announcement of its intention
     to take any of the foregoing actions or (ii) a tender offer or exchange
     offer for more than 15% of the outstanding shares of the Company Common
     Stock is commenced and the Company Board fails to recommend against
     acceptance of such tender offer or exchange offer by its stockholders
     (including by taking no position with respect to the acceptance of such
     tender offer or exchange offer by its stockholders).

         (e) by Parent, if it is not in material breach of its obligations under
     this Agreement, on or after the later of (x) October 31, 2000, or (y) 120
     days following the date on which Parent last made an initial announcement
     that it had entered into a definitive agreement for a Parent Transaction,
     if any of the conditions provided in Sections 9.1 and 9.3 of this Agreement
     have not been satisfied and have not been waived in writing by Parent prior
     to such date; provided that, if the Merger has not occurred by reason of
     the nonsatisfaction of the condition set forth in Section 9.1(b) hereof or
     the pendency of a non final Injunction, Parent shall have used

                                      A-61
<PAGE>   391

     its best efforts to cause such condition to be satisfied or have any such
     Injunction stayed or reversed.

         (f) by the Company, if it is not in material breach of its obligations
     under this Agreement, on or after October 31, 2000, if any of the
     conditions provided in Sections 9.1 and 9.2 of this Agreement have not been
     satisfied and have not been waived by the Company; provided, however, if
     the Merger has not occurred by reason of the nonsatisfaction of the
     condition set forth in Section 9.1(b) hereof or the pendency of a non-final
     Injunction, the Company shall have used its best efforts to cause such
     condition to be satisfied or have any such Injunction stayed or reversed.

         (g) by Parent, upon a breach of any material representation, warranty,
     covenant or agreement on the part of the Company set forth in this
     Agreement, or if any representation or warranty of the Company shall have
     become untrue, in either case such that the conditions set forth in either
     of Section 9.3(a) or 9.3(b) would not be satisfied (a "Terminating Company
     Breach"); provided, however, that, if such Terminating Company Breach is
     curable by the Company through the exercise of its reasonable best efforts
     and for so long as the Company continues to exercise such reasonable best
     efforts, Parent may not terminate this Agreement under this Section
     10.1(g).

         (h) by the Company, upon breach of any material representation,
     warranty, covenant or agreement on the part of Parent set forth in this
     Agreement, or if any representation or warranty of Parent shall have become
     untrue, in either case such that the conditions set forth in either of
     Section 9.2(a) or 9.2(b) would not be satisfied (a "Terminating Parent
     Breach"); provided, however, that, if such Terminating Parent Breach is
     curable by Parent through its reasonable best efforts and for so long as
     Parent continues to exercise such reasonable best efforts, the Company may
     not terminate this Agreement under this Section 10.1(h); or

         (i) by the Company if (i) as of a date not more than three business
     days before the expected Closing Date, the Average Parent Common Stock
     Price would be less than 69% of the Base Stock Price, (ii) irrevocable
     notice shall have been provided to Parent in accordance with the notice
     provisions hereunder indicating the Company's intention to terminate the
     Agreement, and (iii) within one business day of receipt of such notice,
     Parent shall not have agreed (by unilateral notice to the Company) to
     increase the number of shares of Parent Common Stock to be issued to the
     shareholders of the Company pursuant to the Merger such that as of the
     Closing Date, the aggregate value (based on the Average Parent Common Stock
     Price) of the Parent Common Stock to be received by the shareholders of the
     Company will be equal to the aggregate value (based on the Average Parent
     Common Stock Price) of Parent Common Stock they would have been entitled to
     receive if the Average Parent Common Stock Price were equal to the Floor
     Stock Price. In the event the Company serves the notice provided for in
     (ii) above, and the Parent does not agree to increase the number of shares
     in accordance with

                                      A-62
<PAGE>   392

     (iii) above, then the termination shall become effective immediately on the
     following business day.

     10.2 Effect of Termination.

     (a) In the event of the termination of this Agreement pursuant to Section
10.1 hereof, this Agreement shall forthwith become null and void and have no
effect, without any liability on the part of any party hereto or its
Representatives, affiliates, trustees, directors, officers or stockholders and
all rights and obligations of any party hereto shall cease except for the
agreements contained in Sections 8.6, 8.8 and 11.4 and this Section 10.2 which
shall survive the termination; provided, however, that nothing contained in this
Section 10.2 shall relieve any party from liability for any fraud or willful
breach of its representations or warranties or breach of its covenants or
agreements set forth in this Agreement.

     (b) In the event the Company shall have terminated this Agreement pursuant
to Section 10.1(c), or Parent shall have terminated this Agreement pursuant to
Section 10.1(d)(i), then the Company shall simultaneously with such termination
pay Parent a termination fee equal to $19.0 million (the "Termination Amount").
In the event that Parent shall have terminated this Agreement pursuant to
Section 10.1(d)(ii) and either (x) the Company shall have entered into a
definitive agreement with respect to the tender or exchange offer giving rise to
such termination or (y) the person making the tender or exchange offer giving
rise to such termination shall have accepted shares for payment pursuant to such
tender or exchange offer, the Company shall pay, upon the earlier of entering
into a definitive agreement and the acceptance of shares for payment, to the
Parent a termination fee equal to the Termination Amount.

     (c) Any payment required by this Section 10.2 shall be payable by the
Company to Parent by wire transfer of immediately available funds to an account
designated by Parent.

     (d) The Company acknowledges that the agreements contained in this Section
10.2 are an integral part of the transactions contemplated by this Agreement,
and that, without these agreements, Parent and MergerCo would not enter into
this Agreement; accordingly, if the Company fails to pay promptly the amounts
due pursuant to Section 10.2(b), and, in order to obtain such payment, Parent
commences a suit which results in a judgment against the Company for all or a
portion of such amounts, the Company shall pay to Parent's Expenses in
connection with such suit, together with interest on the amounts payable to
Parent at the prime rate of The Chase Manhattan Bank in effect on the date such
payment was required to be made.

     10.3 Amendment.   This Agreement may be amended by the parties hereto by an
instrument in writing signed on behalf of each of the parties hereto at any time
before or after any approval hereof by the stockholders of Parent and the
Company, but in any event following authorization by Parent Board and the
Company Board; provided, however, that after any such stockholder approval, no
amendment shall be made which by law requires further approval by the
stockholders without obtaining such approval.

         (a) The term "affiliate," as applied to any person, means any other
     person directly or indirectly controlling, controlled by, or under common
     control with, that person. For the purposes of this definition, "control"
     (including, with correlative meanings, the terms "controlling," "controlled
     by" and "under common control with"), as applied to any person, means the

<PAGE>   394

     power to direct or cause the direction of the management and policies of
     that person, whether through the ownership of voting securities, by
     contract or otherwise.

         (b) The term "business day" means any day, other than Saturday, Sunday
     or a federal holiday, and shall consist of the time period from 12:01 a.m.
     through 12:00 midnight Eastern time. In computing any time period under
     this Agreement, the date of the event which begins the running of such time
     period shall be included except that if such event occurs on other than a
     business day such period shall begin to run on and shall include the first
     business day thereafter.

         (c) The term "including" means, unless the context clearly requires
     otherwise, including but not limited to the things or matters named or
     listed after that term.

         (d) The term "person" shall include individuals, corporations, limited

     indirectly owned by Parent or the Company, as the case may be.

     11.3 Non-Survival of Representations, Warranties, Covenants and Agreements.
Except for Articles I, II and IV, the last sentence of Section 8.2(a), and
Sections 7.3, 8.4, 8.5, 8.6, 8.7 and 8.10 and this Article XI, none of the
representations, warranties, covenants and agreements contained in this
Agreement or in any instrument delivered pursuant to this Agreement shall
survive the Effective Time, and thereafter there shall be no liability on the
part of none of Parent, MergerCo or the Company or any of their respective
officers, directors or stockholders in respect thereof. Except as expressly set
forth in this Agreement, there are no representations or warranties of any party
hereto, express or implied.

     11.4 Miscellaneous.   This Agreement (i) constitutes, together with the
Confidentiality Agreement, Parent Disclosure Schedule and the Company Disclosure
Schedule, the entire agreement and supersedes all of the prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof, (ii) shall be binding upon and inure to
the benefits of the parties hereto and their respective successors and assigns
and is not intended to confer upon any other person (except as set forth below)
any rights or remedies hereunder and (iii) may be executed in two or more
counterparts which together shall constitute a single agreement. Except as
provided in Section 8.7, this Agreement is not intended to confer upon any
person other than the parties to this Agreement any rights or remedies under
this Agreement. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in the Delaware Courts (as

                                      A-65
<PAGE>   395

hereinafter defined), this being in addition to any other remedy to which they
are entitled at law or in equity.

     11.5 Assignment.   Except as expressly permitted by the terms hereof,
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by either party hereto without the prior written consent of
the other party, except that Parent shall assign all of its rights, interests
and obligations under this Agreement to ATX, upon consummation of the ATX
Transaction if such consummation occurs prior to the Closing provided that,
notwithstanding such assignment, Parent shall remain liable under this
Agreement. If such assignment occurs, then (i) ATX will acquire the Company by
merging a wholly owned first-tier domestic subsidiary of ATX into the Company,
(ii) the acquisition of Parent by ATX will be consummated after the
Reincorporation of Parent, and (iii) the acquisition of Parent by ATX will be
structured so that it will be treated for U.S. federal income tax purposes as a
transfer of stock of Parent by Parent stockholders in exchange for stock issued
by ATX.

     11.6 Severability.   If any provision of this Agreement, or the application
thereof to any person or circumstance is held invalid or unenforceable, the
remainder of this Agreement, and the application of such provision to other
persons or circumstances, shall not be affected thereby, and to such end, the
provisions of this Agreement are agreed to be severable.

     11.7 Choice of Law/Consent to Jurisdiction.   All disputes, claims or
controversies arising out of this Agreement, or the negotiation, validity or
performance of this Agreement, or the Transactions shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
its rules of conflict of laws. Each of Parent, MergerCo and the Company hereby
irrevocably and unconditionally consents to submit to the sole and exclusive
jurisdiction of the courts of the State of Delaware and of the United States of
America located in the State of Delaware (the "Delaware Courts") for any
litigation arising out of or relating to this Agreement, or the negotiation,
validity or performance of this Agreement, or the Transactions (and agrees not
to commence any litigation relating thereto except in such courts), waives any
objection to the laying of venue of any such litigation in the Delaware Courts
and agrees not to plead or claim in any Delaware Court that such litigation
brought therein has been brought in any inconvenient forum. Each of the parties
hereto agrees, (a) to the extent such party is not otherwise subject to service
of process in the State of Delaware, to appoint and maintain an agent in the
State of Delaware as such party's agent for acceptance of legal process, and (b)
that service of process may also be made on such party by prepaid certified mail
with a proof of mailing receipt validated by the United States Postal Service
constituting evidence of valid service. Service made pursuant to (a) or (b)
above shall have the same legal force and effect as if served upon such party
personally within the State of Delaware. For purposes of implementing the
parties' agreement to appoint and maintain an agent for service of process in
State of Delaware, each such party does hereby appoint The Corporation Trust
Company, 1209 Orange Street, Wilmington, New Castle County, Delaware 19801, as
such agent.

     11.8 Incorporation.   The Parent Disclosure Schedule and the Company
Disclosure Schedule and all Exhibits and Schedules attached hereto and thereto
and referred to herein and therein respectively are hereby incorporated herein
and made a part hereof for all purposes as if fully set forth herein.

     11.9 The Headings.   The headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     11.10 No Agreement Until Executed.   Irrespective of negotiations among the
parties or the exchanging of drafts of this Agreement, this Agreement shall not
constitute or be deemed to evidence a contract, agreement, arrangement or
understanding among the parties hereto unless and until (i) the Company Board
has approved the terms of this Agreement, including, without limitation, for
purposes of Section 203 of the DGCL and any applicable provision of the Company
Certificate, (ii) Parent Board has approved the terms of this Agreement,
including, without limitation, for purposes of the DGCL and Bermuda law and any
applicable provisions of Parent Certificate and (ii) this Agreement is executed
by the parties hereto.

     11.11   Obligations of Parent and of the Company.   Whenever this Agreement
requires a Parent Subsidiary to take any action, that requirement shall be
deemed to include an undertaking on the part of Parent to cause that Parent
Subsidiary to take that action. Whenever this Agreement requires a Company
Subsidiary to take any action, that requirement shall be deemed to include an
undertaking on the part of the Company to cause that Company Subsidiary to take
that action and, after the Effective Time, on the part of the Surviving
Corporation to cause that Company Subsidiary to take that action.

signed on behalf of each of the parties thereto at any time before or after any
approval thereof by the stockholders of Parent and the Company;

     WHEREAS, the parties hereto wish to amend the Merger Agreement as set forth
below; and

     WHEREAS, following execution of this Amendment, Parent, as the sole
stockholder of MergerCo, will approve this Amendment in accordance with the
DGCL.

     NOW, THEREFORE, in consideration of the mutual promises and agreements set
forth herein, the receipt and adequacy of which are hereby acknowledged, the
parties agree as follows:

     1. Section 1.1.   The third and fourth sentences of Section 1.1 of the
Merger Agreement are hereby amended by deleting such sentences in their entirety
and replacing them with the following sentence:

         "At the Effective Time, the certificate of incorporation of the
         Surviving Corporation shall be amended so as to read in its entirety as
         set forth in Exhibit D hereto and the bylaws of MergerCo in effect
         immediately prior to the Effective Time shall be the bylaws of the
         Surviving Corporation until amended in accordance with applicable law."

     2. Section 1.2.   The first sentence of Section 1.2 of the Merger Agreement
is hereby amended by deleting the words "MergerCo and" in such sentence.

     3. Section 3.1(b).   The first sentence of Section 3.1(b) of the Merger
Agreement is hereby amended by inserting the following words after the words

         ", and other than shares of Company Common Stock as to which appraisal
         rights are duly demanded and perfected under the DGCL and not withdrawn
         or lost"

<PAGE>   399

     5. Article 3.   Article 3 of the Merger Agreement is hereby amended by
inserting the following sections at the end of such article:

     Section 3.3   Appraisal Rights.   Any shares of Company Common Stock as to
     which the holder thereof shall have properly demanded appraisal in
     accordance with the requirements of Section 262 of the DGCL (any holder
     duly making such demand is referred to herein as a "Dissenting
     Stockholder") shall not be converted into the right to receive the Merger
     Consideration, unless and until such holder shall have failed to perfect,
     or shall have effectively withdrawn or lost, the right to appraisal of and
     payment for such shares of Common Stock under the DGCL, but instead such
     holder shall be entitled only to such rights as are provided for under
     Section 262 of the DGCL. If a Dissenting Stockholder fails to perfect, or
     effectively withdraws or loses the right to receive payment for such shares
     of Common Stock, pursuant to Section 262 of the DGCL, such shares of
     Company Common Stock shall be deemed converted as of the Effective Time
     (but without any interest thereon) as provided in Section 3.1.

     Section 3.4   Effect of the ATX Transaction.   In the event the ATX
     Transaction (as defined) is consummated (the date of such consummation
     being referred to as the "ATX Closing Date") prior to the Closing and the
     rights and obligations of Parent are assigned in accordance with Section
     11.5 of this Agreement (the "ATX Assignment"), the following shall occur:

         (i) in lieu of the number of shares of Parent Common Stock otherwise to
     be received (A) by the holders of Company Common Stock as part of the
     Merger Consideration and (B) with respect the Assumed Options, a like
     number of shares of common stock of ATX ("ATX Stock") shall be
     automatically substituted for shares of Parent Common Stock, on precisely
     the same terms, and based on the same adjustments to the Exchange Ratio and
     the Option Exchange Ratio, as would be applicable if such holders received
     shares of Parent Common Stock in accordance with the terms of this
     Agreement and all references to Stock Consideration shall include ATX Stock
     in lieu of Parent Common Stock;

         (ii) unless the context otherwise requires, all references to Parent
     Common Stock in this Agreement shall mean ATX Stock following the ATX
     Closing Date; and

         (iii) if the context requires, all references to Parent in Articles I,
     II, II or IV of this Agreement shall mean ATX following the ATX Closing
     Date, provided the representations, warranties, covenants and other
     agreements of Parent shall continue to refer to Parent before and after the
     ATX Closing Date; and

         (iv) the acquisition of the Company by Parent will be structured so
     that it will be treated for U.S. federal income tax purposes as a transfer
     of Company Common Stock by Company stockholders in exchange for ATX Stock.

amended by deleting this section in its entirety and replacing it with the
following:

     amended through the date of this Agreement that are incorporated by
     reference in, as exhibits to the Company's registration statement on Form
     S-8 dated August 12, 1999 and all comparable corporate organizational
     documents of the Company Subsidiaries made available to Parent by the
     Company are complete and correct copies of those documents. All such
     corporate organizational documents of the Company and the Company
     Subsidiaries are listed on Section 5.1(e) of the Company Disclosure
     Schedule. The Company Certificate and Company Bylaws and all comparable
     organizational documents of the Company Subsidiaries are in full force and
     effect. The Company is not in violation of any of the provisions of the
     Company Certificate or Company Bylaws."

     7. Section 6.2.   The third sentence of Section 6.2 of the Merger Agreement
is hereby amended by deleting this sentence in its entirety and replacing this
sentence with the following:

         "The Board of Directors of MergerCo (the "MergerCo Board") has approved
     and declared advisable this Agreement and the Transactions and, immediately
     following the execution of this Agreement by MergerCo, the stockholders of
     MergerCo will approve this Agreement and the Transactions."

     8. Section 8.11.   Section 8.11(b) of the Merger Agreement is hereby
amended by inserting the words ", as amended," prior to the words (the "ATX
Transaction").

     9. Section 11.5.   Section 11.5 of the Merger Agreement is hereby amended
by deleting this section in its entirety and replacing it with the following:

     "Section 11.5.   Assignment.   Except as expressly permitted by the terms
hereof, neither this Agreement nor any of the rights, interests or obligations
hereunder shall be assigned by either party hereto without the prior written
consent of the other party, provided, however that, all of Parent's rights,
interests and obligations under this Agreement shall be automatically assigned
to ATX, upon consummation of the ATX Transaction if such consummation occurs
prior to the Closing and provided further that, notwithstanding such assignment,
Parent shall remain liable under this Agreement. If such assignment occurs, then
(i) ATX will acquire the Company by merging a wholly owned first-tier domestic
subsidiary of ATX into the Company, (ii) the acquisition of Parent by ATX will
be consummated after the Reincorporation of Parent, and (iii) the provisions set
forth in Section 3.4 of this Agreement shall become immediately effective."

     10. Exhibit D.   The Merger Agreement is hereby amended by inserting
Exhibit D following Exhibit C to the Merger Agreement.

     11. MISCELLANEOUS.

     (a) Severability.   If any one or more of the provisions contained herein,

herein, the provisions of the Merger Agreement are and shall remain in full
force and effect.

                     FORM OF REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT, dated as of                , 2000 (the
"Agreement"), by and between [CoreComm Limited], a                   corporation
("CoreComm" or the "Company") and the holders of Common Stock (as hereinafter
defined) listed on Schedule 1 attached hereto (each a "Stockholder" and,
collectively, the "Stockholders").

     WHEREAS, pursuant to an Agreement and Plan of Merger, dated as of March
   , 2000 (the "Merger Agreement"), by and among the Company, CoreComm Group Sub
I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent, and
Voyager.net, Inc., a Delaware corporation, and, with respect to certain
provisions thereof, each of the Stockholders is entitled to receive shares of
the Company's common stock, par value $.01 per share (the "Common Stock") and
cash;

     WHEREAS, it is a condition to the consummation of the merger and the other
transactions contemplated by the Merger Agreement that the Company grant to the
Stockholders the registration rights and other rights set forth herein; and

     In consideration of the mutual covenants and agreements set forth herein
and for good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto agree as follows:

     1. General; Securities Subject to this Agreement.

         1.1 Grant of Rights.   The Company hereby grants registration rights to
     the Stockholders upon the terms and subject to the conditions set forth in
     this Agreement. Capitalized terms used herein and not defined shall have
     the meanings assigned to such terms in the Merger Agreement.

         1.2 Registrable Securities.   For the purposes of this Agreement,
     "Registrable Securities" means any shares of Common Stock issued to the
     Stockholders pursuant to the Merger Agreement; provided, however, that (i)
     shares shall cease to be Registrable Securities for purposes of this
     Agreement when a registration statement covering such Registrable
     Securities has been declared effective under the Securities Act by the
     Commission and all such Registrable Securities have been disposed of
     pursuant to such effective registration statement and (ii) the securities
     of a Stockholder shall be deemed not to be Registrable Securities at any
     time when the entire amount of such Stockholder's Registrable Securities
     proposed to be sold in a single sale are or, in the opinion of counsel
     satisfactory to the Company, in its reasonable judgment, may be distributed
     to the public pursuant to Rule 144 (or any successor provision then in
     effect) under the Securities Act.

         1.3 Stockholders of Registrable Securities.   A Person is deemed to be
     a holder of Registrable Securities whenever such Person (i) is a party to
     this Agreement (or a permitted transferee thereof) and (ii) owns of record
     Registrable Securities. If the Company receives conflicting instructions,
     notices or elections from two or more

                                      A-74
<PAGE>   404

     Persons with respect to the same Registrable Securities, the Company may
     act upon the basis of the instructions, notice or election received from
     the registered owner of such Registrable Securities.

     2. Demand Registration Rights.

         2.1 Demand Registration.

         (a) At any time on or after six (6) months from the date of this
     Agreement, the Stockholders may make a written request (specifying the
     intended method of disposition) (such Stockholders, the "Initiating
     Stockholders") for registration under the Securities Act (a "Demand
     Registration") of all or part of the shares of Common Stock which
     constitute such Initiating Stockholders' Registrable Securities; provided,
     however, that, (i) the Company shall not be required to effect more than
     one (1) Demand Registration pursuant to this Agreement, (ii) the number of
     the shares of Common Stock proposed to be registered by the Initiating
     Stockholders shall not be less than 1,500,000 shares (subject to
     appropriate adjustments to reflect stock splits, stock dividends, corporate
     recapitalizations or similar transactions) as of the date of the request,
     and (iii) the Initiating Stockholders shall be the holders as of the date
     of the request of at least 43.5% of the then outstanding shares of Common
     Stock that constitute Registrable Securities hereunder.

         (b) If at the time of any request to register Registrable Securities
     pursuant to this Section 2.1, the Company is engaged or plans to engage in
     within ninety (90) days of the time of such request in a registered public
     offering or any other activity which, in the good faith determination of
     the Board of Directors of the Company, would be required to be disclosed
     under applicable law as a result of such request or would be materially and
     adversely affected by the requested registration (each, a "Company Event"),
     then the Company may at its option direct that such request be delayed for
     a reasonable period of time not in excess of three (3) months from the
     effective date of such offering or the date of completion of such other
     activity, as the case may be, such right to delay a request to be exercised
     by the Company not more than once in any 365-day period. In addition, the
     Company shall not be required to effect any registration within three (3)
     months after the effective date of any other Registration Statement of the
     Company. Within ten days after receipt of a request for a Demand
     Registration, the Company shall give written notice (the "Notice") of such
     request to all other Stockholders holding the class of stock to which such
     Demand Registration relates and shall include in such registration all
     Registrable Securities of that class that the Company has received written
     requests for inclusion therein within 15 days after the Notice is given.
     Thereafter, in the case of Demand Registration, the Company may elect to
     include in such registration additional shares of Common Stock issued by
     the Company. All requests made pursuant to this Section 2.1 shall specify
     the class and aggregate number of Registrable Securities to be registered.

         2.2 Effective Demand Registration.   The Company shall use reasonable
     commercial efforts to cause any Demand Registration to become effective not
     later than
                                      A-75
<PAGE>   405

     ninety (90) days after it receives a request under Section 2.1 hereof and
     to remain effective for the lesser of (i) the period during which all
     Registrable Securities registered in the Demand Registration are sold and
     (ii) one hundred and twenty (120) days; provided, however, that if the
     Initiating Stockholders request the Company to withdraw such registration,
     other than as the result of a breach by the Company, it shall constitute a
     Demand Registration unless the Initiating Stockholders promptly pay all of
     the costs and expenses incurred by the Company in connection with such
     registration.

         2.3 Underwriting Procedures.

         (a) The offering of Registrable Securities pursuant to a Demand
     Registration shall be in the form of a firm commitment underwritten
     offering and the managing underwriter and other underwriters selected for
     such offering shall be selected by the Company, provided that the managing
     underwriter and other underwriters are reasonably acceptable to the
     Initiating Stockholders (having due regard to the experience and
     relationship with the Company of the managing underwriter and the other
     underwriters) (the "Approved Underwriter"). In such event, if the Approved
     Underwriter advises the Company in writing that in its opinion the
     aggregate amount of such Registrable Securities requested to be included in
     such offering is sufficiently large to have a material adverse effect on
     the success of such offering, the Company shall include in such
     registration only the aggregate amount of Registrable Securities that in
     the opinion of the Approved Underwriter may be sold without any such
     material adverse effect and shall reduce pro rata based on the number of
     Registrable Securities included in the request for Demand Registration, the
     amount of Registrable Securities to be included by each Stockholder in such
     registration.

         (b) Distribution by Underwriters. The managing underwriter or
     underwriters selected for any offering shall enter into an agreement with
     the Company and the Stockholders whereby the underwriters shall be
     prohibited from (i) distributing 5% or greater of the Registrable
     Securities to any Person in connection with the initial placement of the
     Registrable Securities for the offering and from (ii) distributing 5% or
     greater of the Registrable Securities to any Person for 90 days after such
     initial placement.

     3. Incidental or "Piggy-Back" Registration Rights.

         3.1 Notice of Registration.   If, at any time or from time to time
     prior to the second anniversary of the date hereof, the Company shall
     determine to register any of its Common Stock for sale in an Underwritten
     Offering for its own account (other than a registration relating to (i) a
     registration of an employee compensation plan or arrangement adopted in the
     ordinary course of business on Form S-8 (or any successor form) or any
     dividend reinvestment plan or (ii) a registration of securities on Form S-4
     (or any successor form) including, without limitation, in connection with a
     proposed issuance in exchange for securities or assets of, or in connection
     with a merger or consolidation with another corporation), the Company will
     promptly give to the Stockholders written notice thereof, and include in
     such
                                      A-76
<PAGE>   406

     registration (subject to Section 3.2) all the Registrable Securities
     specified in a written request made by any one or more of the Stockholders
     within ten days after such Stockholder's receipt of such written notice
     from the Company ("Incidental Registration"). The right of such Stockholder
     to have Registrable Securities included in a registration pursuant to this
     Section 3.1 shall be conditioned upon such Stockholder's entering into
     (together with the Company and/or the other holders, if any, distributing
     their securities through such underwriting) an underwriting agreement in
     customary form with the managing underwriter or underwriters selected for
     such underwriting by the Company (the "Company Underwriter").

         3.2 Cutback.   If the lead managing underwriter of an offering covered
     by Section 3.1 shall advise the Company in writing on or before the date
     five days prior to the date then scheduled for such offering that, in its
     opinion, the amount of Common Stock (including Registrable Securities)
     requested to be included in such registration exceeds the amount which can
     be sold in such offering without adversely affecting the distribution of
     the Common Stock being offered, then the Company will include in such
     registration: first, any shares proposed to be offered by the Company;
     second, Registrable Securities requested to be registered by the
     Stockholders and any other shares requested by other stockholders of the
     Company, including the Stockholders, to be included in such registration,
     allocated, if necessary, pro rata among the Stockholders and such other
     holders requesting such registration on the basis of the number of the
     shares Beneficially Owned at the time, provided, however, that in the event
     the Company will not, by virtue of the foregoing cut-back mechanism,
     include in any such registration all of the Registrable Securities
     requested to be included in such registration, the Stockholders may, upon
     written notice to the Company given within three days of the time the
     Stockholders first are notified of such matter, reduce the amount of
     Registrable Securities they desire to have included in such registration,
     whereupon only the Registrable Securities, if any, they desire to have
     included will be considered for such inclusion.

         3.3 Right of Termination.   The Company shall have the right to
     terminate or withdraw any registration initiated by it under Section 3.2
     prior to the effectiveness of such registration whether or not the
     Stockholders have elected to include Registrable Securities in such
     registration.

     4. Provisions Applicable to Demand and Piggy-Back Registrations.

         4.1 Expenses.   The Company shall pay all Registration Expenses (as
     defined in Section 6 hereof) incurred in connection with any registration
     pursuant to Section 2 or 3 hereto, unless such registration fails to become
     effective as a result of the fault of one or more Stockholders, in which
     case the Company will not be required to pay the Registration Expenses
     incurred with respect to the offering of such Stockholder's or
     Stockholders' Registrable Securities. The Registration Expenses incurred
     with respect to the offering of such Stockholder's or Stockholders'
     Registrable Securities shall be the product of (a) the aggregate amount of
     all

                                      A-77
<PAGE>   407

     Registration Expenses incurred in connection with such registration and (b)
     the ratio that the number of such Registrable Securities bears to the total
     number of Registrable Securities included in the registration.

         4.2 Holdback Agreements.   Each Stockholder agrees not to effect any
     public sale or distribution of any Registrable Securities being registered
     or of any securities convertible into or exchangeable or exercisable for
     such Registrable Securities, including a sale pursuant to Rule 144 under
     the Act, during the ninety (90) day period beginning on the effective date
     of any Demand Registration or Incidental Registration or other underwritten
     offering in which such Stockholder is participating (except as part of such
     registration), if and to the extent requested by any other Stockholders, in
     the case of a non-underwritten public offering, or if and to the extent
     requested by the Approved Underwriter or Company Underwriter, in the case
     of an underwritten public offering.

     5. Registration Procedures.

     In connection with any registration statement filed pursuant to this
Agreement, the Company will, as expeditiously as possible:

         (a) in connection with a request pursuant to this Agreement, prepare
     and file with the Commission, after receipt of a request to file a
     registration statement with respect to Registrable Securities, a
     registration statement on any form for which the Company then qualifies or
     which counsel for the Company shall deem appropriate and which form shall
     be available for the sale of such Registrable Securities in accordance with
     the intended method of distribution thereof and, if the offering is an
     underwritten offering, shall be reasonably satisfactory to the managing
     underwriter or underwriters, and use its best efforts to cause such
     registration statement to become effective; provided, however, that before
     filing a registration statement or prospectus or any amendments or
     supplements thereto, the Company shall (i) furnish to the counsel selected
     by the Stockholder or Stockholders making the demand, if any, copies of all
     such documents proposed to be filed, and (ii) notify such counsel and each
     seller or prospective seller of Registrable Securities of any stop order
     issued or threatened by the Commission and take all reasonable actions
     required to prevent the entry of such stop order or to remove it if
     entered;

         (b) in connection with a registration pursuant to this Agreement,
     prepare and file with the Commission such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     as may be necessary to keep such registration statement effective for a
     period of not more than one hundred twenty (120) days (or such shorter
     period that will terminate when all Registrable Securities covered by such
     registration statement have been disposed of);

         (c) furnish to each seller of Registrable Securities such number of
     copies of the registration statement, each amendment and supplement thereto
     (in each case including all exhibits thereto), the prospectus included in
     such registration statement (including each preliminary prospectus) and
     such other documents as each seller

                                      A-78
<PAGE>   408

     may reasonably request in order to facilitate the disposition of the
     Registrable Securities owned by such seller;

         (d) use reasonable efforts to register or qualify such Registrable
     Securities under such other securities or "blue sky" laws of such
     jurisdictions as any seller or underwriter reasonably requests in writing
     and to do any and all other acts and things that may be reasonably
     necessary or advisable to register or qualify for sale in such
     jurisdictions the Registrable Securities owned by such seller; provided,
     however, that the Company shall not be required to (i) qualify generally to
     do business in any jurisdiction where it is not then so qualified, (ii)
     subject itself to taxation in any such jurisdiction, (iii) consent to
     general service of process in any such jurisdiction or (iv) provide any
     undertaking required by such other securities or "blue sky" laws or make
     any change in its charter or by-laws that the Board of Directors of the
     Company determines in good faith to be contrary to the best interest of the
     Company and its stockholders;

         (e) use reasonable efforts to cause the Registrable Securities covered
     by such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary by virtue of
     the business and operations of the Company to enable the seller or sellers
     thereof or the underwriters, if any, to consummate the disposition of such
     Registrable Securities;

         (f) notify each seller of such Registrable Securities at any time when
     a prospectus relating thereto is required to be delivered under the
     Securities Act of the happening of any event as a result of which the
     prospectus included in such registration statement contains an untrue
     statement of a material fact or omits to state any material fact required
     to be stated therein or necessary to make the statements therein, in light
     of the circumstances under which they were made, not misleading, and
     prepare and file with the Commission as soon thereafter as practicable,
     after consultation with the Initiating Stockholders, a supplement or
     amendment to such prospectus so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus will not contain
     an untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading;

         (g) enter into customary agreements (including an underwriting
     agreement in customary form, if the offering is an underwritten offering)
     and take such other actions as are reasonably required in order to expedite
     or facilitate the disposition of such Registrable Securities;

         (h) otherwise use reasonable efforts to comply with all applicable
     rules and regulations of the Commission; and

         (i) use reasonable efforts to cause all Registrable Securities covered
     by the registration statement to be listed on each securities exchange or
     market, if any, on which similar securities issued by the Company are then
     listed, provided that the applicable listing requirements are satisfied.

                                      A-79
<PAGE>   409

     The Company may require each seller or prospective seller of Registrable
Securities as to which any registration is being effected to furnish to the
Company such information regarding the distribution of such securities and other
matters as may be required to be included in the registration statement.

     Each holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
paragraph (f) of this Section 5, such holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such holder's receipt of the copies
of the supplemented or amended prospectus contemplated by paragraph (f) of this
Section 5 and, if so directed by the Company, such holder shall deliver to the
Company all copies, other than permanent file copies then in such holder's
possession or copies delivered to prospective purchasers, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice, the Company shall extend the
period during which such registration statement shall be maintained effective
pursuant to this Agreement (including the period referred to in paragraph (b) of
this Section 5) by the number of days during the period from and including the
date of the giving of such notice pursuant to paragraph (f) of this Section 5 to
and including the date when each seller of Registrable Securities covered by
such registration statement shall have received the copies of the supplemented
or amended prospectus contemplated by paragraph (f) of this Section 5.

     6. Registration Expenses.   The Company shall pay all expenses incident to
its performance of or compliance with this Agreement; provided, however, that
the Company shall not pay the costs and expenses of any Stockholder relating to
underwriters' commissions and discounts relating to Registrable Securities to be
sold by such Stockholder, brokerage fees, transfer taxes or the fees or expenses
of any counsel, accountants or other representatives retained by the
Stockholders, individually or in the aggregate. All of the expenses described in
this Section 6 that are to be paid by the Company are herein called the
"Registration Expenses."

     7. Indemnification; Contribution.

         7.1 Indemnification by the Company.   The Company agrees to indemnify,
     in the case of any registration statement filed pursuant to this Agreement,
     each seller of any Registrable Securities covered by such registration
     statement, each other person who participates as an underwriter in the
     offering or sale of such securities, and each person, if any, who controls
     such seller or any such underwriter within the meaning of the Securities
     Act (each an "Indemnified Party" and collectively, the "Indemnified
     Parties") against any losses, claims, damages or liabilities to which such
     Indemnified Party may become subject under the Securities Act or otherwise,
     insofar as such losses, claims, damages or liabilities arise out of or are
     based upon any untrue statement or alleged untrue statement of any material
     fact contained in any registration statement under which such securities
     were registered under the Securities Act, any preliminary prospectus, final
     prospectus or summary prospectus contained therein, or any amendment or
     supplement thereto, or any omission or

                                      A-80
<PAGE>   410

     alleged omission to state a material fact required to be stated therein or
     necessary to make the statements therein in light of the circumstances in
     which they were made not misleading, or any violation by the Company of the
     Securities Act or any rule or regulation thereunder applicable to the
     Company; provided, however, that the Company shall not be liable to the
     extent that any loss, claim, or liability arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in such registration statement, any such preliminary
     prospectus, final prospectus, summary prospectus, amendment or supplement
     in reliance upon and in conformity with written information furnished to
     the Company by or on behalf of such Indemnified Party expressly for use in
     the Registration Statement; provided, further, that the Company shall not
     be liable to any seller of Registrable Securities (or to any person who
     acts as an underwriter in such sale or who controls such seller) to the
     extent that any loss, claim, or liability arises out of an untrue
     statement, alleged untrue statement, omission, or alleged omission made in
     any preliminary prospectus if either (a)(i) such seller failed to send or
     deliver a copy of the prospectus with or prior to written confirmation of
     the sale by such seller to the person asserting the claim and (ii) the
     prospectus would have corrected such untrue statement, alleged untrue
     statement, omission or alleged omission; or (b)(x) such untrue statement,
     alleged untrue statement, omission or alleged omission is corrected in an
     amendment or supplement to the prospectus and (y) having been furnished by
     or on behalf of the Company with copies of the prospectus as so amended or
     supplemented, such seller fails to deliver such prospectus as so amended or
     supplemented, with or prior to the written confirmation of the sale by such
     seller to the person asserting the claim.

         7.2 Indemnification by Stockholders.   In connection with any
     registration statement in which a Stockholder is participating, each such
     Stockholder shall furnish to the Company in writing such information and
     affidavits with respect to such Stockholder as the Company reasonably
     requests for use in connection with any such registration statement or
     prospectus and agrees to indemnify, to the fullest extent permitted by law,
     the Company, its officers, directors and agents and each person, if any,
     who controls the Company (within the meaning of the Securities Act) against
     any and all losses, claims, damages, and liabilities resulting from any
     untrue or alleged untrue statement of a material fact or any omission or
     alleged omission of a material fact required to be stated in any
     registration statement, prospectus or preliminary prospectus or any
     amendment thereof or supplement thereto or necessary to make the statements
     therein (in the case of a prospectus, in light of the circumstances under
     which they were made) not misleading, to the extent that such untrue or
     alleged untrue statement or omission is contained in or omitted from, as
     the case may be, any information or affidavit with respect to such
     Stockholder so furnished in writing by such Stockholder expressly for use
     in any such prospectus or preliminary prospectus; provided, however, that
     the liability of such Stockholder shall not exceed the net proceeds
     received by such Stockholder from the sale of its Registrable Securities.
     Each Stockholder also shall indemnify any underwriters of the Registrable
     Securities, their officers and directors and each

                                      A-81
<PAGE>   411

     person who controls such underwriters (within the meaning of the Securities
     Act) to the same extent as provided above with respect to the
     indemnification of the Company; provided, however, that the indemnification
     of such Stockholder shall be limited to the net proceeds received by such
     Stockholder from the sale of its Registrable Securities.

         7.3 Contribution.   If the indemnification provided for in this Section
     7 is unavailable to any Indemnified Party hereunder in respect of any
     losses, claims, damages, liabilities or expenses referred to herein, then
     the indemnifying party, to the extent such indemnification is unavailable,
     in lieu of indemnifying such Indemnified Party, shall contribute to the
     amount paid or payable by such Indemnified Party as a result of such
     losses, claims, damages, liabilities or expenses in such proportion as is
     appropriate to reflect the relative fault of the indemnifying party and
     Indemnified Parties in connection with the actions that resulted in such
     losses, claims, damages, liabilities or expenses. The relative fault of
     such indemnifying party and Indemnified Parties shall be determined by
     reference to, among other things, whether any action in question, including
     any untrue or alleged untrue statement of a material fact or omission or
     alleged omission to state a material fact, has been made by, or relates to
     information supplied by, such indemnifying party or Indemnified Parties,
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such action.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7.3 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person.

     8. Definitions.   As used herein, the following terms shall have the

     of any securities of the Company which would allow such holder or
     prospective holder to include such securities in any registration filed
     under Section 2.1(a) hereof, unless under the terms of such agreement, such
     holder or prospective holder may include such securities in any such

                         FORM OF STOCKHOLDERS AGREEMENT

     AGREEMENT dated as of                   , 2000 among [CoreComm Limited], a
                  corporation (the "Company"), and each of the Persons listed on
Schedule A hereto (each, a "Stockholder").

     WHEREAS, pursuant to an Agreement and Plan of Merger, dated as of March
   , 2000 (the "Merger Agreement"), by and among the Company, [MergerCo], a
Delaware corporation and a wholly-owned subsidiary of the Company ("MergerCo"),
and Voyager.net, Inc., a Delaware corporation ("Voyager"), MergerCo is being
merged with and into Voyager (the "Merger") and as a result thereof each share
of Voyager's common stock, par value $.01 per share, issued and outstanding
immediately prior to the effective time of the Merger (the "Effective Time") is
being converted into                   shares the Company's common stock, par
value $.01 per share (the "Common Stock"), as well as the right to receive cash;
and

     WHEREAS, it is a condition to the obligation of the Company to consummate
the Merger, that the Company and each of Stockholders enter into this Agreement;
and

     WHEREAS, each Stockholder has independently determined that the Merger is
in its best interest and each Stockholder wishes to facilitate the consummation
of the Merger by entering into this Agreement and agreeing to be bound by the
terms hereof;

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, provisions and covenants herein contained, each Stockholder and the
Company hereby agree as follows:

     Section 1. Covenants of Stockholders with Respect to Voting Securities of
the Company.

     During the term of this Agreement and subject to all of the provisions
hereof, each Stockholder and the Company agree as follows:

     1.1 Acquisition of Voting Securities.   Each Stockholder shall not acquire,
agree to acquire or offer or propose to acquire, directly or indirectly, or in
conjunction with or through any Person, record or beneficial ownership of any
Voting Securities (as hereinafter defined), except (i) through the exercise of
conversion rights, if any, of Voting Securities; (ii) by way of stock splits,
reclassifications or stock dividends or other distributions or offerings made on
a pro rata basis to holders of Voting Securities or any class of Voting
Securities; (iii) from another Stockholder by bequest (including, without
limitation, through the creation of a trust), gift, will, pledge, hypothecation
or otherwise in accordance with clause (i) of Section 1.6 hereof; (iv) pursuant
to a bequest or similar gift or transfer from a Person who is not a Stockholder,
including, without limitation, through the creation of a trust for the benefit
of a Stockholder; (v) pursuant to a will or the laws of descent and distribution
from a Person who is not a Stockholder; or (vi) pursuant to the exercise of
stock options or the receipt of other compensation or benefits involving Voting
Securities granted to a Stockholder in such Stockholder's

                                      A-88
<PAGE>   418

capacity (if applicable) as an employee of the Company or any subsidiary of the
Company; provided, however, that if, in connection with the transfer of Voting
Securities to a Stockholder pursuant to clauses (iv) and (v) of this Section
1.1, a trust, corporation or other entity is formed for the purpose of holding
Voting Securities for the benefit of a Stockholder (other than solely as an
income beneficiary of a trust), then, as a condition precedent to the receipt by
such Stockholder of any direct or indirect beneficial interest in such Voting
Securities, such trust, corporation or other entity shall agree to be bound by
the terms and conditions of a stockholder agreement having the same or
substantially the same terms and conditions as this Agreement.

     If a Stockholder shall acquire, directly or indirectly, record or
beneficial ownership of, or the right to acquire, any Voting Securities in
contravention of this Agreement, then such Stockholder shall promptly notify the
Company, and the Company, in its sole discretion, may either (x) purchase (or
cause its designee(s) to purchase) any or all of such acquired Voting Securities
at a price equal to the price paid by such Stockholder or (y) require such
Stockholder to dispose of, within 30 days from the date on which the Company
requests such Stockholder to do so, only in accordance with the provisions of
Section 1.6 (ii) or (iv), the Voting Securities acquired in violation of this
Section 1.1, provided that any sale may be delayed to avoid a violation of
Section 16(b) of the Exchange Act or any other provisions of the Exchange Act or
Securities Act, including, without limitation, any applicable volume limits
under Rule 144 of the Securities Act, or any successor rules or regulations
permitting sales of unregistered or otherwise restricted securities. Each
Stockholder hereby acknowledges that any acquisition of Voting Securities in
contravention of this Agreement shall constitute a breach of this Agreement and
that the Company's right to purchase or require the disposition of Voting
Securities pursuant to this Section 1.1 shall not be exclusive and shall be in
addition to any other rights and remedies the Company may have in connection
with a breach of this Agreement.

     For the purposes of this Agreement, "Voting Securities" means all
securities of the Company, or any successor to the Company, entitling the holder
thereof to vote as a stockholder for any purpose or under any circumstance or
any securities convertible into or exchangeable for under any circumstance such
securities or any rights, warrants or options to acquire (through purchase,
exchange, conversion or otherwise) any such securities under any circumstance.

     1.2 Voting of Voting Securities.   Each Stockholder shall vote or direct
the vote of all Shares of Voting Securities that are (a) acquired pursuant to
the Merger, (b) acquired by a Stockholder pursuant to Section 1.1, (c) held in
trusts, corporations or other entities formed as contemplated by Section 1.6 or
(d) otherwise hereinafter acquired, with respect to which such Stockholder has
the legal capacity to vote or to direct the vote of such Voting Securities, on
each matter submitted to a vote of the stockholders of the Company, (x) in the
same proportion as the votes cast by all holders of Voting Securities other than
the Stockholders and any affiliates and associates of the Company, with respect
to such matter, or, (y) in the event of a proposed change of control transaction
for the Company, in the manner recommended to the stockholders by

                                      A-89
<PAGE>   419

the Board of Directors of the Company provided that the Board of Directors,
prior to such recommendation, shall have received an opinion from a nationally
recognized investment banking firm to the effect that the transaction or the
consideration to be received by the unaffiliated holders of the Common Stock is
fair from a financial point of view to such stockholders; provided, further,
that in the absence of such opinion such Voting Securities shall be voted as
provided in clause (x) of this Section 1.2.

     Each Stockholder shall take such action as may be required so that all
Voting Securities with respect to which such Stockholder has the legal capacity
to vote or to direct the vote of such Voting Securities as provided for herein
shall be present in person or by proxy at all duly noticed and convened meetings
of holders of Voting Securities for the purpose of determining the presence of a
quorum at such meetings.

     1.3 No Voting Trusts.   No Stockholder shall, directly or indirectly,
deposit any Voting Securities in a voting trust or in any other manner, except
pursuant to this Agreement, subject any Voting Securities to any arrangement or
agreement with respect to the voting thereof.

     1.4 No Election Contests.   No Stockholder shall, directly or indirectly,
solicit proxies or become a "participant" in a "solicitation" in opposition to
the recommendation of the Company's Board of Directors with respect to any
matter, including, without limitation, any "election contest" relating to the
election of directors of the Company (as such terms are defined in Regulation
14A under the Exchange Act) or initiate, propose or otherwise solicit
stockholders of the Company for the approval of one or more stockholder
proposals at any time, or induce or attempt to induce any other person to
initiate any stockholder proposal; provided, however, that each Stockholder
shall vote any Voting Securities directly or indirectly beneficially owned by
such Stockholder in any "election contest" in accordance with the provisions of
the first paragraph of Section 1.2 hereof.

     1.5 No Syndications.   No Stockholder shall, directly or indirectly, join
or encourage the formation of a partnership, limited partnership, syndicate or
other "group," or otherwise act in concert with any other Person (except as
contemplated by Section 1.2 hereof) for the purpose of affecting or influencing
control of the Company or acquiring, holding, or disposing of Voting Securities.

     1.6 Disposition of Voting Securities.   No Stockholder shall, directly or
indirectly, offer, sell, assign, pledge, encumber or otherwise dispose of or
transfer in any manner any Voting Securities (or enter into agreements or
understandings with respect to the foregoing), if after such disposition, the
Person holding such Voting Securities would own 5% or more of any class or
Series of the Company's Voting Securities (or Voting Securities which are
convertible into or exercisable for shares which, after giving effect to such
exercise or conversion, would represent 5% or more of any class of the Company's
Voting Securities). Any offer, sale, assignment, pledge, encumbrance or other
disposition or transfer of Voting Securities not otherwise prohibited by this
Agreement shall only be effected, to the extent otherwise legally permissible,
in the following manners: (i) pursuant to a bona fide public offering of Voting
Securities (which may include a secondary distribution effected through the
facilities of any national securities
                                      A-90
<PAGE>   420

exchange on which the Voting Securities are listed); provided, however, that in
case of any such proposed public offering, each Stockholder selling pursuant to
such offering (the "Selling Stockholder") will use his/her/its best efforts (and
will instruct the managing underwriter of any such public offering or
broker-dealer to or through which such public offering is being made to use its
best efforts) to achieve a sufficiently broad public distribution of the
securities being offered (in light of the number of securities being offered),
with the intention that no person or related group of persons should purchase in
such public offering Voting Securities representing 5% or more of the securities
being offered; (ii) pursuant to an unsolicited open market sale or sales during
any three-month period involving, in the aggregate, Voting Securities
representing not more than 1% of the Total Voting Power, as defined in Section
5.4, (in accordance with the requirements as to the manner of sale set forth in
Rules 144(f), 144(g) and 145 and (g) of the Securities Act or any successor
rules or regulations permitting sales of unregistered or otherwise restricted
securities, whether or not such sale is subject to Rule 144, Rule 145 or such
successor rules or regulations) on any national securities exchange on which the
Voting Securities are listed; (iii) pursuant to a tender offer made by the
Company or any subsidiary of the Company or made by a third person to the
stockholders of the Company as to which the Company's Board of Directors has
recommended to the stockholders of the Company; (iv) pursuant to a privately-
negotiated transaction with a Person who is not a Stockholder; provided, that in
no case shall any such sale, transfer or other disposition under this clause
(iv) be made to such Person if, immediately after such transaction, such Person
(based upon the written representation of such Person, which as a condition
precedent to such sale, transfer or other disposition shall be delivered to such
Stockholder and to the Company prior to the consummation of such transaction),
together with its affiliates and associates would be the direct or indirect
beneficial or record owner of Voting Securities (when added to the Voting
Securities (if any) already beneficially owned by such Person and its affiliates
and associates) representing in excess of 5% of the Total Voting Power; (v)
pursuant to a will or the laws of descent and distribution; provided, that the
estate of a Stockholder shall be bound by the terms and conditions of this
Agreement and if, immediately after any distribution out of such estate, any
distributee, together with such distributee's affiliates and associates would
(other than solely as an income beneficiary of a trust) be the direct or
indirect beneficial or record owner of, or have the right to acquire, Voting
Securities (when added to the Voting Securities (if any) already owned by such
distributee and his/her affiliates and associates representing in excess of 5%
of the Total Voting Power, then such distributee shall, as a condition precedent
to receiving such shares of Voting Securities, agree to be bound by the terms
and conditions of a stockholder agreement having the same terms and conditions
as this Agreement; (vi) pursuant to a bequest or similar gift or transfer to any
Person who is not a Stockholder or; provided that if, immediately after delivery
of a bequest or similar gift or transfer, including, but not limited to, through
the creation of a trust, the recipient, together with such recipient's
affiliates and associates (including, as the case may be, the Stockholder making
such transfer), would (other than solely as an income beneficiary of a trust) be
the direct or indirect beneficial or record owner of, or have the right to
acquire, Voting Securities (when added to the Voting Securities (if any) already
owned

                                      A-91
<PAGE>   421

by such recipient and its affiliates and associates (including, as the case may
be, the Stockholder making such transfer)) representing in excess of 5% of the
Total Voting Power, then such recipient shall, as a condition precedent to
receiving such shares of Voting Securities, agree to be bound by the terms and
conditions of a stockholder agreement having the same terms and conditions as
this Agreement; or (vii) as a result of any pledge or hypothecation to a bona
fide financial institution to secure a bona fide loan, guaranty or other
financial accommodation or as a result of any foreclosure with respect thereto;
provided, however, that in connection with any transfer by a Stockholder of
Voting Securities pursuant to clauses (v) or (vi) of this Section 1.6 to a
trust, corporation or other entity and a Stockholder retains the authority, as
trustee or otherwise, to vote, acquire or dispose of, or to direct the voting,
acquisition or disposition of, Voting Securities to be held by such trust or
other entity, then as a condition precedent to the transfer of such shares of
Voting Securities to such trust or other entity, such Stockholder shall cause
such trust or other entity to be bound by the terms and conditions of a
stockholder agreement having the same or substantially the same terms and
conditions as this Agreement.

     Notwithstanding anything to the contrary contained herein, a Stockholder
shall not dispose of or otherwise transfer any Voting Securities in violation of
the provisions of Section 5 of the Securities Act.

     1.7 No Solicitation.   No Stockholder shall propose, solicit or participate
in any fashion, in any transaction relating to an acquisition of, a business
combination or similar transaction with, or a change of control of, the Company
or make or solicit or encourage any Person to make a tender offer for Voting
Securities.

     1.8 Legend on Voting Securities.   Each Stockholder agrees that each
certificate representing its Voting Securities shall bear the following legend,
which will remain thereon as long as such Voting Securities are subject to the
restrictions contained in this Agreement:

         The shares represented by this certificate are subject to the
     provisions of a Stockholder Agreement dated as of             , 2000, among
     the Company and certain Stockholders, and may not be sold or transferred
     except in accordance therewith. Copies of said Agreement are on file at the
     offices of the Secretary of the Company.

The Company may enter a stop transfer order with the transfer agent (or agents)
and the registrar (or registrars) of the Voting Securities against the transfer
of legended Voting Securities held by a Stockholder except in compliance with
the requirements of this Agreement. The Company agrees to remove promptly any
stop transfer order with respect to, and issue promptly either legended (if the
Voting Securities remain subject to the restrictions of this Agreement) or
unlegended certificates in substitution for, certificates for any such Voting
Securities that are no longer subject to or are to be transferred in compliance
with the restrictions contained in this Agreement. Without limiting the
generality of the foregoing, the Company shall promptly remove any stop transfer
order in effect with respect to such certificates, upon the delivery to the
Company of an opinion of counsel to a Stockholder, in form and substance
reasonably
                                      A-92
<PAGE>   422

satisfactory to the Company, that legended certificates representing Voting
Securities are no longer subject to this Agreement or that such Voting
Securities are being transferred in compliance with the provisions of Sections
1.6, and shall promptly issue unlegended certificates in substitution for such
legended certificates, except if such legended certificates are being
transferred pursuant to Section 1.6 to a transferee who shall be bound by the
terms and conditions of a Stockholder Agreement, in which event the Company may
issue legended certificates.

     Section 2. Representations and Warranties.

     2.1 Representations and Warranties of the Stockholders.   Each Stockholder
represents and warrants to the Company as follows:

     beneficial owner of the Shares of Common Stock set forth beside its name on
     Schedule A hereto (such Stockholder's "Shares") and will be the lawful
     owner of such Shares, free and clear of all liens, charges, encumbrances,
     voting agreements and commitments of every kind, other than this Agreement.
     Such Stockholder has full legal power, authority and right to vote all of
     such Stockholder's Shares in the manner required by this Agreement without
     the consent or approval of, or any other action on the part of, any other
     person or entity.

         (ii) The execution, delivery and performance by such Stockholder of
     this Agreement has been approved by all necessary action on the part of
     such Stockholder.

         (iii) This Agreement has been duly executed and delivered by such
     Stockholder and constitutes the valid and binding agreement of such
     Stockholder, enforceable against the Stockholder in accordance with its
     terms.

         (iv) The execution, delivery and performance of this Agreement by such
     Stockholder does not violate or breach, and will not give rise to any
     violation or breach of, any law, contract, instrument, arrangement or
     agreement by which such Stockholder is, or any of such Stockholder's Shares
     are, bound.

         (v) The execution, delivery and performance of this Agreement by such
     Stockholder does not create or give rise to any right in any other Person
     or entity (other than the Company) with respect to such Stockholder's
     Shares or any other Voting Securities.

     2.2 Representations and Warranties of the Company.   The Company represents

<PAGE>   423

         (iii) The execution and delivery of this Agreement by the Company does
     not violate or breach, and will not give rise to any violation or breach
     of, the charter or bylaws of the Company, or, except as will not materially
     impair its ability to effectuate, carry out or comply with all of the terms
     of this Agreement, any law, contract, instrument, arrangement or agreement
     by which the Company is bound.

     2.3 No Indirect Conduct.   No Stockholder shall engage in any conduct or
take any action through any agent or any entity acting in concert with such
Stockholder that the Stockholder has hereby agreed not to engage in or take.

     Section 3. Covenants of the Company.

     3.1 Registration Rights.   During the term and subject to all of the
provisions hereof (including, without limitation Section 1.6(vi)), the Company
agrees to provide registration rights to each Stockholder on the terms and
subject to the provisions set forth in Registration Rights Agreement attached as
Appendix I hereto.

     3.2 Access to Management.   The Company agrees that so long as a
Stockholder continues to hold 7.5% or more of any class of Voting Securities,
the Company shall provide such Stockholder with an opportunity on a regularly
scheduled basis to review with senior management of the Company, significant
issues facing the Company; provided, however, that such Stockholder shall agree
(i) to maintain the confidentiality of any non-public information disclosed to
such Stockholder in any such session, and (ii) if necessary, refrain from
engaging in any transaction involving the Company's securities (or any other
securities) while in possession of any material non-public information about the
Company disclosed to such Stockholder by the Company in the course of the
Company's complying with the provisions of this Section 3.2.

     Section 4. Term of Agreement.

     The term of this Agreement shall commence at the Effective Time and shall
terminate with respect to any given Stockholder (but only such Stockholder) when
such Stockholder ceases to hold at least 7.5% of the issued and outstanding
shares of Common Stock (as adjusted for any stock splits, stock dividends,
combinations, recapitalizations, reclassifications or other similar event)
unless the transaction or transactions which resulted in such Stockholder
ceasing to hold at least 7.5% of any Common Stock or Voting Securities shall
have violated the terms of this Agreement. For purposes hereof, ownership of
Common Stock or Voting Securities shall include record ownership of such
securities as well as beneficial ownership thereof within the meaning of Rule
13d-3 under the Securities Exchange Act of 1934, as amended.

     Section 5. Miscellaneous.

     5.1 Specific Performance.   The Company and each Stockholder acknowledge
and agree that irreparable damage would occur in the event any of the provisions
of this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the Company or a
Stockholder, as the case may be, shall be entitled to an injunction or
injunctions to prevent breaches of the provisions of this Agreement and to
enforce specifically, the terms and provisions hereof in any

                                      A-94
<PAGE>   424

court of the United States or any state thereof having jurisdiction, in addition
to any other remedy to which it may be entitled at law or equity.

     5.2 The Term "Company."   The term "Company" shall be deemed to include any
successor to the Company by way of merger, consolidation, sale of assets or
otherwise, except as the context otherwise requires, it being the intention
hereof that this Agreement shall continue to be binding on each Stockholder
notwithstanding such merger, consolidation, sale of assets or other succession,
unless the provisions of Section 4.2 of this Agreement shall otherwise provide.

     5.3 The Terms "Affiliate," Associate," "Beneficial Owner" "Entity," and
"Person." As used herein, the term "affiliate" shall have the meaning set forth
in Rule 12b-2 under the Exchange Act; the term "beneficial owner" (which shall
include "beneficially owned" or other similar phrasing as used herein) shall
have the meaning set forth in Section 13(d)(3) of the Securities Act; the term
"associate" shall mean (1) a corporation or organization (other than the Company
or a subsidiary of the Company) of which such Person (as defined herein) is an
officer or partner or is, directly or indirectly, the beneficial owner of 10
percent or more of any class of equity securities, (2) any trust or other estate
in which such Person has a substantial beneficial interest or as to which such
Person serves as trustee or in a similar capacity, and (3) any relative or
spouse of such Person, or any relative of such spouse, who has the same home as
such Person; and the term "Person" shall mean any individual, partnership,
corporation, joint venture, association, unincorporated organization, trust,
government or agency thereof, or any other entity.

     5.4 The Term "Total Voting Power."   The term "Total Voting Power," as used
in this Agreement, shall mean the aggregate voting power of all Voting
Securities outstanding at the time of any determination which at such time have
ordinary voting power to vote in the election of directors of the Company. In
determining Total Voting Power for purposes of this Agreement, the Stockholder
may conclusively rely on the most recent reports filed by the Company with the
SEC in which the number of Voting Securities outstanding is set forth or from
which Total Voting Power can reasonably be derived, it being understood that
each Stockholder shall not be considered to be in breach of this Agreement if
he/she has acted in good faith on the basis of a determination of Total Voting
Power as contemplated herein.

named hereunder shall be in writing (including wire, telex or similar writing)

     VOTING AGREEMENT, dated as of March 12, 2000 (the "Agreement"), by and
among CoreComm Limited, a Bermuda corporation ("Parent"), and the Persons listed
on Schedule A hereto (each, a "Shareholder" and, collectively, the
"Shareholders").

     WHEREAS, Voyager.net, Inc., a Delaware corporation (the "Company"), and
Parent propose to enter into an Agreement and Plan of Merger in the form
attached hereto as Exhibit A (as amended, the "Merger Agreement"), which
provides for, among other things, the merger of a wholly owned subsidiary of
Parent with and into the Company (the "Merger");

     WHEREAS, as of the date hereof, the Shareholders are holders of record or
Beneficially Own (as defined herein) shares of common stock, par value $.01 per
share ("Company Common Stock"), of the Company; and

     WHEREAS, as a condition to the willingness of Parent to enter into the
Merger Agreement, Parent has required that each Shareholder agree, and in order
to induce Parent to enter into the Merger Agreement, each Shareholder has
agreed, to enter into this Agreement with respect to all of the shares of
Company Common Stock now held of record or Beneficially Owned and which may
hereafter be acquired by such Shareholder (collectively, the "Shares").

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereto hereby agree as follows:

                                   ARTICLE I

                              CERTAIN DEFINITIONS

     Section 1.1 General.   Capitalized terms used and not defined herein have
the respective meanings ascribed to them in the Merger Agreement.

     Section 1.2 Beneficial Ownership.   For purposes of this Agreement,
"Beneficially Own" or "Beneficial Ownership" with respect to any securities
shall mean "beneficial ownership" of such securities (as determined pursuant to
Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), including pursuant to any agreement, arrangement or understanding,
whether or not in writing. Without duplicative counting of the same securities
by the same holder, securities Beneficially Owned by a Shareholder shall include
securities Beneficially Owned by all other Persons (as defined in the Merger
Agreement) with whom such Person would constitute a "group" within the meaning
of Section 13(d) of the Exchange Act other than parties to this Agreement.

                                   ARTICLE II

     Section 2.1 Voting Agreement.   Each of the Shareholders hereby irrevocably
and unconditionally agrees that during the term of this Agreement as specified
in Section 5.1,

                                      A-100
<PAGE>   430

at any meeting of the shareholders of the Company, however called, and in any
action by consent of the shareholders of the Company, each of the Shareholders
shall vote (or cause to be voted) the Shares held of record (to the extent such
Person also has the right to vote such Shares) or Beneficially Owned (to the
extent such Person also has the right to vote such Shares) by such Shareholder:

         (a) in favor of the Merger, the Merger Agreement (provided that the
     Merger Agreement shall not have been amended in a manner materially adverse
     to the interests of the Shareholders thereunder) and the transactions
     contemplated by the Merger Agreement. Each of the Shareholders acknowledges
     receipt and review of a copy of the Merger Agreement.

         (b) against any Business Combination (as defined below) other than the
     Merger. For purposes of this Agreement, "Business Combination" shall mean,
     whether effected in one transaction or a series of transactions, or (a) any
     merger, consolidation, reorganization or other business combination

     or more Persons including, without limitation, any joint venture, in
     violation of the Merger Agreement, or (b) the acquisition, directly or
     indirectly, by another Person of all or a substantial portion of the assets
     of, or of any right to all or a substantial portion of the revenues or
     income of, the Company by way of a negotiated purchase, lease, license,
     exchange, joint venture or other means, in violation of the Merger
     Agreement, or (c) the acquisition, directly or indirectly, by another
     Person of control of the Company through a proxy contest or otherwise, in
     violation of the Merger Agreement, or (d) the acquisition, directly or
     indirectly, by another Person of Voting Securities representing more than
     15% of the Total Voting Power of the Company.

each of them individually, its irrevocable proxy and attorney-in-fact (with full
power of substitution and resubstitution) to vote the Shares as indicated in
this Article II. Each Shareholder intends this proxy to be irrevocable and
coupled with an interest and will take such further action and execute such
other instruments as may be necessary to effectuate the intent of this proxy.

     Section 2.3 The Terms "Total Voting Power" and "Voting Securities".   The
term "Total Voting Power," as used in this Agreement, shall mean the aggregate
voting power of all Voting Securities outstanding at the time of any
determination which at such time have ordinary voting power to vote in the
election of directors of the Company. For the purposes of this Agreement,
"Voting Securities" means all securities of the Company, or any successor to the
Company, entitling the holder thereof to vote as a shareholder for any purpose
or under any circumstance or any securities convertible into or exchangeable for
under any circumstance such securities or any rights, warrants or options to
acquire (through purchase, exchange, conversion or otherwise) any such
securities under any circumstance.

Agreement or to consummate such transactions. This Agreement has been duly and
validly executed and delivered by such Shareholder and constitutes a legal,
valid and binding obligation of such Shareholder, enforceable against such
Shareholder in accordance with its terms, except to the extent enforceability

     (a) The execution and delivery of this Agreement by such Shareholder does
not, and the performance of this Agreement by such Shareholder shall not, (i)

or other entity, conflict with or violate the organizational documents of such
Shareholder, (ii) conflict with or violate any agreement, arrangement, law,
rule, regulation, order, judgment or decree to which such Shareholder is a party

constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of a lien
or encumbrance on any of the Shares held of record or Beneficially Owned by such
Shareholder pursuant to any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which such Shareholder is a party or by which such Shareholder (or the Shares
held of record or Beneficially Owned by such Shareholder) is bound or affected,
except, in the case of clauses (ii) and (iii) of this Section 3.2(a), for any
such conflicts, violations, breaches, defaults or other occurrences which would
not prevent or delay the performance by such Shareholder of its obligations
under this Agreement.

not, and the performance of this Agreement by such Shareholder shall not,
require any consent, approval, authorization or permit of, or filing with or
notification to, any governmental entity except for applicable requirements, if

Company may take any of the actions that are expressly permitted by Section 7.1
of Merger Agreement.

         (vii) the date the Merger Agreement is terminated, if such termination
     is by either Parent or the Company pursuant to Section 10.1(b)(i) of the
     Merger Agreement due to the failure to obtain the required approval of the
     stockholders of Parent, which approval is required to be obtained under
     Section 9.1(a) of the Merger Agreement; and

         (viii) 180 days after the date the Merger Agreement is terminated in
     accordance with its terms, other than as set forth in clauses (ii) through

acquires the right to vote any additional shares of Company Common Stock (any
such shares shall be referred to herein as "Additional Shares"), including,
without limitation, upon exercise of any option, warrant or right to acquire
shares of Company Common Stock or through any stock dividend or stock split, the
provisions of this Agreement applicable to the Shares shall be applicable to

irreparable damage would occur in the event any provision of this Agreement was
not performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or in equity.

     Section 5.4 Entire Agreement.   This Agreement constitutes the entire
agreement between Parent and the Shareholders with respect to the subject matter
hereof and supersedes all prior agreements and understandings, both written and
oral, between Parent and the Shareholders with respect to the subject matter
hereof.

     Section 5.5 Amendment and Waiver.   No alteration, waiver, amendment or
supplement of this Agreement shall be binding or effective unless the same is
set forth in an instrument in writing signed by the parties hereto. The waiver
or failure to insist upon strict compliance with any condition or provision
hereof shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other waiver or failure.

     Section 5.6 Severability.   If any term or other provision of this
Agreement is held to be invalid, illegal or unenforceable, all other conditions
and provisions of this Agreement shall nevertheless remain in full force and
effect so long as the economic or legal substance of this Agreement is not
affected in any manner materially adverse to any party. Upon such determination
that any term or other provision is invalid, illegal or incapable of being
enforced, the parties hereby shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible to the fullest extent permitted by applicable law in a mutually
acceptable manner in order that the terms of this Agreement remain as originally
contemplated.

     Section 5.7 Governing Law.   This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to
agreements made and to be performed entirely within such state.

irrevocably waives, to the fullest extent permitted by law, all rights to trial
by Jury in any action, proceeding or counterclaim (whether based on contract,
tort or otherwise) arising out of or relating to this Agreement or any of the
transactions contemplated hereby.

     Section 5.9 Counterparts.   This Agreement may be executed in one or more
counterparts, each of which shall be an original and all of which, when taken
together, shall constitute one and the same instrument.

                 RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

     RECAPITALIZATION AGREEMENT AND PLAN OF MERGER, dated as of March 9, 2000,
by and among ATX Telecommunications Services, Inc., a Delaware corporation
("ATX"), CoreComm Limited, a Bermuda corporation ("CoreComm"), Thomas Gravina
("Gravina"), Debra Buruchian ("Buruchian"), Michael Karp ("Karp") and The
Florence Karp Trust (the "Karp Trust" and, collectively with Gravina, Buruchian
and Karp, the "ATX Stockholders").

                                    RECITALS

     WHEREAS, the Boards of Directors of ATX, and CoreComm, respectively, deem
it advisable and in the best interests of ATX, CoreComm and their respective
stockholders that ATX and CoreComm combine in order to advance the long-term
business interests of ATX and CoreComm;

     WHEREAS, the combination of ATX and CoreComm shall be effected by the terms
of this Recapitalization Agreement and Plan of Merger (the "Agreement") through
the Merger (of CoreComm Merger Sub (as defined herein) and ATX Merger Sub (as
defined herein)) and the Recapitalization (each as defined herein) of ATX; and

     WHEREAS, for federal income tax purposes, it is intended that the Merger
and Recapitalization shall qualify as exchanges within the meaning of Section
351 of the Internal Revenue Code of 1986, as amended (the "Code") and as
reorganizations within the meaning of Section 368(a) of the Code.

     WHEREAS, the Boards of Directors of ATX and CoreComm have approved this
Agreement and each of the documents required to be executed in connection with
this Agreement to which it is a party.

     Accordingly, in consideration of the representations, warranties, covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereto agree as follows:

                                 I. THE MERGER

     1.1 The Formation of ATX Merger Sub, CoreComm Merger Sub and the Merger.

     (a) As promptly as practicable following the execution of this Agreement,
ATX shall cause to be organized for the sole purpose of effectuating the Merger
contemplated herein a corporation organized under the laws of the State of
Delaware ("ATX Merger Sub"). As promptly as practicable following the execution
of this Agreement, CoreComm shall cause to be organized for the sole purpose of
effecting the Domestication Merger (as defined in Section 1.1(d) below) and the
Merger contemplated herein, a corporation organized under the laws of the State
of Delaware ("CoreComm Merger Sub"). The respective certificates of
incorporation and Bylaws of each of ATX Merger Sub and CoreComm Merger Sub shall
be in such forms as shall be mutually determined by ATX and CoreComm as soon as
practicable following the execution of this Agreement and the authorized capital
stock of each of ATX Merger

                                       B-6
<PAGE>   445

Sub and CoreComm Merger Sub shall initially consist of 100 shares of common
stock, par value $0.01 per share. All of the outstanding shares of ATX Merger
Sub shall be issued to ATX at a price of $1.00 per share and all of the
outstanding shares of CoreComm Merger Sub shall be issued to CoreComm at a price
of $1.00 per share.

     (b) As promptly as practicable following the execution of this Agreement,
ATX (with respect to ATX Merger Sub) and CoreComm (with respect to CoreComm
Merger Sub) shall take all requisite action to designate the directors and
officers of ATX Merger Sub and CoreComm Merger Sub and take such steps as may be
necessary or appropriate to complete the organization of ATX Merger Sub and
CoreComm Merger Sub. ATX shall cause the directors of ATX Merger Sub to ratify
and approve this Agreement. CoreComm shall cause the directors of CoreComm
Merger Sub to ratify and approve this Agreement.

     (c) As promptly as practicable following the organization of ATX Merger
Sub, ATX, as the sole stockholder of ATX Merger Sub, shall cause ATX Merger Sub
to adopt this Agreement and to perform its obligations under this Agreement. As
promptly as practicable following the organization of CoreComm Merger Sub,
CoreComm, as the sole stockholder of CoreComm Merger Sub shall cause CoreComm
Merger Sub to adopt this Agreement and to perform its obligations under this
Agreement. As promptly as practicable after the organization of ATX Merger Sub
and CoreComm Merger Sub, the parties shall cause this Agreement to be amended to
add ATX Merger Sub and CoreComm Merger Sub as parties hereto. Such amendment
shall provide for the making by ATX Merger Sub of those representations and
warranties equivalent to those set forth in Article 3 hereof that apply to ATX
Merger Sub, and covenants and obligations equivalent to those set forth in
Article 5 hereof that apply to ATX Merger Sub, and ATX Merger Sub and CoreComm
Merger Sub shall each become a constituent corporation in the Merger.

     (d) Immediately prior to the Merger, CoreComm shall amalgamate and merge
with and into CoreComm Merger Sub (the "Domestication Merger"), subject to
compliance with applicable provisions of the Delaware General Corporation Law
(the "DGCL") and the laws of Bermuda. As a result of the Domestication Merger,
each issued and outstanding share of CoreComm Common Stock shall become and
represent one share of common stock, par value $.01 per share ("CoreComm Merger
Sub Common Stock"), of CoreComm Merger Sub, and the independent existence of
CoreComm shall cease. Prior to the consummation of the Domestication Merger,
CoreComm, as sole stockholder of CoreComm Merger Sub, shall adopt this
Agreement. Unless the context otherwise requires, all references in this
Agreement to CoreComm shall be deemed to mean CoreComm prior to the consummation
of the Domestication Merger and CoreComm Merger Sub following the consummation
of the Domestication Merger, and all references to CoreComm Common Stock shall
be deemed to mean the CoreComm Common Stock prior to the consummation of the
Domestication Merger and CoreComm Merger Sub Common Stock after the consummation
of the Domestication Merger.

<PAGE>   446

     (e) Subject to the provisions of this Agreement, a certificate of merger
(the "Certificate of Merger") in such form as is required by the relevant
provisions of the DGCL shall be duly prepared, executed and acknowledged by the
appropriate parties and thereafter delivered to the Secretary of State of the
State of Delaware for filing, as provided in the DGCL, on the Closing Date (as
defined in Section 2.1). The Merger shall become effective upon the filing of
the Certificate of Merger with the Secretary of State of the State of Delaware
(the "Effective Time").

     (f) At the Effective Time, the separate existence of ATX Merger Sub shall
cease and ATX Merger Sub shall be merged (the "Merger") with and into CoreComm
Merger Sub (ATX Merger Sub and CoreComm Merger Sub are sometimes referred to
herein as the "Constituent Corporations" and CoreComm Merger Sub is sometimes
referred to herein as the "Surviving Corporation"). The Certificate of
Incorporation of CoreComm Merger Sub as in effect immediately prior to the
Effective Time shall be the Certificate of Incorporation of the Surviving
Corporation until thereafter amended as provided by the DGCL, the Bylaws of
CoreComm Merger Sub as in effect immediately prior to the Effective Time shall
be the Bylaws of the Surviving Corporation until thereafter amended as provided
by the DGCL, the Certificate of Incorporation and such Bylaws.

     (g) At and after the Effective Time, the effect of the Merger shall be as
provided in the applicable provisions of the DGCL. Without limiting the
generality of the foregoing, and subject thereto, the Surviving Corporation
shall possess all the rights, privileges, powers and franchises of a public as
well as of a private nature, and be subject to all the restrictions,
disabilities and duties of each of the Constituent Corporations; and all and
singular rights, privileges, powers and franchises of each of the Constituent
Corporations, and all property, real, personal and mixed, and all debts due to
either of the Constituent Corporations on whatever account, as well as for stock
subscriptions and all other things in action or belonging to each of the
Constituent Corporations, shall be vested in the Surviving Corporation, and all
property, rights, privileges, powers and franchises, and all and every other
interest shall be thereafter the property of the Surviving Corporation as they
were of the Constituent Corporations, and the title to any real estate vested by
deed or otherwise, in either of the Constituent Corporations, shall not revert
or be in any way impaired; but all rights of creditors and all liens upon any
property of either of the Constituent Corporations shall be preserved
unimpaired, and all debts, liabilities and duties of the Constituent
Corporations shall thereafter attach to the Surviving Corporation, and may be
enforced against it to the same extent as if such debts and liabilities had been
incurred by it.

     1.2 The Recapitalization.

     (a) Simultaneously with the Merger, ATX shall recapitalize (the
"Recapitalization") by causing the ATX Stockholders to exchange, and the ATX
Stockholders agree to exchange, all of the issued and outstanding shares of
pre-Recapitalization ATX

                                       B-8
<PAGE>   447

common stock, par value $.01 per share ("ATX Common Stock") for the following
aggregate consideration:

         (i) That number of shares of ATX Common Stock equal to $500 million
     divided by the Base Stock Price. The "Base Stock Price" shall be equal to
     $40.328, subject to the Base Adjustments as defined below.

     The number of shares of ATX Common Stock to be received by the ATX
Stockholders in connection with the Recapitalization will be subject to a collar
mechanism as follows: in the event that the volume weighted average trading
price of CoreComm Common Stock for the ten trading days ending with the last
trading day prior to the Closing Date (the "Closing Stock Price") is greater
than the Collar Stock Price (as defined below), then the number of shares of ATX
Common Stock to be issued to the ATX Stockholders pursuant to the
Recapitalization will be adjusted such that the aggregate value (based on the
Closing Stock Price) of the ATX Common Stock received by the ATX Stockholders is
equal to the aggregate value (based on the Closing Stock Price) of ATX Common
Stock they would have been entitled to receive if the Closing Stock Price were
equal to the Collar Stock Price.

     The "Collar Stock Price" shall be the Base Stock Price multiplied by the
Collar Percentage. The Collar Percentage shall be equal to 115%, subject to the
following adjustments: If (1) the Closing has not occurred on or prior to July
15, 2000, (2) subsequent to the date of this Agreement, CoreComm has engaged in
a transaction (other than transactions contemplated by this Agreement, which
shall not be deemed to include the potential transaction referred to in Section
5.18 or any transaction which would result in a Base Adjustment) (a "CoreComm
Transaction") that would (x) require the approval of the stockholders of
CoreComm or, (y) require CoreComm to include the information relating to such
transaction in the pro forma financial statements (the "Pro Formas") that are
required to be contained in the Registration Statement or (z) require CoreComm
to amend or restate the Pro Formas in any material manner, and (3) all
conditions to Closing have been satisfied (or waived by the party entitled to
waive such condition) or are capable of being satisfied on such date with
reasonable best efforts, other than the conditions set forth in Sections 6.10
and/or 6.11, and the failure of either such condition to be satisfied is the
direct result of a CoreComm Transaction, then, commencing on the later to occur
of (i) July 16, 2000 and (ii) the first business day after which the
circumstances set forth in clause (3) are present (such later date being the
"Trigger Day") the Collar Percentage shall be increased as follows: 2.5
percentage points on the Trigger Day, and an additional five percentage points
per each 31 day period (a "Monthly Period") (on a pro rata basis, based on the
actual number of elapsed days in such Monthly Period at the Closing Date)
beginning on the sixteenth calendar day following the Trigger Day. An example of
this calculation is set forth on Exhibit J.

     The "Base Adjustments" shall be as follows: (i) if, after the date of this
Agreement and on or prior to the Closing Date the outstanding shares of CoreComm
Common Stock shall be changed into a different number of shares by reason of any
reclassification, recapitalization, stock split, reverse stock split,
combination or exchange

                                       B-9
<PAGE>   448

of shares, or any dividend payable in CoreComm Common Stock shall be declared
thereon with a record date within such period, or any similar event shall occur,
the Base Stock Price shall be adjusted accordingly to provide to the ATX
Stockholders the same economic effect as contemplated by this Agreement prior to
such reclassification, recapitalization, stock split, reverse stock split,
combination, exchange, dividend or similar event; and (ii) if, after the date of
this Agreement and on or prior to the Closing Date, CoreComm shall distribute to
all holders of CoreComm Common Stock shares of capital stock of CoreComm other
than CoreComm Common Stock, evidences of indebtedness or other assets (other
than cash dividends out of current or retained earnings), or shall distribute to
substantially all holders of Common Stock rights or warrants to subscribe for
securities (other than those referred to in subsection (i) above), then in each
such case the Base Stock Price shall be multiplied by a fraction of which the
numerator shall be the Current Market Price (as defined below) of the CoreComm
Common Stock on the record date less the then fair market value (as determined
by the CoreComm Board of Directors, whose determination shall be conclusive
evidence of such fair market value (absent manifest error) and described in a
board resolution) of the portion of the assets so distributed or of such
subscription rights or warrants applicable to one share of CoreComm Common Stock
and of which the denominator shall be the Current Market Price of the CoreComm
Common Stock. The "Current Market Price" shall mean the volume weighted average
trading price of CoreComm Common Stock for the ten prior trading days. CoreComm
may only effect a distribution described under (ii) above, if such distribution
does not include operating assets that are required to maintain the current
operating businesses of CoreComm, Inc. (a subsidiary of CoreComm), other than
the local multipoint distribution service licenses and related assets.

     (ii) 250,000 shares of ATX Series 3% Senior Convertible Exchangeable
Preferred Stock, par value $.01 per share ("ATX Convertible Preferred Stock"),
with such rights and preferences as set forth in the term sheet attached hereto
as Exhibit A setting forth the terms and conditions of the ATX Convertible
Preferred Stock; and

     (iii) $150 million in cash (the "Cash Consideration") (subject to certain
adjustments set forth herein) (collectively with the ATX Common Stock and the
ATX Convertible Preferred Stock, the "Exchange Consideration"); provided,
however, that in the event CoreComm has not completed a debt or equity financing
(including a public or private sale of equity securities or an institutional
debt financing) prior to the Closing Date, at CoreComm's election, the aggregate
amount of Cash Consideration to be paid by CoreComm to the ATX Stockholders may
be reduced by up to $70 million and such portion of the Cash Consideration shall
be paid through the issuance of short term senior notes with such terms and
conditions as set forth in the term sheet attached hereto as Exhibit B.

     (b) ATX shall prepare as of a date not more than five (5) business days
prior to the Closing Date, an unaudited consolidated balance sheet (estimated as
of the Closing Date) and unaudited statements of income and cash flows of ATX
for the period from the ATX Balance Sheet Date to the date of such statements
(the "Pre-Closing Financial Statements") from the GAAP Audited Financials and
the books and records of ATX in

                                      B-10
<PAGE>   449

accordance with GAAP (applied on a consistent basis using the same accounting
methods, policies, practices, principles and procedures with consistent
classifications, judgments and estimation methodologies used in preparation of
the GAAP Audited Financials) and shall set forth the Working Capital ("Estimated
Closing Working Capital"), the ATX Debt (the "Estimated Closing ATX Debt") and
the estimated capital expenditures made by ATX during such period (the
"Estimated Closing Capital Expenditures"). To the extent ATX intends to make
distributions at Closing as permitted by Section 1.2(j), such intended
distributions shall be included in the Pre-Closing Financial Statements on a
pro-forma basis. ATX shall provide a copy of the Pre-Closing Financial
Statements to CoreComm within three (3) days of its completion.

     In the event that the Pre-Closing Financial Statements reflect that the
Estimated Closing Working Capital is less than zero (such deficiency, the
"Working Capital Shortfall"), then the Exchange Consideration shall be reduced
(subject to the calculation of the Final Closing Financial Statements) by an
amount equal to the excess of zero over the Estimated Closing Working Capital.
If the Pre-Closing Financial Statements reflect that the Estimated Closing
Working Capital is greater than zero (such excess, the "Working Capital Excess")
then the Exchange Consideration shall be increased (subject to the calculation
of the Final Closing Financial Statements) by an amount equal to the amount of
the Working Capital Excess. The Working Capital Shortfall or Working Capital
Excess, as applicable, shall be the "Pre-Closing Working Capital Adjustment."

     In the event that the Pre-Closing Financial Statements reflect that
Estimated Closing ATX Debt is greater than zero, then the Exchange Consideration
shall be reduced (subject to the calculation of the Final Closing Financial
Statements) by an amount equal to the Estimated Closing ATX Debt.

     In the event that the Pre-Closing Financial Statements reflect that the
Capital Expenditure Adjustment, as calculated using the Estimated Closing
Capital Expenditures from the Pre-Closing Financial Statements, is greater than
zero (such amount, the "Pre-Closing Capital Expenditure Adjustment"), then the
Exchange Consideration shall be reduced (subject to a calculation of the final
Closing Financial Statements) by an amount equal to the Pre-Closing Capital
Expenditure Adjustment.

     (c) Within ninety (90) days after the Closing Date (the "Closing Financial
Statements Delivery Date"), ATX shall cause to be prepared and delivered to the
Stockholder Representative (as defined below) a proposed unaudited balance sheet
and proposed unaudited statements of income and cash flows (the "Proposed
Closing Financial Statements") prepared in accordance with GAAP (applied on a
consistent basis using the same accounting methods, policies, practices,
principles and procedures with consistent classifications, judgments and
estimation methodologies that were used in preparation of the GAAP Audited
Financials) setting forth the Working Capital of ATX and ATX Debt as of the
Closing Date and Capital Expenditures of ATX for the period from the ATX Balance
Sheet Date through the Closing Date. For purposes of this Section 1.2, the
Stockholder Representative shall mean BDO Seidman, LLP.

                                      B-11
<PAGE>   450

     (d) The Stockholder Representative shall have a period of thirty (30) days
(the "Review Period") from the date on which ATX delivers the Proposed Closing
Financial Statements to the Stockholder Representative pursuant to Section
1.2(c), to review the Proposed Closing Financial Statements. If, prior to the
expiration of the Review Period, the Stockholder Representative does not deliver
a Dispute Notice (as defined below) to ATX, the unaudited balance sheet and
unaudited statements of income and cash flows included in the Proposed Closing
Financial Statements shall be deemed to be final and binding upon ATX and the
ATX Stockholders for purposes of determining the Working Capital of ATX and the
ATX Debt as of the Closing Date and the Capital Expenditures of ATX for the
period from the ATX Balance Sheet Date through the Closing Date for purposes of
this Agreement. The unaudited balance sheet and unaudited statements of income
and cash flows included in the Proposed Closing Financial Statements shall not
become final and binding at the end of the Review Period if, prior to the
expiration of the Review Period, the Stockholder Representative delivers a
written notice to ATX (the "Dispute Notice") setting forth in reasonable detail
the disagreements that the Stockholder Representative has with the unaudited
balance sheet and/or either of the unaudited statements of income and cash flows
included in the Proposed Closing Financial Statements and the effect which such
disagreements would have on the calculation of any of the Working Capital of ATX
and ATX Debt as of the Closing Date or Capital Expenditures of ATX for the
period from the ATX Balance Sheet Date through the Closing Date. If the
Stockholder Representative delivers a Dispute Notice prior to the end of the
Review Period, the representatives of ATX and the Stockholder Representative
shall have a ten (10) day period (the "Settlement Period") from the date of the
delivery of the Dispute Notice to attempt to resolve any dispute set forth in
the Dispute Notice and to agree upon an unaudited balance sheet and unaudited
statements of income and cash flows which shall be binding on ATX and the ATX
Stockholder for purposes of this Agreement and to agree upon the Working Capital
of ATX and ATX Debt as of the Closing Date and the Capital Expenditures of ATX
for the period from the ATX Balance Sheet Date through the Closing Date. If the
Stockholder Representative and ATX have not arrived at an agreement during the
Settlement Period then, at any time following the termination of the Settlement
Period, either the Stockholder Representative or ATX may submit the issue in
dispute to the Philadelphia, Pennsylvania office of PricewaterhouseCoopers LLP
(the "Accountant") for resolution in accordance with this Section. In resolving
any disputed item, the Accountant (i) shall be bound by the provisions of this
Section 1.2, (ii) may not assign a value to any item greater than the greatest
value for such item claimed by either party or less than the smallest value for
such item claimed by either party, (iii) shall make its determination based
solely on information submitted by the parties and not by independent review and
(iv) shall be instructed to issue a report containing its resolution of the
disputed issue or issues (the "Accountant's Report") within thirty (30) days
following submission of the dispute. The Accountant's Report shall be delivered
by the Accountant to ATX and the Stockholder Representative, and shall be final
and binding on ATX and the ATX Stockholders for purposes of this Agreement. The
fees charged by the Accountant shall be paid by ATX.

                                      B-12
<PAGE>   451

     (e) During the period of any dispute within the contemplation of this
Section 1.2, the ATX Stockholders, the Stockholder Representative and their
representatives (including counsel and accountants) shall have reasonable access
during normal business hours to all books, records, employees, offices and other
facilities and properties of the Surviving Corporation to the extent required to
complete their review of the Closing Financial Statements and shall be permitted
to review the working papers (subject to the execution of customary waivers,
releases and indemnifications), if any, of ATX or its auditor relating to the
Closing; provided that any such access shall not unreasonably interfere with the
day-to-day operations of ATX and shall be limited to those items related to the
assessment of the Closing Financial Statements and matters related thereto. ATX
and CoreComm or their auditors shall cooperate with the ATX Stockholders and
other representatives of the ATX Stockholders in facilitating such review.

     (f) In the event that the Final Closing Financial Statements reflect that
the Working Capital of ATX as of the Closing Date is less than the Applicable
Amount (such deficiency, the "Final Working Capital Shortfall"), then an amount
equal to the excess of the Applicable Amount over the Final Working Capital
Shortfall shall be paid to ATX from the Escrow (defined below) as provided in
Subsection 1.2(i) (the "Final Shortfall"); provided, however, that the Final
Shortfall shall be adjusted to reflect any adjustments to the Closing Exchange
Consideration previously made due to a Pre-Closing Working Capital Adjustment.
If the Final Closing Balance Sheet reflects that the Working Capital of ATX as
of the Closing Date is greater than the Applicable Amount (a "Final Working
Capital Excess") then an amount equal to the excess of the Final Working Capital
Excess over the amount of Working Capital generated subsequent to July 31, 2000
shall be delivered to the ATX Stockholders by ATX as provided in Subsection
1.2(i); provided, however, that the Final Working Capital Excess (and any
related amounts to be paid) shall be adjusted to reflect any adjustments to the
Closing Exchange Consideration previously made due to a Pre-Closing Working
Capital Adjustment. As used herein, the "Applicable Amount" means $2,000,000, if
the Closing occurs on or prior to July 31, 2000 and zero if the Closing occurs
after July 31, 2000.

     (g) In the event that the Final Closing Financial Statements reflect that
the ATX Debt is greater than zero (such amount the "Final ATX Debt"), then an
amount equal to the Final ATX Debt shall be paid to ATX from the Escrow as
provided in Subsection 1.2(i); provided, however, that the Final ATX Debt shall
be adjusted to reflect any adjustments to the Closing Exchange Consideration
previously made due to any Estimated Closing ATX Debt.

     (h) In the event that the Final Closing Financial Statements reflect that
the Capital Expenditure Adjustment, as calculated utilizing the Capital
Expenditures as set forth on the Final Closing Financial Statements, is greater
than zero (the "Final Capital Expenditure Adjustment"), then the amount equal to
the Final Capital Expenditure Adjustment shall be paid to ATX from the Escrow as
provided in Subsection 1.2(i); provided, however, that the Final Capital
Expenditure Adjustment shall be adjusted to

                                      B-13
<PAGE>   452

reflect adjustments to the Closing Exchange Consideration previously made due to
a Pre-Closing Capital Expenditure Adjustment.

     (i) Upon the Recapitalization, an aggregate of 1.1111% of all shares of ATX
Common Stock, ATX Convertible Preferred Stock and Cash Consideration (provided
that if any portion of the Cash Consideration is to be payable in Short Term
Senior Notes, the Short Term Senior Notes shall be delivered prior to the Cash
Consideration) comprising the Exchange Consideration shall be deposited in
escrow (the "Escrow") pursuant to an escrow agreement among ATX, CoreComm, each
ATX Stockholder and an escrow agent selected by such parties (the "Escrow
Agreement"). In the event of any reduction in the Exchange Consideration
requiring a repayment to ATX under Subsections (f) through (h) above, such
repayment shall be made pro rata from the ATX Common Stock, ATX Convertible
Preferred Stock and cash in the Escrow, for purposes of which the ATX Common
Stock shall be valued at the closing price for ATX Common Stock on the trading
day immediately preceding the day on which the repayment of such share to ATX is
effected. Any amounts payable by ATX under Subsection (f) as additional Exchange
Consideration shall be in shares of ATX Common Stock based on the same valuation
as set forth in the preceding sentence subject to the right of any ATX
Stockholders to elect to receive such additional Exchange Consideration in cash.

     (j) From the ATX Balance Sheet Date through the Closing Date, ATX shall be
permitted to:

         (i) make such cash distributions and payments to the ATX Stockholders:
     (x) in order to satisfy any debt obligation of ATX to the ATX
     Stockholder(s) (including affiliates thereof); (y) in order to return any
     capital to the ATX Stockholders (including the amount of any positive
     capital account balances respecting the ATX Partnerships) (as hereinafter
     defined); and (z) of any undistributed profits computed in accordance with
     GAAP of ATX or the ATX Partnership through the Closing Date; provided that
     if there is insufficient cash on hand to make such distributions and
     payments, the amounts shall be payable by ATX on the business day next
     following the Closing Date and the payment of such amounts shall be deemed
     to have been made on the business day prior to the Closing Date for
     purposes of the adjustments set forth in this Section 1.2; or (ii) cancel
     or eliminate any indebtedness owed by any ATX Stockholders to ATX.

     (k) The following terms, whenever used herein, shall have the following
meanings for all purposes of this Agreement:

         "ATX Balance Sheet Date" means December 31, 1999.

         "ATX Capital Expenditure Obligation" means the obligation of ATX and
     the ATX Partnerships to make Capital Expenditures from the period
     commencing January 1, 2000 through the Closing Date in the amount and for
     those categories of items set forth on Section 1.2 of the ATX Disclosure
     Schedule.

                                      B-14
<PAGE>   453

("CoreComm Common Stock"):

         (a) Each issued and outstanding share of ATX Merger Sub Common Stock
     shall be converted into the right to receive one (1) share of CoreComm
     Common Stock.

         (b) All shares of CoreComm Common Stock that are owned by CoreComm as
     treasury stock or by any Subsidiary of CoreComm shall be canceled and
     retired and shall cease to exist and no consideration shall be delivered in
     exchange therefor. As used in this Agreement, the word "Subsidiary" means,

     Sec-

                                      B-15
<PAGE>   454

     tion 1.3(b) and shares to be issued under Section 1.3(a)) shall be
     converted into the right to receive one (1) (the "Merger Ratio") fully paid
     and nonassessable shares of ATX Common Stock. All such shares of CoreComm
     Common Stock, when so converted, shall no longer be outstanding and shall
     automatically be canceled and retired and shall cease to exist, and each
     holder of a certificate representing any such shares shall cease to have
     any rights with respect thereto, except the right to receive the shares of
     ATX Common Stock and any cash in lieu of fractional shares of ATX Common
     Stock to be issued or paid in consideration therefor upon the surrender of
     such certificate in accordance with Section 1.4.

     1.4 Exchange of Certificates.   The procedures for exchanging outstanding
shares of CoreComm Common Stock for ATX Common Stock pursuant to the Merger
shall be as follows:

         (a) As of the Effective Time, ATX shall deposit with an exchange agent
     selected by CoreComm and reasonably acceptable to ATX (the "Exchange
     Agent"), for the benefit of the holders of shares of CoreComm Common Stock,
     certificates representing the shares of ATX Common Stock and cash (such
     shares of ATX Common Stock together with any dividends or distributions
     with respect thereto, together with such cash, being hereinafter referred
     to as the "Exchange Fund") issuable pursuant to Section 1.3 in exchange for
     outstanding shares of CoreComm Common Stock.

         (b) Promptly after the Effective Time, the Exchange Agent shall mail to
     each holder of record of a certificate or certificates which immediately
     prior to the Effective Time represented outstanding shares of CoreComm
     Common Stock (each a "Certificate" and, collectively, the "Certificates")
     whose shares were converted pursuant to Section 1.4 into the right to
     receive shares of ATX Common Stock (i) a letter of transmittal (which shall
     specify that delivery shall be effected, and risk of loss and title to the
     Certificates shall pass, only upon delivery of the Certificates to the
     Exchange Agent and shall be in such form and have such other provisions as
     ATX and CoreComm may reasonably specify) and (ii) instructions for use in
     effecting the surrender of the Certificates in exchange for certificates
     representing shares of ATX Common Stock. Upon surrender of a Certificate
     for cancellation to the Exchange Agent, together with such letter of
     transmittal, duly executed, the holder of such Certificate shall be
     entitled to receive in exchange therefor a certificate representing that
     number of whole shares of ATX Common Stock which such holder has the right
     to receive pursuant to the provisions of this Article 1, and the
     Certificate so surrendered shall immediately be canceled. In the event of a
     transfer of ownership of CoreComm Common Stock which is not registered in
     the transfer records of CoreComm, a certificate representing the proper
     number of shares of ATX Common Stock may be issued to a transferee if the
     Certificate representing such CoreComm Common Stock is presented to the
     Exchange Agent, accompanied by all documents required to evidence and
     effect such transfer and by evidence that any applicable stock transfer
     taxes have been paid. Until surrendered as contemplated by this Section
     1.4, each Certificate shall

                                      B-16
<PAGE>   455

     be deemed at any time after the Effective Time to represent only the right
     to receive upon such surrender the certificate representing shares of ATX
     Common Stock and cash in lieu of any fractional share as contemplated by
     this Section 1.4. All shares of ATX Common Stock issued upon the surrender
     for or exchange of Certificates in accordance with the terms of this
     Agreement, shall be deemed to have been issued in full satisfaction of all
     rights pertaining to the CoreComm Common Stock shares formerly represented
     by such Certificates. The instructions for effecting the surrender of the
     Certificates shall set forth procedures that must be taken by the holder of
     any Certificate that has been lost, destroyed or stolen. It shall be a
     condition to the right of such holder to receive a certificate representing
     shares of ATX Common Stock that the Exchange Agent shall have received,
     along with the letter of transmittal, a duly executed lost certificate
     affidavit, including an agreement to indemnify ATX, signed exactly as the
     name or names of the registered holder or holders appeared on the books of
     CoreComm immediately prior to the Effective Time, together with a customary
     bond and such other documents as ATX or the Exchange Agent may reasonably
     require in connection therewith.

         (c) No dividends or other distributions declared or made after the
     Effective Time with respect to ATX Common Stock with a record date after
     the Effective Time shall be paid to the holder of any unsurrendered
     Certificate with respect to the shares of ATX Common Stock represented
     thereby and no cash payment in lieu of fractional shares shall be paid to
     any such holder pursuant to subsection (e) below until the holder of such
     Certificate shall surrender such Certificate. Subject to the effect of
     applicable laws, following surrender of any such Certificate, there shall
     be paid to the holder of the certificates representing whole shares of ATX
     Common Stock issued in exchange therefor, without interest, (i) at the time
     of such surrender, the amount of any cash payable in lieu of a fractional
     share of ATX Common Stock to which such holder is entitled pursuant to
     subsection (e) below and the amount of dividends or other distributions
     with a record date after the Effective Time previously paid with respect to
     such whole shares of ATX Common Stock, and (ii) at the appropriate payment
     date, the amount of dividends or other distributions with a record date
     after the Effective Time but prior to surrender and a payment date
     subsequent to surrender payable with respect to such whole shares of ATX
     Common Stock.

         (d) All shares of ATX Common Stock issued upon the surrender for
     exchange of shares of CoreComm Common Stock in accordance with the terms
     hereof (including any cash paid pursuant to subsection (c) or (e) of this
     Section 1.4) shall be deemed to have been issued in full satisfaction of
     all rights pertaining to such shares of CoreComm Common Stock, subject,
     however, to the Surviving Corporation's obligation to pay any dividends or
     make any other distributions with a record date prior to the Effective Time
     which may have been declared or made by CoreComm on such shares of CoreComm
     Common Stock in accordance with the terms of this Agreement on or prior to
     the date hereof and which remain unpaid at the Effective Time, and there
     shall be no further registration of transfers on the stock transfer books
     of the Surviving Corporation of the shares of CoreComm

                                      B-17
<PAGE>   456

     Common Stock which were outstanding immediately prior to the Effective
     Time. If, after the Effective Time, Certificates are presented to the
     Surviving Corporation for any reason, they shall be canceled and exchanged
     as provided in this Section 1.4.

         (e) No certificate or scrip representing fractional shares of ATX
     Common Stock shall be issued upon the surrender for exchange of
     Certificates, and such fractional share interests will not entitle the
     owner thereof to vote or to exercise any rights of a stockholder of ATX.
     Notwithstanding any other provision of this Agreement, each holder of
     shares of CoreComm Common Stock exchanged pursuant to the Merger who would
     otherwise have been entitled to receive a fraction of a share of ATX Common
     Stock (after taking into account all Certificates delivered by such holder)
     shall receive, in lieu thereof, cash (without interest) in an amount equal
     to such fractional part of a share of ATX Common Stock multiplied by the
     last reported sale price of ATX Common Stock, as reported on The Nasdaq
     National Market, on the first trading day after the Effective Time.

         (f) Any portion of the Exchange Fund which remains undistributed to the
     stockholders of CoreComm for one year after the Effective Time shall be
     delivered to ATX, and any former stockholders of CoreComm who have not
     previously complied with this Section 1.4 shall thereafter look only to ATX
     for payment of their claim for ATX Common Stock, any cash in lieu of
     fractional shares of ATX Common Stock, and any dividends or distributions
     with respect to CoreComm Common Stock or ATX Common Stock.

         (g) Neither CoreComm nor ATX shall be liable to any former holder of
     shares of CoreComm Common Stock or current holder of ATX Common Stock, as
     the case may be, for such shares (or dividends or distributions with
     respect thereto) delivered to a public official as required by any
     applicable abandoned property, escheat or similar law.

     1.5 Directors and Officers of Surviving Corporation.   The initial
directors of the Surviving Corporation shall be the directors of CoreComm
immediately prior to the Merger, each to hold office in accordance with the
Certificate of Incorporation and Bylaws of the Surviving Corporation, and the
initial officers of the Surviving Corporation shall be the officers of CoreComm
immediately prior to the Merger, in each case until their respective successors
are duly elected or appointed.

     1.6 Directors and Officers of ATX.   At Closing, the directors of ATX shall
be the directors of CoreComm immediately prior to the Merger, each to hold
office in accordance with the Certificate of Incorporation and Bylaws of ATX,
and the initial officers of ATX shall be the officers of CoreComm immediately
prior to the Merger, in each case until their respective successors are duly
elected or appointed.

use of the property affected thereby and all material leases, subleases,
licenses or other agreements pursuant to which ATX leases real or personal
property, are in good standing, valid and effective in accordance with their
respective terms, and there is not, under any such lease, any existing default
(or event which with notice or lapse of time, or both, would constitute a
default).

     3.10 Compliance with Law; Licenses.

     (a) Except as set forth on Section 3.10(a) of the ATX Disclosure Schedule,
the business of ATX (including, without limitation, the ATX Partnerships prior

laws (whether statutory or otherwise), rules, regulations, orders, ordinances,
judgments, decrees, writs and injunctions of all federal, state, local or
foreign governmental authorities including subdivisions thereof (collectively,
"Laws"), including all Laws relating to the safe conduct of ATX's business,
environmental protection and conservation, antitrust, taxes, consumer
protection, currency exchange, telecommunications, equal opportunity, health,

variances, exemptions, authorizations, operating certificates, orders and
approvals of all Governmental Entities (collectively, "Licenses") that are
required for it to own, lease and operate its properties and conduct its

not, individually or in the aggregate, have a Material Adverse Effect. Except as

                                      B-26
<PAGE>   465

set forth on Section 3.10(a) of the ATX Disclosure Schedule, there has occurred
no default under or violation of any such License, except for such violations or
defaults that would not, individually or in the aggregate, have a Material
Adverse Effect.

     (b) Since December 31, 1998, ATX has filed with the applicable PUCs (as
defined below) or the FCC, as the case may be, all forms, statements, reports
and documents (including exhibits, annexes and any amendments thereto) required
to be filed by them, and each such filing complied in all material respects with
all applicable laws, rules, and regulations, other than such failures to file
and non-compliance that would, individually or in the aggregate, have a Material
Adverse Effect on it or prevent or impair its ability to consummate the
transactions contemplated by this Agreement.

     (c) ATX has all permits, licenses, franchises, consents, registrations,
certificates, variances, exemptions, orders and other governmental or regulatory
authorizations, consents and approvals, necessary to conduct its business as
presently conducted and for the ownership, lease or operation of property that
it now owns or leases, except for those the absence of which would not,
individually or in the aggregate, have a Material Adverse Effect on it or
prevent, delay or impair its ability to consummate the transactions contemplated
by this Agreement (collectively, "Permits"). All such Permits are listed on
Section 3.10(c) of the ATX Disclosure Schedule and are in full force and effect;
no material violations are or have been recorded in respect of any Permit and no
proceeding is pending or threatened to revoke or limit any Permit. No action by
ATX or CoreComm or any other person is required in order that all Permits will
remain in full force or effect following the consummations of the transactions
contemplated by this Agreement. All Permits are valid and in full force and
effect, and ATX has duly performed and is in compliance in all material respects
with all of its obligations under such Permits.

     (d) Except as set forth on Section 3.10(d) of the ATX Disclosure Schedule,
ATX has validly and properly obtained the necessary Permits from the appropriate
governmental authority in each such jurisdiction, including, without limitation,
state public service and public utilities commissions ("State PUCs") (the "State
Permits") and municipal authorities (the "Municipal Permits") and holds all
Permits issued by the FCC (the "FCC Permits") that are required for the conduct
of its business as it has been and is presently conducted, and for the holding
of its assets. All of the FCC Permits, the State Permits and the Municipal
Permits (collectively the "Communications Permits") are set forth in Section
3.10(d) of the ATX Disclosure Schedule.

     (e) Each of the Communications Permits was duly issued and is valid and in
full force and effect and each of the Communications Permits has not been
modified, canceled, revoked, or conditioned in any adverse manner. Each of the
Communications Permits has not been sold, conveyed, pledged, assigned or
transferred to any other party, and no other party has any present or future
right to acquire use of them.

     (f) Except as set forth on Section 3.10(d)(i) of the ATX Disclosure
Schedule, ATX has complied with and is in compliance with all regulations and
laws applicable to its operations under the Communications Permits, except where
any such failure would not individually or in the aggregate have a Material
Adverse Effect. ATX is in
                                      B-27
<PAGE>   466

compliance with, and its businesses have operated in compliance with, the
Communications Act of 1934, as amended, FCC regulations, or any applicable state
laws or regulations, and has filed all tariffs, registrations and reports and
paid all required fees, including any renewal applications, required by the
Communications Act of 1934, as amended, or any applicable state regulations and
has complied with the terms of each such tariff or regulation, except where any
such failure would not individually or in the aggregate have a Material Adverse
Effect. There is no action, suit, investigation or other proceeding pending or,
to ATX's knowledge, threatened against ATX which might materially adversely
affect the Communications Permits, or the assignment of the Communications
Permits to CoreComm. No event has occurred with respect to the Communications
Permits which, after notice or lapse of time, or both, would permit revocation
or termination thereof, or would result in any impairment of the rights of the
holder of the Communications Permits or the imposition of a forfeiture against
ATX or any subsequent holder of the Communications Permits with respect to the
operation of the facilities authorized thereby.

     (g) ATX has delivered to CoreComm correct and complete copies of (a) ATX's
Communications Permits and the applications related thereto together with any
pending applications filed by ATX for new or modified facilities related to the
purchased business, and (b) all other Permits and any tariffs filed by ATX
relating to the purchased business, and any applications for additional or
modified Permits to the purchased business.

     3.11 Taxes.

     (a) ATX has timely filed or will file (including any applicable extension
periods) all material tax reports, returns and forms required to be filed by it
on or before the Closing Date in the manner provided by applicable federal,
state, local or foreign tax laws. Copies of all material tax returns for ATX in
respect of all years not barred by the statute of limitations have been
delivered by ATX to CoreComm and all such returns are listed on Section 3.11 of
the ATX Disclosure Schedule.

     (b) With respect to each of ATX's tax returns that has been examined or
audited by the Internal Revenue Service or a state, local or foreign taxing
authority (collectively, an "Authority"), which returns are identified on the
ATX Disclosure Schedule, all deficiencies asserted as a result of such
examinations or audits have been fully paid, adequately provided for or are
being contested in good faith, except where the failure to be fully paid,
adequately provided for or contested would not have a Material Adverse Effect
individually or in the aggregate. There are no outstanding agreements or waivers
extending the statutory period of limitation applicable to any federal, state,
local or foreign tax return for any period.

     (c) Except as set forth on Section 3.11 of the ATX Disclosure Schedule, ATX

such payments which have not had, individually or in the aggregate, a Material
Adverse Effect. Except as set forth on Section 3.11 of the ATX Disclosure
Schedule, no tax liens have been filed on any property or assets of ATX and no
claims are being asserted with respect to any Taxes which, individually or in
the aggregate, would have a Material Adverse Effect.

be obtained prior to Closing (which such consents and approvals are listed on
Section 3.12 of the ATX Disclosure Schedule and which have heretofore been
provided to CoreComm for review) and consents and approvals the failure of which
to obtain would not, individually or in the aggregate, have a Material Adverse
Effect or prevent or impede or delay the consummation of the transactions
contemplated hereby, ATX is not required to obtain, transfer or cause to be
transferred any consent, approval or License of, or make any declaration, filing
or registration with, any third party or any governmental or regulatory
authority in connection with (a) the execution and delivery by ATX of this
Agreement or any agreement contemplated hereby, or (b) the consummation by ATX
of the transactions contemplated hereby or thereby except for those required
under (i) the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
and the rules and regulations promulgated thereunder (the "HSR Act") (ii) the

reasonable for the business and assets of ATX. All such insurance policies are
listed on Section 3.14 of the ATX Disclosure Schedule.

     3.15 Certain Interests.   Neither ATX nor any officer, director or

other proprietary rights and all Scheduled Intellectual Property (collectively,
the "Intellectual Property"), free and clear of any Liens except for Liens which
would not have, individually or in the aggregate, a Material Adverse Effect.
None of ATX's Intellectual Property is subject to any pending or, to the
knowledge of ATX, threatened, challenge or reversion except for challenges or
reversions which would not have, individually or in the aggregate, a Material
Adverse Effect. To the knowledge of ATX, the conduct of the business of ATX as
now being conducted, and the use of ATX's Intellectual Property in the conduct
of such business, do not infringe or otherwise conflict with any trademarks,
patents, registrations, or other intellectual property or proprietary rights of
others, nor, has any claim been made that the conduct of such business as now
being conducted infringes or otherwise is covered by the intellectual property
of a third party other than claims which would not have, individually or in the
aggregate, a Material Adverse Effect. To the knowledge of ATX, none of its
Intellectual Property is currently being infringed by a third party.

regulations and no transaction prohibited by any applicable statute or
regulation, including Section 406 of ERISA or Section 4975 of the Code, has
occurred with respect to any Benefit Plan that would individually or in the
aggregate be reasonably likely to result in material liability to ATX; (ii) each
Benefit Plan which is intended to be qualified within the meaning of Section
401(a) of the Code is so qualified and has received a favorable determination
letter as to its qualification, and nothing has occurred, whether by action or
failure to act, that could reasonably be expected to cause the loss of such
qualification; (iii) no event has occurred and no condition exists that would
subject ATX or any of its subsidiaries either directly or by reason of their
affiliation with any member of their "Controlled Group" (defined as any
organization which is a member of a controlled group of organizations within the
meaning of Code sections 414(b), (c), (m) or (o)), to any tax, fine, lien,
penalty or other liability imposed by ERISA, the Code or other applicable laws,
rules and regulations; and (v) there are no actions, suits or claims (other than
routine claims for benefits) pending or threatened against the Benefit Plans
and, no facts exist which could give rise to any such actions, suits, or claims
that would be reasonably likely to result in material liability to the Company
with respect to the Benefit Plans.

     (e) No Benefit Plan or other agreement or arrangement exists that, as a
result of the transactions contemplated by this Agreement, could result in the
payment to any present or former employee of ATX of any money or other property
or accelerate the time of, or increase the amount of payment to which such
person may otherwise be entitled or to provide any other rights or benefits to
any present or former employee of ATX or any other person, whether or not such
payment would constitute a parachute payment within the meaning of Section 280G
of the Code. Except as set forth in the ATX Disclosure Schedule, no employee or
former employee of ATX will become entitled to any bonus, retirement, severance,
job security or similar benefit or enhancement of such benefit (including
acceleration of vesting or exercise of an incentive award) as a result of the
transactions contemplated hereby.

post-employment or post-retirement health or medical or life insurance benefits
for retired, former or current employees of ATX nor maintains any deferred
compensation plan.

     (g) No Benefit Plan or other agreement or arrangement exists that, as a
result of the transactions contemplated by this Agreement (including the ATX
Merger), could result in the payment by ATX to any present or former employee of
University City Housing ("UCH") of any money or other property or accelerate the
time of, or increase the amount of payment by ATX to which such person may
otherwise be entitled, or could result in the requirement that ATX provide any
other rights or benefits to any present or former employee of UCH or any other
person (as a result of such person's status as an employee of UCH), including
but not limited to, any severance payment, whether or not such payment would
constitute a parachute payment within the meaning of Section 280G of the Code.
No employee or former employee of UCH (as a result of such person's status as an
employee of UCH) is or will become entitled to any bonus, retirement, severance,
job security or similar benefit or enhancement of such benefit (including
acceleration of vesting or exercise of an incentive award) from ATX as a result
of the transactions contemplated hereby.

     3.18 Labor Matters.   None of the individuals employed by ATX or any of its
subsidiaries or affiliates is represented by a union. ATX has made no collective
bargaining agreements with respect to any current or former employees of ATX or
any of its subsidiaries or affiliates. No labor strike, picketing, work
stoppage, work slowdown, soliciting, petition for a representation election or
civil action, or other labor dispute has, within the last five years, occurred
or, to ATX's knowledge, has been threatened with respect to ATX.

federal, state and local laws, rules and regulations relating to pollution or
protection of the environment (collectively, the "Environmental Laws") required
for the operation of its business except for Licenses the lack of which would
not have a Material Adverse Effect individually or in the aggregate. ATX is in
compliance in all material respects with all terms and conditions of such
Licenses and all Environmental Laws and has not received any notice alleging
non-compliance. There is no civil, criminal or administrative action, suit,
demand, claim, investigation, proceeding, notice or demand letter pending or, to

advisor or other firm or Person is or will be entitled to any broker's or

     3.21 Accounting and Tax Matters.   Neither ATX nor any of its Affiliates

Recapitalization from constituting transactions qualifying as exchanges under
Section 351 of the Code and a merger under Section 368(a) of the Code.

     3.22 Registration Statement; Proxy Statement/Prospectus.   The information

time the Registration Statement is declared effective by the SEC under the
Securities Act of 1933, as amended, contain any untrue statement of a material
fact or omit to state any material fact required to be stated in the
Registration Statement or necessary in order to make the statements in the
Registration Statement, in light of the circumstances under which they were

inclusion in the proxy statement/prospectus (the "Proxy Statement") to be sent

to consider this Agreement and the Merger (collectively, the "Stockholders'
Meeting") shall not, on the date the Proxy Statement is first mailed to
stockholders of CoreComm at the time of the Stockholders' Meeting and at the
Effective Time, contain any statement which, at such time and in light of the
circumstances under which it was made, is false or misleading with respect to
any material fact, or omit to state any material fact necessary in order to make
the statements made in the Proxy Statement not false or misleading, or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Stockholders'
Meeting which has become false or misleading. If at any time prior to the
Effective Time any event relating to ATX or any of its Affiliates, officers or
directors should be discovered by ATX which should be set forth in an amendment
to the Registration Statement or a supplement to the Proxy Statement, ATX shall
promptly inform CoreComm.

     3.23 Non-Competition Agreements.   Neither ATX nor any officer, director,
or key employee of ATX, is a party to any agreement, other than with ATX or its
predecessors, that purports to restrict or prohibit it, directly or indirectly,
from engaging in any business involving telecommunications or any other material
business currently engaged in by ATX, or to the knowledge of ATX, by CoreComm or
any corporations affiliated with CoreComm.

     3.24 Customers.   No single customer of ATX generates greater than 2% of

an untrue statement of a material fact or omits to state a material fact
required to be stated herein or necessary to make the statements made, in the
context in which made, not materially false or misleading. There is no fact,
event, circumstance or condition that ATX has not disclosed to CoreComm in
writing that has or would have, insofar as ATX can now foresee, a Material
Adverse Effect on ATX or the ability of ATX to perform this Agreement or the
Escrow Agreement.

     3.27 NO OTHER REPRESENTATIONS OR WARRANTIES.   EXCEPT AS SPECIFICALLY AND
EXPRESSLY SET FORTH IN THIS ARTICLE 3, (I) ATX MAKES NO REPRESENTATION OR
WARRANTY, EXPRESS OR IMPLIED, RELATING TO ATX, OR THE ASSETS OR BUSINESS OF ATX,
INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION OR WARRANTY AS TO VALUE,
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR FOR ORDINARY PURPOSES, OR
ANY OTHER MATTER AND (II) ATX MAKES NO, AND HEREBY DISCLAIMS ANY, OTHER

                 IV. REPRESENTATIONS AND WARRANTIES OF CORECOMM

     Except as set forth in the CoreComm Disclosure Schedule delivered by
CoreComm to ATX prior to the execution of this Agreement (the "CoreComm
Disclosure Schedule") (each section of which qualifies the correspondingly
numbered representation and warranty or covenant to the extent specified
therein) or in the CoreComm SEC Reports, CoreComm represents and warrants to ATX
as follows:

     4.1 Organization, Etc.   CoreComm is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation. CoreComm has the power and authority to conduct its business as
it is currently being conducted and to own, operate and lease the property and
assets that it now owns and leases. CoreComm is duly qualified or licensed and
in good standing to do business and has paid all relevant franchise and similar
taxes in each jurisdiction in which the nature of its business or the ownership
or leasing of its properties makes such qualification or license necessary,
except where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect. The copies of the Memorandum of
Association (the "CoreComm Memorandum of Association") and Bylaws (the "CoreComm
Bylaws") of CoreComm, as previously delivered to ATX by CoreComm, are complete
and correct copies of such instruments as currently in effect.

     4.2 Authorization.   CoreComm has all power and authority necessary to
execute and deliver this Agreement, to perform its obligations under this
Agreement and consummate the transactions contemplated by this Agreement. The
execution and delivery of this Agreement, the performance of CoreComm's
obligations hereunder and the consummation of the transactions contemplated
hereby has been duly authorized by CoreComm and no corporate proceedings on the
part of CoreComm are necessary to authorize this Agreement or to consummate such
transactions. This Agreement has been duly executed and delivered by CoreComm
and constitutes a valid and binding obligation

                                      B-35
<PAGE>   474

of CoreComm, enforceable against CoreComm in accordance with its terms, except
as such enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and similar laws relating to or affecting creditors rights generally,
or by general equity principles (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

     4.3 Capitalization.

     (a) The authorized capital stock of CoreComm consists of 75,000,000 shares
of common stock par value $.01 per share, and 1,000,000 shares of preferred
stock, par value $.01 per share. As of March 6, 2000, (i) 39,213,036 shares of
CoreComm Common Stock were issued and outstanding, all of which are validly
issued, fully paid and nonassessable and no shares of preferred stock were
issued and outstanding, and (ii) no shares of CoreComm Common Stock are held in
the treasury of CoreComm. Section 4.3 of the CoreComm Disclosure Schedule shows,
as of March 6, 2000, the number of shares of CoreComm Common Stock reserved for
future issuance pursuant to (i) stock options granted and outstanding as of the
date hereof, the plans under which such options were granted and award
agreements pursuant to which "non-plan" options were granted (collectively, the
"CoreComm Stock Plans"), (ii) the conversion of CoreComm's issued and
outstanding 6% convertible subordinated notes due 2006; and (iii) the exercise
of outstanding warrants. As of the date hereof, no other shares of CoreComm
Common Stock are issued and outstanding. All shares of CoreComm Common Stock
subject to issuance as specified above are duly authorized and, upon issuance on
the terms and conditions specified in the instruments pursuant to which they are
issuable, shall be validly issued, fully paid and nonassessable. There are no
obligations, contingent or otherwise, of CoreComm to repurchase, redeem or
otherwise acquire any shares of CoreComm Common Stock.

     (b) Except as reserved for future grants of options under the CoreComm
Stock Plans and as set forth on Section 4.3 of the CoreComm Disclosure Schedule,
(i) there are no equity securities of any class of CoreComm, or any security
exchangeable into or exercisable for such equity securities, issued, reserved
for issuance or outstanding; (ii) there are no options, warrants, equity
securities, calls, rights, commitments or agreements of any character to which
CoreComm is a party or by which it is bound obligating CoreComm to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
equity securities of CoreComm or obligating to grant, extend, accelerate the
vesting of or enter into any such option, warrant, equity security, call, right,
commitment or agreement; and (iii) there are no voting trusts, proxies or other
voting agreements or understandings with respect to the shares of equity
securities of CoreComm.

     4.4 No Violation.   Except as set forth on Section 4.4 of the CoreComm
Disclosure Schedule, neither the execution or delivery of this Agreement or any
agreement contemplated hereby by CoreComm, nor the performance by CoreComm of
the transactions contemplated hereby or thereby violates, conflicts with,

with notice or lapse of time or both, would constitute a default) under, gives
others any right of termination,

termination, amendment, cancellation or revocation of, or accelerates the
performance required by, or causes the acceleration of the maturity of any
liability or obligation pursuant to, or results in the creation or imposition of
any Lien upon any of the property or assets of CoreComm under (a) the CoreComm
Memorandum of Association or the CoreComm Bylaws or (b) except as individually
or in the aggregate would not have a Material Adverse Effect on any Law or any
Contract to which CoreComm is a party or by which CoreComm or its assets or
properties is or may be bound or affected.

     4.5 SEC Filings; Financial Statements.

     (a) CoreComm has timely filed all forms, reports and documents filed or
required to be filed by CoreComm with the SEC since January 1, 1999
(collectively, the "CoreComm SEC Reports") and has made the CoreComm SEC Reports
available to ATX. The CoreComm SEC Reports (i) at the time filed, complied in
all material respects with the applicable requirements of the Securities Act of
1933, as amended (the "Securities Act") and the Securities Exchange Act of 1934
(the "Exchange Act"), as the case may be, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated in such
CoreComm SEC Reports or necessary in order to make the statements in such
CoreComm SEC Reports, in the light of the circumstances under which they were
made, not misleading. CoreComm does not know of any fact, event or circumstance
that has occurred since the date of the last CoreComm SEC Report, or that now
exists, that (i) would have been required to be disclosed in a CoreComm SEC
Report if it had occurred prior to the date thereof, or (ii) that has had or
would have a Material Adverse Effect individually or in the aggregate.

     (b) Each of the consolidated financial statements (including, in each case,
any related notes) contained in the CoreComm SEC Reports complied as to form in
all material respects with the applicable published rules and regulations of the
SEC with respect thereto, was prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes to such financial statements
or, in the case of unaudited statements, in conformity with the requirements of
Form 10-Q under the Exchange Act) and fairly presented in all material respects
the consolidated financial position of CoreComm as of the dates and the
consolidated results of its operations and cash flows for the periods indicated,
except that the unaudited interim financial statements were or are subject to
normal and recurring year-end adjustments which were not or are not expected to
be material in amount. The CoreComm SEC Reports contain a balance sheet as of
September 30, 1999 which shall be referred to as the "CoreComm Balance Sheet".
September 30, 1999 shall be referred to as the "CoreComm Balance Sheet Date."

     4.6 Absence of Certain Changes.   Except as disclosed in the CoreComm SEC
Reports or in the CoreComm Disclosure Schedule, since the CoreComm Balance Sheet

                                      B-37
<PAGE>   476

Material Adverse Effect to CoreComm, individually or in the aggregate.

     4.7 Consents and Approvals.   Except for consents and approvals that will
be obtained prior to Closing and except for those consents and approvals with
regard to ATX's Communication Permits that are listed in Sections 3.10(d) and
3.12 of the ATX Disclosure Schedule (the "ATX Communications Consents") (which
consents and approvals other than the ATX Communications Consents are listed in
Section 4.7 of the CoreComm Disclosure Schedule and which have heretofore been
provided to ATX for review) and consents and approvals the failure of which to
obtain would not, individually or in the aggregate, have a Material Adverse
Effect or prevent or impede or delay the consummation of the transactions
contemplated hereby, CoreComm is not required to obtain, transfer or cause to be
transferred any consent, approval or License of, or make any declaration, filing
or registration with, any third party or any governmental or regulatory
authority in connection with (a) the execution and delivery by CoreComm of this
Agreement or any agreement contemplated hereby, or (b) the consummation by
CoreComm of the transactions contemplated hereby or thereby except for those
required under (i) the HSR Act, (ii) the Communications Act, (iii) the rules and
regulations of any PUC and local, state and foreign Government Entities
identified in the CoreComm Disclosure Schedule pursuant to applicable Utilities
Laws and (iv) the antitrust or other competition laws of any jurisdiction.

     4.8 Brokers or Finders.   No agent, broker, investment banker, financial
advisor or other firm or Person is or will be entitled to any broker's or
finder's fees or any similar commission or fee in connection with the
transaction contemplated by this Agreement, based upon arrangements made by or
on behalf of CoreComm, except Goldman, Sachs & Co., whose fees and expenses will
be paid by CoreComm.

     4.9 Accounting and Tax Matters.   Neither CoreComm nor any of its
Affiliates has taken or agreed to take any action which would prevent the
Mergers and the Recapitalization from constituting transactions qualifying as
exchanges under Section 351 of the Code and a merger under Section 368(a) of the
Code.

     4.10 Registration Statement; Proxy Statement/Prospectus.   The information
supplied or to be supplied by CoreComm or its Affiliates for inclusion in or
incorporation by reference in the Registration Statement shall not at the time
the Registration Statement is declared effective by the SEC under the Securities
Act, contain any untrue statement of a material fact or omit to state any
material fact required to be stated in the Registration Statement or necessary
in order to make the statements in the Registration Statement, in light of the
circumstances under which they were made, not misleading. The information
supplied or to be supplied by CoreComm for inclusion in the Proxy Statement
shall not, on the date the Proxy Statement is first mailed to stockholders of
CoreComm, at the time of the Stockholders' Meeting and at the Effective Time,

fact, or omit to state any material fact necessary in order to make the
statements made in the Proxy Statement not false or misleading, or omit to state
any material fact necessary to correct any

proxies for the Stockholders' Meeting which has become false or misleading. If
at any time prior to the Effective Time any event relating to CoreComm or any of
its Affiliates, officers or directors should be discovered by CoreComm which

Sachs & Co., dated March 9, 2000, that the transactions contemplated herein are
fair, from a financial point of view, based on information available as of the

EXPRESSLY SET FORTH IN THIS ARTICLE 4, (I) CORECOMM MAKES NO REPRESENTATION OR

     (a) As promptly as practicable after the execution of this Agreement, ATX
and CoreComm shall jointly prepare and file with the SEC the Proxy Statement and

     (c) In furtherance and not in limitation of the covenants of the parties
contained in this Section 5.7, if any administrative or judicial action or
proceeding, including any proceeding by a private party, is instituted (or
threatened to be instituted) challenging the transaction contemplated by this
Agreement as violative of any Regulatory Law, each of the parties hereto shall
cooperate in all respects with each other and contest and resist any such action
or proceeding and use its respective reasonable best efforts to have vacated,
lifted, reversed or overturned any decree, judgment, injunction or other order,
whether temporary, preliminary or permanent, that is in effect and that
prohibits, prevents or restricts consummation of the transaction contemplated by
this Agreement.

     (d) If any objections are asserted with respect to the transaction
contemplated hereby under any Regulatory Law or if any suit is instituted by any
Governmental Entity (including any foreign governmental entity) or any private
party challenging the transaction contemplated hereby as violative of any
Regulatory Law, each of the parties hereto shall use its reasonable best efforts
to resolve (through litigation, settlement or otherwise as CoreComm and ATX
shall reasonably determine) any such objections or challenge as such
Governmental Entity or private party may have to such transaction under such
Regulatory Law so as to permit consummation of the transaction contemplated by
this Agreement.

     (e) Each party hereto shall consult with, and utilize reasonable best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable (including using its best
efforts to provide all appropriate and necessary assistance to the other parties
hereto) with respect to the obtaining of all permits, consents, approvals and
authorizations of all third parties and Governmental Entities necessary or
advisable in order to consummate the transaction contemplated by this Agreement
and each party will keep the other party apprized of the status of matters
relating to completion of the transaction contemplated hereby.

     (f) Nothing in this Section 5.7 shall require CoreComm or ATX to sell, hold
separate or otherwise dispose of or conduct its business in a specified manner,
or permit the sale, holding separate or other disposition of, any of its assets
or the conduct of its business in a specified manner, or agree to payments or
modifications to contractual arrangements, whether as a condition to obtaining
any approval from a Governmental Entity or any permits, consents, approvals or
authorization of any other Person or for any other reason, if in CoreComm's or
ATX's sole judgment, as the case may be, such sale, holding separate or other
disposition of, or the conduct of its business in a specified manner or
agreement or modification, would reasonably be expected to materially diminish
the value of the transaction contemplated hereby to CoreComm or ATX, as the case
may be.

     (g) CoreComm shall have the right to have its designated representatives,
as provided to ATX from time to time (the "Designated CoreComm
Representatives"), present within normal business hours and without material
disruption to the business of ATX for consultation at ATX's principal offices
from the date hereof until the Closing Date. Such Designated CoreComm
Representatives shall have the right to review and become familiar with the
conduct of the business of ATX and shall be available to be

                                      B-44
<PAGE>   483

consulted and shall have authority on behalf of CoreComm in regard to
consultation in regard to Material Decisions (as defined below in this Section
5.7(g)). CoreComm shall take all reasonable actions necessary to ensure that its
Designated CoreComm Representatives will be readily available during normal
business hours. Without written notice to and favorable consultation (which
shall not be unreasonably withheld, delayed or conditioned with respect to time
or content) with the Designated CoreComm Representatives, ATX shall not take any
action involving any Material Decision. "Material Decision" shall mean, for
purposes of this Agreement, any of the following to the extent the same may
affect the assets, the obligations or the business of ATX following the date
hereof: (i) any entering into, termination or material amendment of, or waiver
of any ATX's rights in respect of, any material contracts; (ii) any purchase
order in excess of $100,000 in any instance to be delivered, or the payment for
which shall become due, after the Closing Date; (iii) the acceptance of any
material customer contract that deviates from the terms and conditions of
current pricing policies; (iv) any action to respond to any material customer or
regulatory complaint outside of the ordinary course of business; (v) any general
communication with customers related to the business or to the Merger; or (vi) a
material change in pricing, promotional, marketing or any other decision that
would affect any of ATX's customary profit margins.

     5.8 Public Announcements.   CoreComm and ATX shall consult with each other
before issuing any press release or otherwise making any public statement with
respect to this Agreement or the transaction contemplated hereby and shall not
issue any press release or make any such public statement without the prior
consent of the other party, which consent shall not be unreasonably withheld or
delayed except as may be required by applicable law or any requirement of any
stock exchange on which the stock of any party is listed.

     5.9 Effect of Due Diligence.   In connection with CoreComm's investigation
of the business of ATX, CoreComm may have received from or on behalf of ATX
certain projections, including projected statements of operating revenues and
income from operations of ATX. CoreComm acknowledges that there are
uncertainties inherent in attempting to make such estimates, projections and
other forecasts and plans, that CoreComm is familiar with such uncertainties,
that CoreComm is taking full responsibility for making its own evaluation of the
adequacy and accuracy of all estimates, projections and other forecasts and
plans so furnished to it (including the reasonableness of the assumptions
underlying such estimates, projections and forecasts), and that CoreComm shall
have no claim against ATX, or any of its Affiliates with respect thereto.
Accordingly, ATX makes no representation or warranty with respect to such
estimates, projections and other forecasts and plans (including the
reasonableness of the assumptions underlying such estimates, projections and
forecasts).

certified by BDO Seidman, LLP, and shall fairly present the consolidated
financial position of ATX and/or the ATX Partnerships at such dates and the
consolidated results of operations of the ATX Partnerships and their
subsidiaries for such respective periods, in each case in accordance with
generally accepted accounting principles consistently applied for the periods
covered thereby. (The foregoing consolidated financial statements of ATX and the

Closing Date.

     5.12 Stock Plans and Options.   CoreComm currently intends to implement a
stock option plan under which award grants may be made to post-Effective Time
employees of ATX and its subsidiaries, and that such post-Effective Time
employees shall include persons who prior to the Effective Time were employees
of ATX or its subsidiaries as well as of CoreComm or its subsidiaries; it being
understood that (i) nothing set forth herein shall be deemed to grant to any
specific employee of post-Effective Time ATX or its subsidiaries any right to
receive an option grant under any such plan, and (ii) the decision as to whether
or not any such plan shall be implemented, the terms of any such
                                      B-46
<PAGE>   485

stock option plan, and the terms of any grant made thereunder, shall be within
the discretion of post-Effective Time ATX, its board of directors, and any
committee of such board which may administer such plan.

     5.13 Access and Investigations.   Prior to the Closing Date, ATX agrees

including Paul, Weiss, Rifkind, Wharton & Garrison, and Ernst & Young LLP
(collectively, their "Representatives"), to make such investigation of the
properties, businesses and operations of ATX, and such examination of the books,
records and financial condition of ATX, as it wishes. Any such investigation and
examination shall be conducted at a reasonable time, upon reasonable advance
notice and under reasonable circumstances and ATX shall cooperate fully therein;
provided, however, that no such investigation or examination shall interfere
with the day-to-day operations of ATX. No investigation by CoreComm shall
diminish or obviate any of the representations, warranties, covenants or
agreements of ATX contained in this Agreement. In order that CoreComm may have
full opportunity to make such physical, business, accounting and legal review,
examination or investigation as it may wish of the affairs of ATX, ATX shall
make available to the Representatives during such period all such information
and copies of documents concerning the affairs of ATX as the Representatives may
reasonably request, and shall permit the Representatives access to the
properties of ATX in all parts thereof.

     5.14 Communications Licenses and Authorizations.   ATX shall obtain and
maintain in full force and effect all Permits, and any renewals thereof, from
the FCC and any appropriate State PUC and any municipal authority, and make all
filings and reports and pay all fees reasonably necessary or required for the
continued operation of its business, as and when such Permits, filings or
reports are necessary or required, other than any Permits, filings or reports
which would not, individually or in the aggregate, have a Material Adverse
Effect.

     5.15 FCC/State PUC Applications.

     (a) As promptly as practicable after the execution and delivery of this
Agreement, ATX shall prepare and deliver to CoreComm ATX's completed portion of

CoreComm shall have terminated this Agreement pursuant to Section 8.1, CoreComm
and ATX shall jointly request one or more extensions of the consummation period
of such grant. No party hereto shall knowingly take, or fail to take, any action
if the intent or reasonably anticipated consequence of such action or failure to
act is, or would be, to cause the FCC or State PUCs not to

                                      B-47
<PAGE>   486

grant approval of the FCC/State PUC Applications or materially delay either such

PUC Applications in good faith and with due diligence before the FCC and the
State PUCs, and in connection therewith shall take such action or actions as may
be necessary or reasonably required in connection with the FCC/State PUC
Applications, including furnishing to the FCC and the State PUCs any documents,

and the transaction contemplated by this Agreement shall be terminated, without
further action or obligation on the part of either party except as set forth in

                              IX. INDEMNIFICATION

     9.1 Indemnification by ATX Stockholders.   Subject to the limitations set
forth in this Article 9, and as an inducement to prompt CoreComm to enter into
this Agreement (without which such inducement CoreComm would not have entered
into this

                                      B-56
<PAGE>   495

Agreement), each of the ATX Stockholders hereby agree, jointly and severally, to
indemnify and hold harmless ATX from and after the Closing against and with
respect to any and all claims, demands, losses, costs, expenses, obligations,
liabilities, damages, recoveries, and deficiencies, including interest,
penalties, and reasonable fees and expenses of attorneys, experts, personnel and
consultants incurred by the Indemnified Party (as defined herein) (including in
any action or proceeding between the Indemnifying Party (as defined herein) and
the Indemnified Party or between the Indemnified Party and any third party or
otherwise) (together referred to as "ATX Losses") resulting from (i) any breach
of a representation, warranty, covenant, or agreement made by ATX, ATX Merger
Sub, or any of the ATX Stockholders, in this Agreement, the ATX Disclosure
Schedules or any other certificate or document delivered by ATX, ATX Merger Sub
or any of the ATX Stockholders to CoreComm pursuant to this Agreement each of
which representation, warranty, covenant or agreement shall be considered
without regard to any materiality or Material Adverse Effect qualification
therein for purposes of determining whether a breach has occurred, and any and
all demands, claims, actions, suits or proceedings, assessments, judgments,
costs and legal and other expenses incident to the foregoing, and (ii) the
failure of ATX to have either applied for or obtained any necessary regulatory
authorization or approval from any state public utilities commission or
comparable entity (regardless of whether or not such failure is disclosed in the
ATX Disclosure Schedule) in any state in which ATX had in excess of $25,000 of
revenues from intra-state operations in calendar year 1999.

     9.2 Procedures for Indemnification.

     (a) Promptly after receipt by a party (the "Indemnified Party") of notice
of the commencement of any action by a person not a party to this Agreement
involving the subject matter of the foregoing indemnity provisions other than
with respect to Taxes (a "Third Party Suit"), such Indemnified Party shall, if a
claim thereof is to be made against another party hereto (the "Indemnifying
Party") pursuant to the provisions of Section 9.1, promptly notify such
Indemnifying Party of the commencement thereof; but the omission to so notify
such Indemnifying Party will not relieve it from any liability which it may have
to the Indemnified Party to the extent the Indemnifying Party was not prejudiced
by such omission.

     (b) The Indemnifying Party shall have ten (10) days from receipt of such
notice to notify the Indemnified Party whether or not it disputes its liability
to the Indemnified Party with respect to such Third Party Suit and whether or
not it desires, at its sole cost and expense, to defend such Third Party Suit.
If the Indemnifying Party shall so notify the Indemnified Party that it desires
to defend against such Third Party Suit, the Indemnifying Party shall have the
right to defend against such Third Party Suit (unless (i) the Indemnifying Party
is also a party to such Proceeding and the Indemnified Party determines in good
faith that joint representation would be inappropriate, or (ii) the Indemnifying
Party fails to provide reasonable assurance to the Indemnified Party of its
financial capacity to defend such Proceeding and provide indemnification with
respect to such Proceeding), with counsel reasonably satisfactory to such
Indemnified Party, by

                                      B-57
<PAGE>   496

appropriate proceedings which shall be promptly settled or prosecuted by the
Indemnifying Party, so long as it diligently conducts such defenses, to a final
conclusion such that a (i) it will be conclusively established for purposes of
this Agreement that the claims made in that Proceeding are within the scope of
and subject to indemnification; (ii) no compromise or settlement of such claims
may be effected by the Indemnifying Party without the Indemnified Party's
consent unless (A) there is no finding or admission of any violation of Laws or
any violation of the rights of any Person and no effect on any other claims that
may be made against the Indemnified Party, and (B) the sole relief provided is
monetary damages that are paid in full by the Indemnifying Party; and (iii) the
Indemnified Party will have no liability with respect to any compromise or
settlement of such claims effected without its consent and the Indemnified Party
shall receive a full release. The Indemnified Party may elect to participate in
any such contest at its own cost and expense; provided, however, that the
control of such contest shall rest primarily with the Indemnifying Party.

     (c) Notwithstanding the foregoing (i) if the defendants in any action
include both the Indemnified Party and the Indemnifying Party and the
Indemnified Party shall have reasonably concluded that there may be legal
defenses available to it which are different from or additional to those
available to the Indemnifying Party, or if there is a conflict of interest which
would prevent counsel for the Indemnifying Party from also representing the
Indemnified Party, the Indemnified Party shall have the right to select separate
counsel to participate in the defense of such Third Party Suit on behalf of such
Indemnified Party, at the cost of the Indemnified Party; and (ii) in the event
that such Third Party Suit involves potentially criminal or fraudulent activity
of an Indemnifying Party, the Indemnified Party shall have the right, at its
sole option, to defend such Third Party Suit at the expense of the Indemnifying
Party.

     (d) If the Indemnifying Party shall fail to elect to defend against such
Third Party Suit, then the amount of any such Third Party Suit, including all
losses, judgments, expenses and costs incurred by the Indemnified Party in
connection with any defense thereof shall be deemed to be a liability of the
Indemnifying Party hereunder.

     (e) After notice from the Indemnifying Party to such Indemnified Party of
its election to assume the defense thereof, the Indemnifying Party shall not be
liable to the Indemnified Party pursuant to the provisions of Sections 9.1 for
any legal or other expense subsequently incurred by such Indemnified Party in
connection with the defense thereof other than reasonable costs of
investigation, unless (i) the Indemnified Party shall have employed counsel in
accordance with Subsection (c) above, (ii) the Indemnifying Party shall not have
employed counsel reasonably satisfactory to the Indemnified Party to represent
the Indemnified Party within a reasonable time after the notice of the
commencement of the action, or (iii) the Indemnifying Party has authorized the
employment of counsel for the Indemnified Party at the expense of the
Indemnifying Party.

     (f) In the event the Indemnified Party shall have any claim against the
Indemnifying Party hereunder which does not involve a claim or demand by or
against a third party, the Indemnified Party shall promptly notify the
Indemnifying Party of such

                                      B-58
<PAGE>   497

claim, providing reasonable details of the facts giving rise to the claim and a
statement of the Indemnified Party's Loss in connection with the claim, to the
extent such Loss is then known to the Indemnified Party and, otherwise, an
estimate of the amount of the Loss that it reasonably anticipates that it will
incur or suffer; however, failure by the Indemnifying Party to give notice shall
not prejudice any rights contained herein.

     9.3 Cooperation in Defense.   In case of any claim, arbitration or legal
proceeding, the defense of which is assumed by an Indemnifying Party in
accordance with this Article 9, the Indemnified Party, upon request of the
Indemnifying Party, shall provide reasonable cooperation (at the expense of the
Indemnifying Party in accordance with this Article 9) in the defense thereof.

     9.4 Limitations on Indemnification by ATX Stockholders.   Notwithstanding
Section 9.1 or any other provision of this Agreement or applicable law, the ATX
Stockholders' aggregate liability for ATX Losses indemnified pursuant to Section
9.1 is subject to the following limitations:

         (a) The ATX Stockholders shall have no liability for any ATX Loss
     unless notice of a claim for such ATX Loss, specifying in reasonable detail
     the basis for such claim, is made upon ATX Stockholders prior to the
     expiration of the survival periods set forth in Section 10.1. The ATX
     Stockholders' maximum aggregate liability for ATX Losses shall be
     $250,000,000; plus the aggregate amount of any costs, charges and expenses
     (including without limitation legal expenses) incurred by ATX and CoreComm
     in bringing or enforcing any claims against the ATX Stockholders under this
     Agreement.

         (b) The ATX Stockholders shall be liable for ATX Losses (other than ATX
     Losses due to or arising out of any inaccuracy in or any breach of a
     representation, warranty, covenant or agreement of ATX, ATX Merger Sub or
     the ATX Stockholders contained in Sections 3.1, 3.2, 3.3 and 3.20) (the
     "Basket Exclusions"), only if and to the extent that the aggregate ATX
     Losses exceed $10,000,000; provided, however, that the ATX Stockholders
     shall be liable only for amounts in excess of $5,000,000 (including the
     Basket Exclusions); provided further that the ATX Stockholders shall be
     liable for all ATX Losses related to the Basket Exclusions.

     9.5 Mitigation of Losses.

     (a) ATX Losses shall be subject to appropriate mitigation for (i) any
actual recovery from third parties (less attorneys' fees, expenses and other
costs of recovery), (ii) the actual collection of insurance proceeds (less
attorneys' fees, expenses and other costs of recovery, net of any adjustments to
the corresponding insurance premiums).

     (b) Where an Indemnified Party is entitled (whether by right of indemnity,
reimbursement or any other means) to recover from any Person (not being any
employee or officer of an Indemnified Party, but including its or their
insurers) any sum with respect to any matter giving rise to a claim, then
(subject first to being indemnified and secured to the reasonable satisfaction
of an Indemnified Party against all costs, expenses, tax or other liabilities
which may be thereby incurred) the Indemnified Party

                                      B-59
<PAGE>   498

shall take all reasonable steps to enforce such recovery (keeping the
Indemnifying Party fully informed of the progress of any action taken) and
account to the Indemnifying Party for any net amounts that are recovered (not
exceeding the amount previously paid by the Indemnifying Party and after first
taking account of any liability or loss of the Indemnified Party with respect to
which the Indemnifying Party is not liable).

     9.6 Exclusivity.   Following the Closing, the remedies (subject to the
limitations) set forth in this Article 9 shall be the sole remedy for claims for
liability for ATX Losses arising under this Agreement.

     9.7 Indemnification Escrow.   Upon the Recapitalization, 27% of the shares
of ATX Common Stock comprising the Exchange Consideration shall be deposited in
escrow (the "Indemnification Escrow") pursuant to an escrow agreement among ATX,
each ATX Stockholder and an escrow agent selected by such parties with the
consent of CoreComm (the "Indemnification Escrow Agreement"). Such shares
(together with any distributions thereon or the proceeds from the sales thereof)
shall be held in the Indemnification Escrow subject to the terms of the
Indemnification Escrow Agreement to secure the indemnification obligations of
the ATX Stockholders under Section 9.1 hereof, and such assets shall be held and
disbursed in accordance with the terms of the Indemnification Escrow Agreement.
In the event of any claim by ATX against such assets, the shares of ATX Common
Stock shall be valued at the closing price on the business day immediately
preceding the date on which such shares are to be disbursed to an Indemnified
Party in accordance with the terms of the Indemnification Escrow Agreement.

                 X. SURVIVAL OF REPRESENTATIONS AND WARRANTIES

     10.1 ATX, ATX Merger Sub and ATX Stockholders.   Notwithstanding the right
of CoreComm to investigate fully the affairs of ATX, ATX Merger Sub and the ATX
Stockholders and notwithstanding any knowledge of facts determined or
determinable by CoreComm pursuant to such investigation or right of
investigation, CoreComm shall have the right to rely fully upon the
representations, warranties, covenants and agreements of ATX, ATX Merger Sub and
the ATX Stockholders contained in this Agreement or in any document or
certificate delivered pursuant to this Agreement. All such representations,
warranties, covenants and agreements shall survive the execution and delivery of
this Agreement and the Closing hereunder. Except for those representations and
warranties set forth in Section 3.3 hereof (all of which representations and
warranties shall survive without limitation as to time), all representations and
warranties of ATX and ATX Merger Sub contained in this Agreement shall expire
(i) April 30, 2001, and (ii) with respect to any claim related to taxes or
environmental representations and warranties, on the date upon which the
liability to which any such claim may relate is barred by all applicable statues
of limitations.

     10.2 CoreComm.   None of the representations, warranties, covenants and
agreements of CoreComm contained in this Agreement or in any document or
certificate delivered pursuant to this Agreement shall survive the Closing
hereunder other than those covenants that by their terms are to be performed
after the Closing.

or by reason of this Agreement.

     11.10 Severability.   If it is determined that any term or provision of
this Agreement is invalid, illegal or incapable of being enforced by any law or
public policy, all other terms and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transaction contemplated hereby is not affected in any manner
materially adverse to any party. To such end, the provisions of this Agreement
are agreed to be severable. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transaction contemplated hereby is consummated as originally
contemplated to the greatest extent possible.

     11.11 Counterparts.   This Agreement may be executed in one or more
counterparts, all of which shall be deemed to be an original and considered one
and the same agreement and shall become effective when one or more counterparts
have been signed by each of the parties and delivered (including by facsimile
transmission) to the other parties hereto, it being understood that all parties
need not sign the same counterpart.

<PAGE>   510

     During the term of this Agreement and subject to all of the provisions

accordance with clause (i) of Section 1.6 hereof; (iv) pursuant to a bequest or
similar gift or transfer from a Person who is not a Stockholder, including,
without limitation, through the creation of a trust for the benefit of a
Stockholder; (v) pursuant to a will or the laws of descent and distribution from
a Person who is not a Stockholder; or (vi) pursuant to the grant or exercise of
stock options or the receipt of other compensation or benefits involving Voting
Securities granted to a Stockholder in such Stockholder's capacity (if
applicable) as an employee or consultant of the Company or any subsidiary of the
Company; provided, however, that if, in connection with the transfer of Voting
Securities to a Stockholder pursuant to clauses (iv) and (v) of this Section
1.1, a trust, corporation or other entity is formed for the purpose of holding
Voting Securities for the benefit of a Stockholder (other than solely as an
income beneficiary of a trust), then, as a condition precedent to the receipt by
such Stockholder of any direct or indirect beneficial interest in such Voting

requests such Stockholder to do so, only in accordance with the provisions of
Section 1.6 (ii) or (iv), the Voting Securities acquired in violation of this
Section 1.1, provided that any sale may be delayed by the Stockholders to avoid
a violation of Section 16(b) of the Exchange Act or any other provisions of the
Exchange Act or Securities Act, including, without limitation, any applicable
volume limits under Rule 144 of the Securities Act, or any successor rules or
regulations permitting sales of unregistered or otherwise restricted securities.
Each Stockholder hereby acknowledges that any acquisition of Voting Securities
in contravention of this Agreement shall constitute a breach of this Agreement
and that the Company's right to purchase or require the disposition of Voting
Securities pursuant to this Section 1.1 shall not be exclusive and shall be in
addition to any other rights and remedies the Company may have in connection
with a breach of this Agreement.

to such matter, or, (y) in the event of a proposed change of control transaction
for the Company, in the manner recommended to the stockholders by the Board of
Directors of the Company provided that the Board of Directors, prior to such
recommendation, shall have received an opinion from a nationally recognized
investment banking firm to the effect that the transaction or the consideration
to be received by the unaffiliated holders of the Common Stock is fair from a
financial point of view to such stockholders; provided, further, that in the
absence of such opinion such Voting Securities shall be voted as provided in
clause (x) of this Section 1.2.

     Each Stockholder shall take such action as may be required so that all
Voting Securities with respect to which such Stockholder has the legal capacity
to vote or to direct the vote of such Voting Securities as provided for herein
shall be present in person or by proxy at all duly noticed and convened meetings
of holders of Voting Securities for the purpose of determining the presence of a
quorum at such meetings.

deposit any Voting Securities in a voting trust or in any other manner, except
pursuant to this Agreement, subject any Voting Securities to any arrangement or
agreement with respect to the voting thereof.

election of directors of the Company (as such terms are defined in Regulation
14A under the Exchange Act) or initiate, propose or otherwise solicit
stockholders of the Company for the approval of one or more stockholder
proposals at any time, or induce or attempt to induce any other person to
initiate any stockholder proposal; provided, however, that each Stockholder
shall vote any Voting Securities directly or indirectly beneficially owned by
such Stockholder in any "election contest" in accordance with the provisions of
the first paragraph of Section 1.2 hereof.

<PAGE>   512

or encourage the formation of a partnership, limited partnership, syndicate or

control of the Company or acquiring, holding, disposing of or Voting Securities.

     1.6 Disposition of Voting Securities.

     (a) Prior to                   ,(1) no Stockholder shall directly or
indirectly, offer, sell, assign, pledge, encumber or otherwise dispose of or
transfer in any manner any shares of Common Stock held by such Stockholder (the
shares of Common Stock which may not be offered, sold, assigned, pledged,
encumbered or otherwise disposed of during such period being the "Restricted
Shares"), except that the Restricted Shares may be pledged in respect of a
margin loan or to a bona fide third party lending institution provided that the
pledgee shall be bound by the restrictions contained in this sentence; provided
however, that if less than 50% of the Senior Notes (as defined in the Merger
Agreement) issued to the Stockholders pursuant to the Merger Agreement have been
repaid within six (6) months of the Closing (as defined in the Merger
Agreement), the restrictions set forth in this Section 1.6(a), with respect to
25% of the Restricted Shares held by such Stockholder shall terminate on the six
month anniversary of the Closing; provided, however, that disposition of any
such shares that are released from such restrictions shall be subject to the
volume limitations set forth in Rule 144(e) under the Securities Act.

     (b) In addition, except as set forth above no Stockholder shall, directly
or indirectly, offer, sell, assign, pledge, encumber or otherwise dispose of or
transfer in any manner any Voting Securities (or enter into agreements or
understandings with respect to the foregoing), if after such disposition, the
Person holding such Voting Securities would own 5% or more of the Total Voting
Power (or Voting Securities which are convertible into or exercisable for shares

proposed public offering, each Stockholder selling pursuant to such offering
(the "Selling Stockholder") will use his/her/its best efforts (and will instruct
the managing underwriter of any such public offering or broker-dealer to or
through which such public offering is being made to use its best efforts) to
achieve a sufficiently broad public distribution of the securities being offered
(in light of the number of securities being offered), with the intention that no
person or related group of persons should purchase in such public offering
Voting Securities representing 5% or more of the Total Voting Power; (ii)
pursuant to an unsolicited open market sale

Securities representing not more than 1% of the Total Voting Power, as defined
in Section 5.4, (in accordance with the requirements as to the manner of sale
set forth in Rule 144(f) and (g) of the Securities Act or any successor rules or
regulations permitting sales of unregistered or otherwise restricted securities,
if such sale is subject to Rule 144 or such successor rules or regulations) on
any national securities exchange on which the Voting Securities are listed;
(iii) pursuant to a tender offer made by the Company or any subsidiary of the
Company or made by a third person to the stockholders of the Company as to which
the Company's Board of Directors has recommended to the stockholders of the
Company; (iv) pursuant to a privately-negotiated transaction with a Person who
is not a Stockholder; provided, that in no case shall any such sale, transfer or
other disposition under this clause (iv) be made to such Person if, immediately
after such transaction, such Person (based upon the written representation of
such Person, which as a condition precedent to such sale, transfer or other
disposition shall be delivered to such Stockholder and to the Company prior to
the consummation of such transaction), together with its affiliates and
associates would be the direct or indirect beneficial or record owner of Voting
Securities (when added to the Voting Securities (if any) already beneficially
owned by such Person and its affiliates and associates) representing in excess
of 5% of the Total Voting Power; (v) pursuant to a will or the laws of descent
and distribution; provided, that the estate of a Stockholder shall be bound by
the terms and conditions of this Agreement and if, immediately after any
distribution out of such estate, any distributee, together with such
distributee's affiliates and associates would (other than solely as an income
beneficiary of a trust) be the direct or indirect beneficial or record owner of,
or have the right to acquire, Voting Securities (when added to the Voting
Securities (if any) already owned by such distributee and his/her affiliates and
associates representing in excess of 5% of the Total Voting Power, then such
distributee shall, as a condition precedent to receiving such shares of Voting
Securities, agree to be bound by the terms and conditions of a stockholder
agreement having the same terms and conditions as this Agreement; (vi) pursuant
to a bequest or similar gift or transfer to any Person who is not a Stockholder
or; provided that if, immediately after delivery of a bequest or similar gift or
transfer, including, but not limited to, through the creation of a trust, the
recipient, together with such recipient's affiliates and associates (including,
as the case may be, the Stockholder making such transfer), would (other than
solely as an income beneficiary of a trust) be the direct or indirect beneficial
or record owner of, or have the right to acquire, Voting Securities (when added
to the Voting Securities (if any) already owned by such recipient and its
affiliates and associates (including, as the case may be, the Stockholder making
such transfer)) representing in excess of 5% of the Total Voting Power, then
such recipient shall, as a condition precedent to receiving such shares of
Voting Securities, agree to be bound by the terms and conditions of a
stockholder agreement having the same terms and conditions as this Agreement; or
(vii) as a result of any pledge or hypothecation to a bona fide financial
institution to secure a bona fide loan, guaranty or other financial
accommodation or as a result of any foreclosure with respect thereto; provided,
however, that in connection with any transfer by a Stockholder of Voting
Securities pursuant to clauses (v) or (vi) of this Section 1.6 to a trust,

<PAGE>   514

Stockholder retains the authority, as trustee or otherwise, to vote, acquire or
dispose of, or to direct the voting, acquisition or disposition of, Voting
Securities to be held by such trust or other entity, then as a condition
precedent to the transfer of such shares of Voting Securities to such trust or
other entity, such Stockholder shall cause such trust or other entity to be
bound by the terms and conditions of a stockholder agreement having the same or
substantially the same terms and conditions as this Agreement.

     Notwithstanding anything to the contrary contained herein, a Stockholder

the provisions of Section 5 of the Securities Act.

combination or similar transaction with, or a change of control of, the Company
or make or solicit or encourage any Person to make a tender offer for Voting
Securities.

     1.8 Legend on Voting Securities.   Each Stockholder agrees that each
certificate representing its Voting Securities shall bear the following legend,

     provisions of a Stockholder Agreement dated as of             , 2000, among

and the registrar (or registrars) of the Voting Securities against the transfer
of legended Voting Securities held by a Stockholder except in compliance with
the requirements of this Agreement. The Company agrees to remove promptly any
stop transfer order with respect to, and issue promptly either legended (if the
Voting Securities remain subject to the restrictions of this Agreement) or
unlegended certificates in substitution for, certificates for any such Voting
Securities that are no longer subject to or are to be transferred in compliance
with the restrictions contained in this Agreement. Without limiting the
generality of the foregoing, the Company shall promptly remove any stop transfer
order in effect with respect to such certificates, upon the delivery to the
Company of an opinion of counsel to a Stockholder, in form and substance
reasonably satisfactory to the Company, that legended certificates representing
Voting Securities are no longer subject to this Agreement or that such Voting
Securities are being transferred in compliance with the provisions of Sections
1.6, and shall promptly issue unlegended certificates in substitution for such
legended certificates, except if such legended certificates are being
transferred pursuant to Section 1.6 to a transferee who shall be bound by the
terms and conditions of a Stockholder Agreement, in which event the Company may
issue legended certificates.

agrees to provide registration rights to each Stockholder on the terms and
subject to the provisions set forth in Registration Rights Agreement attached as

     3.2 Access to Management.   The Company agrees that so long as a
Stockholder continues to hold 5% or more (or in the case of Debra Buruchian and
Thomas Gravina, 2% or more) of any class of Voting Securities, the Company shall
provide such Stockholder with an opportunity on a regularly scheduled basis to
review with senior management of the Company, significant issues facing the
Company; provided, however, that such Stockholder shall agree (i) to maintain
the confidentiality of any non-public information disclosed to such Stockholder
in any such session, and (ii) if necessary, refrain from engaging in any
transaction involving (x) the Company's securities while in possession of any

public information relates.

     Section 4. Term of Agreement.

     The term of this Agreement shall commence at the Effective Time and shall
terminate with respect to any given Stockholder (but only such Stockholder) (x)
in the case of Michael Karp and The Florence Karp Trust, when such Stockholders
(together with any transferees who are members of such Stockholder's immediate
family or entities described in clause (v) of Section 1.6 hereof) ceased to own
Voting Securities having, in the aggregate, 5% or more of the Total Voting
Power, and (y) in the case of each of Debra Buruchian and Thomas Gravina, when
such Stockholder (together with any transferees who are members of such
Stockholder's immediate family or entities described in clause (v) of Section
1.6 hereof) ceases to own less than 50% of the Voting Securities issued to such
party pursuant to the Recapitalization (after giving effect to any stock splits
or stock dividends), unless the transaction or transactions which resulted in
such Stockholder ceasing to hold such threshold number or percentage of Voting
Securities shall have violated the terms of this Agreement. For purposes hereof,
ownership of Voting Securities shall include record ownership of such securities
as well as beneficial ownership thereof within the meaning of Rule 13d-3 under
the Securities Exchange Act of 1934, as amended.

     Section 5. Miscellaneous.

and agree that irreparable damage would occur in the event any of the provisions
of this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the Company or a
Stockholder, as the case may

                                      B-78
<PAGE>   517

be, shall be entitled to an injunction or injunctions to prevent breaches of the
provisions of this Agreement and to enforce specifically, the terms and
provisions hereof in any court of the United States or any state thereof having
jurisdiction, in addition to any other remedy to which it may be entitled at law
or equity.

     5.2 The Term "Company."   The term "Company" shall be deemed to include any
successor to the Company by way of merger, consolidation, sale of assets or
otherwise, except as the context otherwise requires, it being the intention
hereof that this Agreement shall continue to be binding on each Stockholder
notwithstanding such merger, consolidation, sale of assets or other succession,
unless the provisions of Section 4.2 of this Agreement shall otherwise provide.

     5.3 The Terms "Affiliate," Associate," "Beneficial Owner" "Entity," and
"Person." As used herein, the term "affiliate" shall have the meaning set forth
in Rule 12b-2 under the Exchange Act; the term "beneficial owner" (which shall
include "beneficially owned" or other similar phrasing as used herein) shall
have the meaning set forth in Section 13(d)(3) of the Securities Act; the term
"associate" shall mean (1) a corporation or organization (other than the Company
or a subsidiary of the Company) of which such Person (as defined herein) is an
officer or partner or is, directly or indirectly, the beneficial owner of 10
percent or more of any class of equity securities, (2) any trust or other estate
in which such Person has a substantial beneficial interest or as to which such
Person serves as trustee or in a similar capacity, and (3) any relative or

corporation, joint venture, association, unincorporated organization, trust,

     5.4 The Term "Total Voting Power."   The term "Total Voting Power," as used
in this Agreement, shall mean the aggregate voting power of all Voting
Securities outstanding at the time of any determination which at such time have
ordinary voting power to vote in the election of directors of the Company. In
determining Total Voting Power for purposes of this Agreement, the Stockholder
may conclusively rely on the most recent reports filed by the Company with the
SEC in which the number of Voting Securities outstanding is set forth or from
which Total Voting Power can reasonably be derived, it being understood that
each Stockholder shall not be considered to be in breach of this Agreement if
he/she has acted in good faith on the basis of a determination of Total Voting
Power as contemplated herein.

named hereunder shall be in writing (including wire, telex or similar writing)

                     FORM OF REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT, dated as of                , 2000 (the
"Agreement"), by and between ATX Telecommunications Services, Inc. , a Delaware
corporation (the "Company"), and each of Michael Karp ("Karp"), Debra Buruchian
("Buruchian"), Thomas Gravina ("Gravina") and The Florence Karp Trust (the
"Trust"). Each of Karp, Buruchian, Gravina and the Trust is referred to as a
"Stockholder").

     WHEREAS, pursuant to a Recapitalization Agreement and Plan of Merger, dated
as of March 9, 2000, as amended (the "Recapitalization and Merger Agreement"),
by and among the Company, CoreComm Limited ("CoreComm"), and, with respect to
certain provisions thereof, the Stockholders, ATX Merger Sub, Inc. ("ATX Merger
Sub") and CoreComm Merger Sub, Inc. ("CoreComm Merger Sub") (i) CoreComm has
been merged with and into CoreComm Merger Sub (with each issued and outstanding
share of CoreComm's common stock converted into a share of common stock of
CoreComm Merger Sub) (the "Domestication Merger"); (ii) CoreComm Merger Sub is
being merged with and into the Company (the "Merger"); and (iii) the Company is
being recapitalized by exchanging each pre-recapitalization share of the
Company's common stock for                   shares of the Company's
post-recapitalization common stock, par value $.01 per share (the "Common
Stock"),                   shares of the Company Convertible Preferred Stock,
par value $.01 per share (the "Preferred Stock"), and $150 million in cash and
Senior Notes (as defined in the Recapitalization and Merger Agreement) with a
possible issuance of up to $110 million in notes (the "Recapitalization").

     WHEREAS, the Stockholders are the holders of all of the outstanding pre-
recapitalization shares of the Company's common stock and it is a condition to
the consummation of the recapitalization and the other transactions contemplated
by the Recapitalization and Merger Agreement that the Company grant to the
Stockholders the registration rights and other rights set forth herein; and

     In consideration of the mutual covenants and agreements set forth herein
and for good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto agree as follows:

     1. General; Securities Subject to this Agreement.

     1.1 Grant of Rights.   The Company hereby grants registration rights to the
Stockholders upon the terms and subject to the conditions set forth in this
Agreement. Capitalized terms used herein and not defined shall have the meanings
assigned to such terms in the Recapitalization and Merger Agreement.

     1.2 Registrable Securities.   For the purposes of this Agreement,
"Registrable Securities" means, each of the following: (a) any shares of Common
Stock issued to the Stockholders pursuant to the Recapitalization and Merger
Agreement, (b) any shares of Preferred Stock issued to the Stockholders pursuant
to the Recapitalization and Merger

                                      B-83
<PAGE>   522

Agreement, (c) any shares of Common Stock issued upon conversion of, or as
payment of dividends on, or in exchange for shares of the Preferred Stock issued
pursuant to the Recapitalization and Merger Agreement, and (d) any shares of
Common Stock issued in payment of a dividend on the Senior Notes (as defined in
the Recapitalization and Merger Agreement); provided, however, that shares shall
cease to be Registrable Securities for purposes of this Agreement when a
registration statement covering such Registrable Securities has been declared
effective under the Securities Act by the SEC and all such Registrable
Securities have been disposed of pursuant to such effective registration
statement.

     1.3 Stockholders of Registrable Securities.   A Person is deemed to be a
holder of Registrable Securities whenever such Person (i) is a party to this
Agreement (or a permitted transferee thereof) and (ii) owns of record
Registrable Securities. If the Company receives conflicting instructions,
notices or elections from two or more Persons with respect to the same
Registrable Securities, the Company may act upon the basis of the instructions,
notice or election received from the registered owner of such Registrable
Securities.

     2. Demand Registration Rights.

         2.1 Shelf and Demand Registration.

         (a) Within 15 days following the Closing (as defined in the Merger
     Agreement), the Company shall cause to be filed with the Securities and
     Exchange Commission a Registration Statement registering under Rule 415
     under the Securities Act all Registrable Securities (the "Shelf
     Registration"). The Company shall use its reasonable best efforts to cause
     such Shelf Registration to be declared effective under the Securities Act
     as soon as practicable following the filing thereof, and shall use its
     reasonable best efforts to cause such Shelf Registration to remain
     continuously effective under the Securities Act until such time as the
     securities which have been issued to the Stockholders at the Closing (as
     defined in the Recapitalization and Merger Agreement) may be freely sold
     without regard to the volume limitations under Rule 144 of the Securities
     Act by a Stockholder who is not otherwise an Affiliate of the Company
     within the meaning of Rule 144 (or such shorter period that will terminate
     when all Registrable Securities covered by the Shelf Registration have been
     sold). Subject to the provisions of Section 2.1(d), the Company agrees, if
     necessary, to supplement or make amendments to the Shelf Registration, if
     required by the registration form used by the Company for the Shelf
     Registration or by the instructions applicable to such registration form or
     by the Securities Act or the rules or regulations thereunder.

         (b) At any time on or after the Closing, the Stockholders may make a
     written request (specifying the intended method of disposition) (such
     Stockholders, the "Initiating Common Stockholders") for one additional
     registration under the Securities Act (a "Demand Common Registration") of
     all or part of the shares of Common Stock which constitute such Initiating
     Stockholders' Registrable Securities; provided, however, that, (i) the
     number of shares of Common Stock proposed to be registered by the
     Initiating Common Stockholders in any Demand Common
                                      B-84
<PAGE>   523

     Registration shall not be less than 1,500,000 shares (subject to
     appropriate adjustments to reflect stock splits, stock dividends, corporate
     recapitalizations or similar transactions) as of the date of the request,
     and (ii) the Initiating Common Stockholders shall be the holders as of the
     date of the request of at least 25% of the then outstanding shares of
     Common Stock that constitute Registrable Securities hereunder; provided,
     however, that such Demand Common Registration may be requested by
     Initiating Common Stockholders owning less than 25% of the then outstanding
     shares of Common Stock that constitute Registrable Securities hereunder so
     long as such Initiating Common Stockholders are the holders as of the date
     of the request of at least 10% of the then outstanding shares of Common
     Stock that constitute Registrable Securities hereunder.

         (c) At any time on or after the Closing, the Stockholders may make a
     written request (specifying the intended method of disposition) (such
     Stockholders, the "Initiating Preferred Stockholders") for one additional
     registration under the Securities Act (a "Demand Preferred Registration")
     of all or part of the shares of Preferred Stock which constitute such
     Initiating Stockholders' Registrable Securities; provided, however, that,
     (i) the face value of the shares of Preferred Stock proposed to be
     registered by the Initiating Stockholders shall not be less than
     $80,000,000 as of the date of the request, and (iv) the Initiating
     Preferred Stockholders shall be the holders as of the date of the request
     of at least 25% of the then outstanding shares of Preferred Stock that
     constitute Registrable Securities hereunder.

         (d) If, so long as the Shelf Registration is in effect or at the time a
     demand for a Demand Registration (as defined below) is received by the
     Company, the Company is engaged in, or within 90 days plans to engage in a
     registered public offering for its own account or any other activity which,
     in the good faith determination of the Board of Directors of the Company,
     would (i) be required to be disclosed in a Demand Registration or which,
     under applicable law would require an amendment of or supplement to the
     Shelf Registration, and (ii) be materially and adversely affected by the
     proceeding with any such Demand Registration or amending or supplementing
     the Shelf Registration (each, a "Company Event"), then the Company may at
     its option direct that sales under the Shelf Registration be suspended, and
     requests for a Demand Registration be delayed for a reasonable period of
     time not in excess of three (3) months from the effective date of such
     offering or the date of completion of such other activity, as the case may
     be, such right to delay a Demand Registration or to suspend sales under the
     Shelf Registration to be exercised by the Company not more than once in any
     365-day period; provided, however, that if the Company receives a written
     request from Initiating Common Stockholders or the Initiating Preferred
     Stockholders (the "Initiating Stockholders") to register the Registrable
     Securities of such Stockholders prior to the occurrence of a Company Event,
     then such registration shall not be delayed by any registration statement
     thereafter effected by the Company. In addition, the Company shall not be
     required to effect any Demand Registration within three (3) months after
     the effective date of any other registration statement

                                      B-85
<PAGE>   524

     of the Company (other than the Shelf Registration). Within ten days after
     receipt of a request for a Demand Common Registration or a Demand Preferred
     Registration (each, a "Demand Registration"), the Company shall give
     written notice (the "Notice") of such request to all other Stockholders
     holding the class of stock to which such Demand Registration relates and
     shall include in such registration all Registrable Securities of that class
     that the Company has received written requests for inclusion therein within
     15 days after the Notice is given. Thereafter, in the case of Demand Common
     Registration, the Company may elect to include in such registration
     additional shares of Common Stock issued by the Company. All requests made
     pursuant to this Section 2.1 (other than the Shelf Registration), shall
     specify the class and aggregate number of Registrable Securities to be
     registered.

         2.2 Effective Demand Registration.   The Company shall use reasonable
     commercial efforts to cause any Demand Registration to become effective not
     later than ninety (90) days after it receives a request under Section 2.1
     of this Agreement and to remain effective for the lesser of (i) the period
     during which all Registrable Securities registered in the Demand
     Registration are sold and (ii) one hundred and twenty (120) days; provided,
     however, that if the Initiating Stockholders request the Company to
     withdraw such registration, other than as the result of a breach by the
     Company, it shall constitute a Demand Registration unless the Initiating
     Stockholders promptly pay all of the costs and expenses incurred by the
     Company in connection with such registration.

     2.3 Underwriting Procedures.

         (a) The offering of Registrable Securities pursuant to a Demand
     Registration shall be in the form of a firm commitment underwritten
     offering and the managing underwriter and other underwriters selected for
     such offering shall be selected by the Initiating Stockholders, provided
     that the managing underwriter and other underwriters are reasonably
     acceptable to the Company (having due regard to the experience and
     relationship with the Company of the managing underwriter and the other
     underwriters) (the "Approved Demand Underwriter"). In such event, if the
     Approved Demand Underwriter advises the Company in writing that in its
     opinion the aggregate amount of such Registrable Securities requested to be
     included in such offering is sufficiently large to have a material adverse
     effect on the success of such offering, the Company shall include in such
     registration only the aggregate amount of Registrable Securities that in
     the opinion of the Approved Demand Underwriter may be sold without any such
     material adverse effect and shall reduce pro rata based on the number of
     Registrable Securities included in the request for Demand Registration, the
     amount of Registrable Securities to be included by each Stockholder in such
     registration.

         (b) An offering of Registrable Securities under the Shelf Registration
     may, but need not be, pursuant to an underwritten offering. However, if any
     such offering is to be pursuant to an underwritten offering, the
     Stockholder or Stockholders intending to sell Registrable Securities in
     such underwritten offering shall give the

                                      B-86
<PAGE>   525

     Company written notice of their desire to proceed with an underwritten
     offering under the Shelf Registration. Only one underwritten offering under
     the Shelf Registration shall be permitted, and any such offering must be
     for at least 1,500,000 shares of Common Stock (subject to appropriate
     adjustments to reflect stock splits, stock dividends, corporate
     recapitalizations or similar transactions) or at least $80,000,000 face
     amount of Preferred Stock. The managing underwriter and other underwriters
     selected for such offering shall be selected by the Stockholders seeking to
     sell such shares through such underwriter, provided that the managing
     underwriter and other underwriters are reasonably acceptable to the Company
     (having due regard to the experience and relationship with the Company of
     the managing underwriter and the other underwriters) (the "Approved Shelf
     Underwriter" and together with an Approved Demand Underwriter, an "Approved
     Underwriter").

         (c) Distribution by Underwriters.   The managing underwriter or
     underwriters selected for any offering shall enter into an agreement with
     the Company and the Stockholders whereby the underwriters shall be
     prohibited from (i) distributing 5% or greater of the Registrable
     Securities to any Person in connection with the initial placement of the
     Registrable Securities for the offering and from (ii) distributing 5% or
     greater of the Registrable Securities to any Person for 90 days after such
     initial placement.

     3. Incidental or "Piggy-Back" Registration Rights.

         3.1 Notice of Registration.   If, at any time or from time to time
     prior to the fourth anniversary of the date hereof, the Company shall
     determine to register any of its Common Stock for sale in an Underwritten
     Offering for its own account (other than a registration relating to (i) a
     registration of an employee compensation plan or arrangement adopted in the
     ordinary course of business on Form S-8 (or any successor form) or any
     dividend reinvestment plan or (ii) a registration of securities on Form S-4
     (or any successor form) including, without limitation, in connection with a
     proposed issuance in exchange for securities or assets of, or in connection
     with a merger or consolidation with another corporation) (a "Company
     Registration"), or shall register any of its Common Stock pursuant to a
     demand request for registration by any holder of the Company's Common Stock
     other than the Stockholders (a "Third Party Demand Registration"), the
     Company will promptly give to the Stockholders written notice thereof, and
     include in such registration (subject to Section 3.2) all the Common Stock
     Registrable Securities specified in a written request made by any one or
     more of the Stockholders within ten days after such Stockholder's receipt
     of such written notice from the Company ("Incidental Registration"). The
     right of the Stockholder to have Common Stock Registrable Securities
     included in a registration pursuant to this Section 3.1 shall be
     conditioned upon such Stockholder entering into (together with the Company
     and/or the other holders, if any, distributing their securities through
     such underwriting) an underwriting agreement in customary form with the
     managing underwriter or underwriters selected for such underwriting by the
     Company or by

                                      B-87
<PAGE>   526

     the stockholders who have demanded such registration (the "Company
     Underwriter").

         3.2 Cutback.   If the lead managing underwriter of an offering covered
     by Section 3.1 shall advise the Company in writing on or before the date
     five days prior to the date then scheduled for such offering that, in its
     opinion, the amount of Common Stock (including Common Stock Registrable
     Securities) requested to be included in such registration exceeds the
     amount which can be sold in such offering without adversely affecting the
     distribution of the Common Stock being offered, then the Company will
     include in such registration:

               (i) in the case of a Company Registration, first, any shares
         proposed to be offered by the Company; second, Registrable Securities
         requested to be registered by the Stockholders and any other shares
         requested by other stockholders of the Company, including the
         Stockholders, to be included in such registration, allocated, if
         necessary, pro rata among the Stockholders and such other holders
         requesting such registration on the basis of the number of the shares
         Beneficially Owned at the time; and

               (ii) in the case of a Third Party Demand Registration, first, any
         shares proposed to be offered by the stockholder or stockholders
         exercising their right to cause the Company to proceed with such Third
         Party Demand Registration (the "Initiating Third Party Holders"),
         second, any shares proposed to be offered by the Company, and third,
         Registrable Securities requested to be registered by the Stockholders
         and any other shares requested by other stockholders of the Company,
         including the Stockholders but excluding the Initiating Third Party
         Holders, to be included in such registration, allocated, if necessary,
         pro rata among the Stockholders and such other holders requesting such
         registration on the basis of the number of the shares Beneficially
         Owned at the time;

     provided, however, that in the event the Company will not, by virtue of the
     foregoing cut-back mechanism, include in any such registration all of the
     Common Stock Registrable Securities requested to be included in such
     registration, the Stockholders may, upon written notice to the Company
     given within three days of the time the Stockholders first are notified of
     such matter, reduce the amount of Registrable Securities they desire to
     have included in such registration, whereupon only the Registrable
     Securities, if any, they desire to have included will be considered for
     such inclusion.

         3.3 Right of Termination.   The Company shall have the right to
     terminate or withdraw any registration initiated by it under Section 3.2
     prior to the effectiveness of such registration whether or not the
     Stockholders have elected to include Registrable Securities in such
     registration.

     4. Provisions Applicable to Demand and Piggy-Back Registrations.

         4.1 Expenses.   The Company shall pay all Registration Expenses (as
     defined in Section 6 hereof) incurred in connection with any registration
     pursuant to

                                      B-88
<PAGE>   527

     Section 2 or 3 hereto, unless registration fails to become effective as a
     result of the fault of one or more Stockholders, in which case the Company
     will not be required to pay the Registration Expenses incurred with respect
     to the offering of such Stockholder's or Stockholders' Registrable
     Securities. The Registration Expenses incurred with respect to the offering
     of such Stockholder's or Stockholders' Registrable Securities shall be the
     product of (a) the aggregate amount of all Registration Expenses incurred
     in connection with such registration and (b) the ratio that the number of
     such Registrable Securities bears to the total number of Registrable
     Securities included in the registration.

         4.2 Holdback Agreements.   Each Stockholder agrees not to effect any
     public sale or distribution of any Registrable Securities being registered
     or of any securities convertible into or exchangeable or exercisable for
     such Registrable Securities, including a sale pursuant to Rule 144 under
     the Act, during the ninety (90) day period beginning on the effective date
     of any Demand Registration or Incidental Registration or other underwritten
     offering in which such Stockholder is participating (except as part of such
     registration), if and to the extent requested by any other Stockholders, in
     the case of a non-underwritten public offering, or if and to the extent
     requested by the Company Underwriter, in the case of an under-written
     public offering.

     5. Registration Procedures.

     In connection with any registration statement filed pursuant to this
Agreement, the Company will, as expeditiously as possible:

         (a) in connection with a request pursuant to this Agreement, prepare
     and file with the Commission, after receipt of a request to file a
     registration statement with respect to Registrable Securities, a
     registration statement on any form for which the Company then qualifies or
     which counsel for the Company shall deem appropriate and which form shall
     be available for the sale of such Registrable Securities in accordance with
     the intended method of distribution thereof and, if the offering is an
     underwritten offering, shall be reasonably satisfactory to the Approved
     Underwriters, and use its best efforts to cause such registration statement
     to become effective; provided, however, that before filing a registration
     statement or prospectus or any amendments or supplements thereto, the
     Company shall (i) furnish to the counsel selected by the Stockholder or
     Stockholders making the demand, if any, copies of all such documents
     proposed to be filed, and (ii) notify such counsel and each seller or
     prospective seller of Registrable Securities of any stop order issued or
     threatened by the Commission and take all reasonable actions required to
     prevent the entry of such stop order or to remove it if entered;

         (b) in connection with a registration pursuant to this Agreement (other
     than a Shelf Registration), prepare and file with the Commission such
     amendments and supplements to such registration statement and the
     prospectus used in connection therewith as may be necessary to keep such
     registration statement effective for a period of not more than one hundred
     and twenty (120) days (or such shorter period

                                      B-89
<PAGE>   528

     that will terminate when all Registrable Securities covered by such
     registration statement have been disposed of);

         (c) furnish to each seller of Registrable Securities such number of
     copies of the registration statement, each amendment and supplement thereto
     (in each case including all exhibits thereto), the prospectus included in
     such registration statement (including each preliminary prospectus) and
     such other documents as each seller may reasonably request in order to
     facilitate the disposition of the Registrable Securities owned by such
     seller;

         (d) use reasonable efforts to register or qualify such Registrable
     Securities under such other securities or "blue sky" laws of such
     jurisdictions as any seller or underwriter reasonably requests in writing
     and to do any and all other acts and things that may be reasonably
     necessary or advisable to register or qualify for sale in such
     jurisdictions the Registrable Securities owned by such seller; provided,
     however, that the Company shall not be required to (i) qualify generally to
     do business in any jurisdiction where it is not then so qualified, (ii)
     subject itself to taxation in any such jurisdiction, (iii) consent to
     general service of process in any such jurisdiction or (iv) provide any
     undertaking required by such other securities or "blue sky" laws or make
     any change in its charter or by-laws that the Board of Directors of the
     Company determines in good faith to be contrary to the best interest of the
     Company and its Stockholders;

         (e) use reasonable efforts to cause the Registrable Securities covered
     by such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary by virtue of
     the business and operations of the Company to enable the seller or sellers
     thereof or the Approved Underwriters, if any, to consummate the disposition
     of such Registrable Securities;

         (f) notify each seller of such Registrable Securities at any time when
     a prospectus relating thereto is required to be delivered under the
     Securities Act of the happening of any event as a result of which the
     prospectus included in such registration statement contains an untrue
     statement of a material fact or omits to state any material fact required
     to be stated therein or necessary to make the statements therein, in light
     of the circumstances under which they were made, not misleading, and
     prepare and file with the Commission as soon thereafter as practicable,
     after consultation with the Initiating Stockholders and subject to the
     provisions of Section 2.1(d), a supplement or amendment to such prospectus
     so that, as thereafter delivered to the purchasers of such Registrable
     Securities, such prospectus will not contain an untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading;

         (g) enter into customary agreements (including, in the case of a Demand
     Registration or a single underwritten offering under the Shelf Registration
     by Approved Shelf Underwriters an underwriting agreement in customary form)
     and take such other actions as are reasonably required in order to expedite
     or facilitate the disposition of such Registrable Securities in the manner
     permitted hereby;
                                      B-90
<PAGE>   529

         (h) in the case of either a Demand Registration or a single
     underwritten offering under the Shelf Registration by Approved Shelf
     Underwriter, causing its officers to be available at reasonable times to
     participate in "road shows" and other information meetings organized by the
     managing Approved Demand Underwriter;

         (i) otherwise use reasonable efforts to comply with all applicable
     rules and regulations of the Commission; and

         (j) use reasonable efforts to cause all Registrable Securities covered
     by the registration statement to be listed on each securities exchange or
     market, if any, on which similar securities issued by the Company are then
     listed, provided that the applicable listing requirements are satisfied.

     The Company may require each seller or prospective seller of Registrable
Securities as to which any registration is being effected to furnish to the
Company such information regarding the distribution of such securities and other
matters as may be required to be included in the registration statement.

     Each holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
paragraph (f) of this Section 5, such holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such holder's receipt of the copies
of the supplemented or amended prospectus contemplated by paragraph (f) of this
Section 5 and, if so directed by the Company, such holder shall deliver to the
Company all copies, other than permanent file copies then in such holder's
possession or copies delivered to prospective purchasers, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice. If the Company shall give any such notice, the Company shall extend the
period during which such registration statement shall be maintained effective
pursuant to this Agreement (including the period referred to in paragraph (b) of
this Section 5) by the number of days during the period from and including the
date of the giving of such notice pursuant to paragraph (f) of this Section 5 to
and including the date when each seller of Registrable Securities covered by
such registration statement shall have received the copies of the supplemented
or amended prospectus contemplated by paragraph (f) of this Section 5.

     6. Registration Expenses.   The Company shall pay all expenses incident to
its performance of or compliance with this Agreement; provided, however, that
the Company shall not pay the costs and expenses of any Stockholder relating to
underwriters' commissions and discounts relating to Registrable Securities to be
sold by such Stockholder, brokerage fees, transfer taxes or the fees or expenses
of any counsel, accountants or other representatives retained by the
Stockholders, individually or in the aggregate. All of the expenses described in
this Section 6 that are to be paid by the Company are herein called the
"Registration Expenses."

     7. Indemnification; Contribution.

         7.1 Indemnification by the Company.   The Company agrees to indemnify,
     in the case of any registration statement filed pursuant to this Agreement,
     each seller

                                      B-91
<PAGE>   530

     of any Registrable Securities covered by such registration statement, each
     other person who participates as an underwriter in the offering or sale of
     such securities, and each person, if any, who controls such seller or any
     such underwriter within the meaning of the Securities Act (collectively,
     the "Indemnified Parties") against any losses, claims, damages or
     liabilities to which such Indemnified Party may become subject under the
     Securities Act or otherwise, insofar as such losses, claims, damages or
     liabilities arise out of or are based upon any untrue statement or alleged
     untrue statement of any material fact contained in any registration
     statement under which such securities were registered under the Securities
     Act, any preliminary prospectus, final prospectus or summary prospectus
     contained therein, or any amendment or supplement thereto, or any omission
     or alleged omission to state a material fact required to be stated therein
     or necessary to make the statements therein in light of the circumstances
     in which they were made not misleading, or any violation by the Company of
     the Securities Act or any rule or regulation thereunder applicable to the
     Company; provided, however, that the Company shall not be liable to the
     extent that any loss, claim, or liability arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in such registration statement, any such preliminary
     prospectus, final prospectus, summary prospectus, amendment or supplement
     in reliance upon and in conformity with written information furnished to
     the Company by or on behalf of such Indemnified Party expressly for use in
     the Registration Statement; provided, further, that the Company shall not
     be liable to any seller of Registrable Securities (or to any person who
     acts as an underwriter in such sale or who controls such seller) to the
     extent that any loss, claim, or liability arises out of an untrue
     statement, alleged untrue statement, omission, or alleged omission made in
     any preliminary prospectus if either (a)(i) such seller failed to send or
     deliver a copy of the prospectus with or prior to written confirmation of
     the sale by such seller to the person asserting the claim and (ii) the
     prospectus would have corrected such untrue statement, alleged untrue
     statement, omission or alleged omission; or (b)(x) such untrue statement,
     alleged untrue statement, omission or alleged omission is corrected in an
     amendment or supplement to the prospectus and (y) having been furnished by
     or on behalf of the Company with copies of the prospectus as so amended or
     supplemented, such seller fails to deliver such prospectus as so amended or
     supplemented, with or prior to the written confirmation of the sale by such
     seller to the person asserting the claim.

         7.2 Indemnification by Stockholders.   In connection with any
     registration statement in which a Stockholder is participating, each such
     Stockholder shall furnish to the Company in writing such information and
     affidavits with respect to such Stockholder as the Company reasonably
     requests for use in connection with any such registration statement or
     prospectus and agrees to indemnify, to the fullest extent permitted by law,
     the Company, its officers, directors and agents and each person, if any,
     who controls the Company (within the meaning of the Securities Act) against
     any and all losses, claims, damages, and liabilities resulting from any
     untrue or alleged untrue statement of a material fact or any omission or
     alleged

                                      B-92
<PAGE>   531

     omission of a material fact required to be stated in any registration
     statement, prospectus or preliminary prospectus or any amendment thereof or
     supplement thereto or necessary to make the statements therein (in the case
     of a prospectus, in light of the circumstances under which they were made)
     not misleading, to the extent that such untrue or alleged untrue statement
     or omission is contained in or omitted from, as the case may be, any
     information or affidavit with respect to such Stockholder so furnished in
     writing by such Stockholder expressly for use in any such prospectus or
     preliminary prospectus; provided, however, that the liability of such
     Stockholder shall not exceed the net proceeds received by such Stockholder
     from the sale of its Registrable Securities. Each Stockholder also shall
     indemnify any underwriters of the Registrable Securities, their officers
     and directors and each person who controls such underwriters (within the
     meaning of the Securities Act) to the same extent as provided above with
     respect to the indemnification of the Company; provided, however, that the
     indemnification of such Stockholder shall be limited to the net proceeds
     received by such Stockholder from the sale of its Registrable Securities.

         7.3 Contribution.   If the indemnification provided for in this Section
     7 is unavailable to any indemnified party hereunder in respect of any
     losses, claims, damages, liabilities or expenses referred to herein, then
     the indemnifying party, to the extent such indemnification is unavailable,
     in lieu of indemnifying such indemnified party, shall contribute to the
     amount paid or payable by such indemnified party as a result of such
     losses, claims, damages, liabilities or expenses in such proportion as is
     appropriate to reflect the relative fault of the indemnifying party and
     indemnified parties in connection with the actions that resulted in such
     losses, claims, damages, liabilities or expenses. The relative fault of
     such indemnifying party and indemnified parties shall be determined by
     reference to, among other things, whether any action in question, including
     any untrue or alleged untrue statement of a material fact or omission or
     alleged omission to state a material fact, has been made by, or relates to
     information supplied by, such indemnifying party or indemnified parties,
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such action.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7.3 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person.

     consent of the holders of a majority of the Registrable Securities then
     outstanding, enter into any agreement with any holder or prospective holder
     of any securities of the Company which would allow such holder or
     prospective holder (a) to include such securities in any registration filed
     under Section 2.1(a) hereof, unless under the terms of such agreement, such
     holder or prospective holder may include such securities in any such
     registration only to the extent that the inclusion of such securities will

     the effective date of any registration effected pursuant to Section 2.1.

     register Registrable Securities pursuant to this Agreement shall be
     automatically assignable by each Stockholder to any transferee (other than
     the transferee of such shares in a registered transaction) of all or any
     portion of the Registrable Securities if: (i) the Stockholder agrees in
     writing with the transferee or assignee to assign such rights, and a copy

                 RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

     This Amendment No. 1 to the Recapitalization Agreement and Plan of Merger
(this "Amendment") is made and entered into as of April 10, 2000, by and between
ATX Telecommunications Services, Inc., Thomas Gravina, Debra Buruchian, Michael
Karp, The Florence Karp Trust, CoreComm Limited, ATX Merger Sub, Inc., a
Delaware corporation ("ATX Merger Sub") and CoreComm Merger Sub, Inc., a
Delaware corporation ("CoreComm Merger Sub"). All capitalized terms which are
used but not otherwise defined herein shall have meanings specified in the
Agreement (as defined below).

     WHEREAS, CoreComm, ATX and the ATX Stockholders are parties to that certain
Recapitalization Agreement and Plan of Merger, dated March 9, 2000 (the
"Agreement"), pursuant to which ATX and CoreComm have agreed to combine in order
to advance the long-term business interests of ATX and CoreComm;

     WHEREAS, CoreComm, ATX and the ATX Stockholders desire for ATX Merger Sub
and CoreComm Merger Sub to become parties to the Agreement as contemplated by
Sections 1.1(b) and (c) of the Agreement;

     WHEREAS, the parties hereto desire to clarify the conversion of shares of
CoreComm Common Stock in the Merger; and

     WHEREAS, the parties hereto desire to revise Section 6.18 of the Agreement
as set forth below;

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and for other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

         1.   Amendment to Article III. ATX Merger Sub hereby represents and
     warrants to CoreComm that each of the representations and warranties
     contained in Sections 3.1(b), 3.2(b) and 3.3(c-d) of the Agreement is true
     and correct.

         2.   General Amendment. Effective hereby, each of CoreComm Merger Sub
     and ATX Merger Sub shall become parties to the Agreement and hereby agree
     to comply with all covenants and obligations otherwise provided therein
     which were contemplated to be performed by each of them, respectively, and
     otherwise be subject to the terms and provisions of the Agreement as is
     contemplated therein and herein.

         3.   Clarification of Conversion of CoreComm Common Stock. The parties
     to this Agreement hereby agree that, in the event that the transaction
     identified by CoreComm to ATX on March 6, 2000, as contemplated in Section
     5.18(ii), (the "Voyager Transaction") is consummated prior to the Closing
     of the Merger, then references in Section 1.3 and 1.4 to shares of CoreComm
     Common Stock shall be deemed automatically to include shares of CoreComm
     Common Stock issuable in

                                      B-99
<PAGE>   538

     the Voyager Transaction upon surrender of certificates for Voyager.net,
     Inc. common stock which by the Effective Time have not been surrendered for
     shares of CoreComm Common Stock in accordance with the terms and provisions
     of the definitive documentation for the Voyager Transaction, and the
     references in Section 1.3 and 1.4 to a certificate or certificates for
     shares for CoreComm Common Stock shall be deemed automatically to include
     such certificate or certificates for Voyager.net, Inc. common stock not yet
     surrendered; provided, that the foregoing shall not apply with respect to
     shares of Voyager.net, Inc. common stock and certificates therefore if the
     holder of such Voyager.net, Inc. common stock has demanded appraisal rights
     with respect to such shares in accordance with the DGCL in connection with
     the Voyager Transaction unless and until such Voyager.net, Inc. stockholder
     withdraws such claim or fails to perfect, effectively withdraws or
     otherwise loses any right to appraisal and payment under the DGCL.

         4.   Amendment to Section 6.18. Effective hereby, the following
     paragraph shall be substituted in its entirety for Section 6.18 of the
     Agreement:

     "6.18. Escrow Agreements. ATX, the ATX Stockholders and the Escrow Agent
shall have executed and delivered the Escrow Agreement and the Indemnification
Escrow Agreement, both of which shall remain in full force and effect."

         5.   Other Provisions Unchanged. Except as specifically amended hereby,
     all other terms and conditions of the Agreement shall remain in full force
     and effect. To the extent that the Agreement includes such terms as
     "herein," "hereto," "in this Agreement" and the like, such terms shall be
     interpreted to refer to the Agreement, as modified by this Amendment.

         6.   Counterparts. This Amendment may be executed in separate
     counterparts, each of which shall be an original and all of which taken
     together shall constitute one and the same instrument.

     IN WITNESS WHEREOF, the parties have executed this Agreement on the date
first above written.

                 RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

     This Amendment No. 2 to the Recapitalization Agreement and Plan of Merger
(this "Amendment") is made and entered into as of July 10, 2000, by and between
ATX Telecommunications Services, Inc., Thomas Gravina, Debra Buruchian, Michael
Karp, The Florence Karp Trust, CoreComm Limited, ATX Merger Sub, Inc. and
CoreComm Merger Sub, Inc. All capitalized terms which are used but not otherwise
defined herein shall have meanings specified in the Agreement (as defined
below).

     WHEREAS, CoreComm, CoreComm Merger Sub, ATX, ATX Merger Sub and the ATX
Stockholders are parties to that certain Recapitalization Agreement and Plan of
Merger, dated March 9, 2000, as amended by Amendment No. 1 to the
Recapitalization Agreement and Plan of Merger, dated April 10, 2000 (the
"Agreement"), pursuant to which ATX and CoreComm have agreed to combine in order
to advance the long-term business interests of ATX and CoreComm; and

     WHEREAS, the parties hereto desire to revise the Agreement to reflect that
CoreComm will be merging directly into ATX as opposed to ATX Merger Sub merging
into CoreComm;

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and for other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

     Amendment to Section 1.1(f).   Section 1.1(f) shall be deleted and replaced
in its entirety with the following:

         "At the Effective Time, the separate existence of CoreComm Merger Sub
     shall cease and CoreComm Merger Sub shall be merged (the "Merger") with and
     into ATX (ATX and CoreComm Merger Sub are sometimes referred to herein as
     the "Constituent Corporations" and ATX is sometimes referred to herein as
     the "Surviving Corporation"). The Certificate of Incorporation of ATX as in
     effect immediately prior to the Effective Time (as theretofore amended in
     accordance with Section 5.28 below) shall be the Certificate of
     Incorporation of the Surviving Corporation until thereafter amended as
     provided by the DGCL, and the Bylaws of ATX as in effect immediately prior
     to the Effective Time (as theretofore amended in accordance with Section
     5.28 below) shall be the Bylaws of the Surviving Corporation until
     thereafter amended as provided by the DGCL, the Certificate of
     Incorporation and such Bylaws."

     1.   Amendment to Section 1.3.   Section 1.3 shall be deleted and replaced
in its entirety with the following:

         "1.3   Conversion of CoreComm Common Stock.   As of the Effective Time,
     by virtue of the Merger and without any action on the part of the holder of
     any

                                      B-103
<PAGE>   542

     shares of ATX Common Stock or CoreComm's common stock, par value $.01 per
     share ("CoreComm Common Stock"):

               (a) INTENTIONALLY OMITTED.

               (b) All shares of CoreComm Common Stock that are owned by
         CoreComm as treasury stock or by any Subsidiary of CoreComm shall be
         canceled and retired and shall cease to exist and no consideration
         shall be delivered in exchange therefor. As used in this Agreement, the
         word "Subsidiary" means, with respect to any party, any corporation or
         other organization, whether incorporated or unincorporated, of which
         (i) such party or any other Subsidiary of such party is a general
         partner (excluding partnerships, the general partnership interests of
         which held by such party or any Subsidiary of such party do not have a
         majority of the voting interest in such partnership) or (ii) at least a
         majority of the securities or other interests having by their terms
         ordinary voting power to elect a majority of the Board of Directors or
         others performing similar functions with respect to such corporation or
         other organization is directly or indirectly owned or controlled by
         such party or by any one or more of its Subsidiaries, or by such party
         and one or more of its Subsidiaries.

               (c) Subject to Section 1.4, each issued and outstanding share of
         CoreComm Common Stock (other than shares to be canceled in accordance
         with Section 1.3(b) and shares to be issued under Section 1.3(a)) shall
         be converted into the right to receive one (1) (the "Merger Ratio")
         fully paid and nonassessable shares of ATX Common Stock. All such
         shares of CoreComm Common Stock, when so converted, shall no longer be
         outstanding and shall automatically be canceled and retired and shall
         cease to exist, and each holder of a certificate representing any such
         shares shall cease to have any rights with respect thereto, except the

                                       TO
                 RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

     This Amendment No. 3 to the Recapitalization Agreement and Plan of Merger
(this "Amendment") is made and entered into July 31, 2000, by and between ATX
Telecommunications Services, Inc., Thomas Gravina, Debra Buruchian, Michael
Karp, The Florence Karp Trust, CoreComm Limited, ATX Merger Sub, Inc. and
CoreComm Merger Sub, Inc. All capitalized terms which are used but not otherwise
defined herein shall have meanings specified in the Agreement (as defined
below), and all amendments thereto.

     WHEREAS, CoreComm, CoreComm Merger Sub, ATX, ATX Merger Sub and the ATX
Stockholders are parties to that certain Recapitalization Agreement and Plan of
Merger, dated March 9, 2000, as amended by Amendment No. 1 to the
Recapitalization Agreement and Plan of Merger, dated April 10, 2000, and by
Amendment No. 2 to the Recapitalization Agreement and Plan of Merger, dated July
10, 2000 (the "Agreement"), pursuant to which ATX and CoreComm have agreed to
combine in order to advance the long-term business interests of ATX and
CoreComm; and

     WHEREAS, the parties hereto desire to revise the Agreement to provide for
certain changes to the terms of the Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and for other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

         1. Amendment to Section 1.2(a)(iii).   Section 1.2(a)(iii) of the
     Agreement is hereby amended in its entirety to read as follows:

               (iii) $150 million in cash (subject to certain adjustments set
         forth herein); provided, however, that CoreComm may, at its sole
         discretion, reduce the aggregate amount of cash to be paid by CoreComm
         to the ATX Stockholders to not less than $40 million (subject to
         certain adjustments set forth herein, the "Cash Consideration") and the
         balance of the $150 million payable under this subsection shall be paid
         through the issuance of notes with such terms and conditions as set
         forth in the term sheet attached hereto as Exhibit B (the "Senior
         Notes;" the combination of the Cash Consideration and Senior Notes
         payable hereunder being referred to as the "Notes and Cash
         Consideration;" the Notes and Cash Consideration, together with the ATX
         Common Stock and the ATX Convertible Preferred Stock, are collectively
         referred to as the "Exchange Consideration").(1) The adjustments set
         forth below to the contrary notwithstanding, if the result of the
         adjustments set forth below would be the payment to the ATX
         Stockholders of less than $40 million of the

---------------

1As described in Exhibit B, if Senior Notes are issued the principal amount
thereof shall be increased by up to $9,000,000.
                                      B-109
<PAGE>   548

Notes and Cash Consideration in the form of cash (including adjustments pursuant
to Section 1.2(j)), such adjustments shall, instead of reducing the Cash
Consideration, reduce, on a dollar-for-dollar basis, the principal amount of
Senior Notes to the extent that (but only to the extent that) the ATX
Stockholders would be entitled to an increase in the Notes and Cash
Consideration as a result of the Capital Expenditure Amount as of July 31, 2000
having been greater than $5,877,817. If such adjustment based on the Capital
Expenditure Amount is greater than the reduction in cash, the excess of such
adjustment shall be made by an increase in the principal amount of the Senior
Notes. For avoidance of doubt, the intention of the parties is that any upward
adjustment in the purchase price resulting from capital expenditures shall first
be by way of a setoff against reductions of the cash consideration otherwise due
in accordance with the adjustments below, and any excess over such reduction
shall be by way of an increase in the principal amount of the Senior Notes.

         2. Amendment to Section 1.2(b) through (i).   Sections 1.2(b) through
     (i) of the Agreement are hereby amended in their entirety to read as
     follows:

               (b) ATX shall prepare as of the earlier of (x) the Closing Date
         and (y) August 31, 2000, an unaudited consolidated balance sheet
         (estimated as of the Closing Date or August 31, 2000, as the case may
         be) (the date as of which such balance sheet is dated being the "Target
         Date") and unaudited estimated statements of income and cash flows of
         ATX for the period from the ATX Balance Sheet Date to the Target Date
         (the "Estimated Target Date Financial Statements") from the GAAP
         Audited Financials and the books and records of ATX in accordance with
         GAAP (applied on a consistent basis using the same accounting methods,
         policies, practices, principles and procedures with consistent
         classifications, judgments and estimation methodologies used in
         preparation of the GAAP Audited Financials) and shall set forth the
         Working Capital as of the Target Date ("Estimated Target Date Working
         Capital"), the ATX Debt as of the Target Date (the "Estimated Target
         Date ATX Debt") and the estimated capital expenditures made by ATX and
         the ATX Partnerships during the period from the ATX Balance Sheet Date
         to July 31, 2000 (the "Estimated 7/31 Capital Expenditures Amount").
         ATX shall prepare the Estimated Target Date Financial Statements as
         promptly as practicable, but in no event later than the earlier of (A)
         five (5) business days prior to the scheduled Closing Date, and (B)
         September 15, 2000. ATX shall provide a copy of the Estimated Target
         Date Financial Statements to CoreComm not later than three (3) days
         after its completion, and in any event at least two (2) business days
         prior to the scheduled Closing Date. If the Target Date is the Closing
         Date, ATX shall also deliver to CoreComm, together with the delivery of
         the Estimated Target Date Financial Statements, a detailed schedule of
         the distributions permitted by Section 1.2(j) hereof, if any, that it
         estimates will be made on or prior to the Closing Date (the "Estimated
         Closing Date Distributions"). If the Target Date is August 31, 2000

                                      B-110
<PAGE>   549

         (and August 31, 2000 is not the Closing Date), not later than five (5)
         business days prior to the scheduled Closing Date, ATX shall deliver to
         CoreComm a detailed schedule of the distributions permitted by Section
         1.2(j) which (i) have actually been made subsequent to August 31, 2000
         and prior to (but not including) the date of such schedule (the "Actual
         Distributions"), and (ii) ATX estimates will be made from the date of
         such schedule through the Closing Date (the "Estimated Additional
         Distributions;" the the Actual Distributions together with the
         Estimated Additional Distributions are together referred to as the
         "Estimated Distributions."

               In the event that the Estimated Target Date Financial Statements
         reflect that the Estimated Target Date Working Capital is less than
         zero (such deficiency, the "Estimated Working Capital Shortfall"), then
         the Notes and Cash Consideration shall be reduced (subject to the
         calculation of the final Target Date Financial Statements) by an amount
         equal to the Estimated Working Capital Shortfall. Any such reduction
         shall be made as follows: the aggregate amount of Senior Notes to be
         issued as part of the Notes and Cash Consideration shall be reduced on
         a dollar-for-dollar basis by an amount equal to the lesser of $5
         million and the amount of Estimated Working Capital Shortfall, and, if
         the Estimated Working Capital Shortfall exceeds $5 million, the Cash
         Consideration portion of the Notes and Cash Consideration shall be
         reduced by an amount equal to the amount by which the Estimated Working
         Capital Shortfall exceeds $5 million. If the Estimated Target Date
         Financial Statements reflect that the Estimated Target Date Working
         Capital is greater than zero (such excess, the "Estimated Working
         Capital Excess") then the Notes and Cash Consideration shall be
         increased (subject to the calculation of the final Target Date
         Financial Statements) by increasing the aggregate principal amount of
         Senior Notes to be issued at the Closing by an amount equal to the
         amount of the Estimated Working Capital Excess. The Estimated Working
         Capital Shortfall or Estimated Working Capital Excess, as applicable,
         shall be the "Estimated Target Date Working Capital Adjustment."

               In the event that the Estimated Target Date Financial Statements
         reflect that Estimated Target Date ATX Debt is greater than zero, then
         the Notes and Cash Consideration shall be reduced (subject to the
         calculation of the final Target Financial Statements) by reducing the
         amount of the Cash Consideration portion of the Notes and Cash
         Consideration by an amount equal to the Estimated Target Date ATX Debt.

               In the event that the Estimated Target Date Financial Statements
         reflect that the Estimated 7/31 Capital Expenditure Amount is less than
         $5,877,817 (the "Capital Expenditure Target Amount,") the Notes and
         Cash Consideration shall be reduced (subject to the calculation thereof
         based on the final Target Date Financial Statements) by reducing the
         aggregate principal amount of Senior Notes to be issued at the Closing
         by an amount equal to the difference between the Capital Expenditure
         Target Amount and the 7/31

                                      B-111
<PAGE>   550

         Capital Expenditure Amount. In the event that the Estimated Target Date
         Financial Statements reflect that the 7/31 Capital Expenditure Amount
         is greater than the Capital Expenditure Target Amount, the Notes and
         Cash Consideration shall be increased (subject to the calculation
         thereof based on the final Target Date Financial Statements) by
         increasing the aggregate principal amount of Senior Notes to be issued
         at the Closing by an amount equal to the lesser of (i) $1,500,000, and
         (ii) the difference between the Capital Expenditure Target Amount and
         the 7/31 Capital Expenditure Amount (the adjustments contemplated by
         this paragraph being the "Capital Expenditure Adjustment").

               (c) Within ninety (90) days after the Closing Date (the
         "Financial Statements Delivery Date"), ATX shall cause to be prepared
         and delivered to the Stockholder Representative (as defined below) a
         proposed unaudited balance sheet and proposed unaudited statements of
         income and cash flows (the "Proposed Target Date Financial Statements")
         prepared in accordance with GAAP (applied on a consistent basis using
         the same accounting methods, policies, practices, principles and
         procedures with consistent classifications, judgments and estimation
         methodologies that were used in preparation of the GAAP Audited
         Financials) setting forth the Working Capital of ATX and ATX Debt as of
         the Target Date, and the Capital Expenditures of ATX and the ATX
         Partnerships for the period from (and excluding) the ATX Balance Sheet
         Date through (and including) July 31, 2000. For purposes of this
         Section 1.2, the Stockholder Representative shall mean BDO Seidman,
         LLP. ATX shall also prepare and deliver to the Stockholder
         Representative at the same time as it delivers the Proposed Target Date
         Financial Statements, its calculation of the amount of the
         distributions made pursuant to Section 1.2(j) subsequent to the Target
         Date (the "ATX Distribution Calculation").

               (d) The Stockholder Representative shall have a period of thirty
         (30) days (the "Review Period") from the date on which ATX delivers the
         Proposed Target Date Financial Statements and the ATX Distribution
         Calculation to the Stockholder Representative pursuant to Section
         1.2(c), to review the Proposed Target Date Financial Statements and the
         ATX Distribution Calculation. If, prior to the expiration of the Review
         Period, the Stockholder Representative does not deliver a Dispute
         Notice (as defined below) to ATX, the unaudited balance sheet and
         unaudited statements of income and cash flows included in the Proposed
         Target Date Financial Statements and the ATX Distribution Calculation
         shall be deemed to be final and binding upon ATX and the ATX
         Stockholders for purposes of determining the Working Capital of ATX,
         the ATX Debt as of the Target Date, the Capital Expenditures of ATX for
         the period from the ATX Balance Sheet Date through July 31, 2000 and
         the amount of the distributions made pursuant to Section 1.2(j)
         subsequent to the Target Date (the "Post-Target Date Distributions").
         The unaudited balance sheet and unaudited statements of income and cash
         flows included in the Proposed Target Date Financial

                                      B-112
<PAGE>   551

         Statements shall not become final and binding at the end of the Review
         Period, nor shall the ATX Distribution Calculation become final and
         binding if, prior to the expiration of the Review Period, the
         Stockholder Representative delivers a written notice to ATX (the
         "Dispute Notice") setting forth in reasonable detail the disagreements
         that the Stockholder Representative has with the unaudited balance
         sheet and/or either of the unaudited statements of income and cash
         flows included in the Proposed Target Date Financial Statements and/or
         with the ATX Distribution Calculation and the effect which such
         disagreements would have on the calculation of any of the Working
         Capital of ATX, the ATX Debt as of the Target Date, the Capital
         Expenditures of ATX for the period from the ATX Balance Sheet Date
         through July 31, 2000, the ATX Distribution Calculation or the amount
         (or form) of Notes and Cash Consideration payable to the ATX
         Stockholders. If the Stockholder Representative delivers a Dispute
         Notice prior to the end of the Review Period, the representatives of
         ATX and the Stockholder Representative shall have a ten (10) day period
         (the "Settlement Period") from the date of the delivery of the Dispute
         Notice to attempt to resolve any dispute set forth in the Dispute
         Notice and to agree upon an unaudited balance sheet and unaudited
         statements of income and cash flows and/or upon the amount of the
         Post-Target Date Distributions, which shall be binding on ATX and the
         ATX Stockholders for purposes of this Agreement and to agree upon the
         Working Capital of ATX, the ATX Debt as of the Target Date, the Capital
         Expenditures of ATX for the period from the ATX Balance Sheet Date
         through July 31, 2000 and the Post-Target Date Distributions. If the
         Stockholder Representative and ATX have not arrived at an agreement
         during the Settlement Period, then, at any time following the
         termination of the Settlement Period, either the Stockholder
         Representative or ATX may submit the issue in dispute to the
         Philadelphia, Pennsylvania office of PricewaterhouseCoopers LLP (the
         "Accountant") for resolution in accordance with this Section. In
         resolving any disputed item, the Accountant (i) shall be bound by the
         provisions of this Section 1.2, (ii) may not assign a value to any item
         greater than the greatest value for such item claimed by either party
         or less than the smallest value for such item claimed by either party,
         (iii) shall make its determination based solely on information
         submitted by the parties and not by independent review and (iv) shall
         be instructed to issue a report containing its resolution of the
         disputed issue or issues (the "Accountant's Report") within thirty (30)
         days following submission of the dispute. The Accountant's Report shall
         be delivered by the Accountant to ATX and the Stockholder
         Representative, and shall be final and binding on ATX and the ATX
         Stockholders for purposes of this Agreement. The fees charged by the
         Accountant shall be paid by ATX.

               (e) During the period of any dispute within the contemplation of
         this Section 1.2, the ATX Stockholders, the Stockholder Representative
         and their representatives (including counsel and accountants) shall
         have reasonable access during normal business hours to all books,
         records, employees, offices

         extent required to complete their review of the Target Date Financial
         Statements and their examination of the calculations with respect to
         the ATX Distribution Calculation and shall be permitted to review the
         working papers (subject to the execution of customary waivers, releases
         and indemnifications), if any, of ATX or its auditor relating to the
         Target Date Financial Statements or the ATX Distribution Calculation;
         provided that any such access shall not unreasonably interfere with the
         day-to-day operations of ATX and shall be limited to those items
         related to the assessment of the Target Date Financial Statements or
         the ATX Distribution Calculation, as the case may be, and matters
         related thereto. ATX and CoreComm or their auditors shall cooperate
         with the ATX Stockholders and other representatives of the ATX
         Stockholders in facilitating such review.

               (f) In the event that the final Target Date Financial Statements
         reflect that the Working Capital of ATX as of the Target Date is less
         than zero (such deficiency, the "Final Working Capital Shortfall"),
         then the Notes and Cash Consideration shall be reduced by an amount
         equal to the excess of zero over the Final Working Capital Shortfall
         (the "Final Shortfall"); provided, however, that the Final Shortfall
         shall be adjusted to reflect any adjustments to the Notes and Cash
         Consideration previously made due to an Estimated Target Date Working
         Capital Adjustment. Any such reduction shall be made to by reducing the
         Cash Consideration and/or the Notes to the same extent as they would
         have been reduced had the Final Shortfall been used at the Closing
         rather than the Estimated Working Capital Adjustment. If the Final
         Target Date Balance Sheet reflects that the Working Capital of ATX as
         of the Target Date is greater than zero (a "Final Working Capital
         Excess") then the Notes and Cash Consideration shall be increased by
         issuing additional Senior Notes to the ATX Stockholders in an aggregate
         amount equal to the excess of the Final Working Capital Excess over the
         amount of Working Capital generated subsequent to July 31, 2000;
         provided, however, that the Final Working Capital Excess (and any
         related amounts to be paid) shall be adjusted to reflect any
         adjustments to the Notes and Cash Consideration previously made due to
         an Estimated Target Date Working Capital Adjustment.

               (g) In the event that the final Target Date Financial Statements
         reflect that the ATX Debt is greater than zero (such amount the "Final
         ATX Debt"), then the Notes and Cash Consideration shall be decreased by
         reducing the Cash Consideration portion of the Notes and Cash
         Consideration as provided in Section 1.2(i); provided, however, that
         the Final ATX Debt shall be adjusted to reflect any adjustments to the
         Closing Exchange Consideration previously made due to any Estimated
         Target Date ATX Debt.

               (h) In the event that the final Target Date Financial Statements
         reflect that the capital expenditures made by ATX during the period
         from the ATX Balance Sheet Date to July 31, 2000 (the "7/31 Capital
         Expenditure

                                      B-114
<PAGE>   553

         Amount") is less than the Estimated 7/31 Capital Expenditure Amount,
         then the Notes and Cash Consideration shall be decreased by decreasing
         the aggregate principal amount of Senior Notes by an amount equal to
         the excess of the Estimated 7/31 Capital Expenditure Amount over the
         7/31 Capital Expenditure Amount; provided, however, if the Estimated
         7/31 Capital Expenditure Amount was an amount in excess of $1,500,000
         over the Capital Expenditure Target Amount, then, for purposes of the
         calculation required by this subsection (h), the Estimated 7/31 Capital
         Expenditure Amount shall be deemed to have been an amount equal to
         $1,500,000 over the Capital Expenditure Target Amount. For purposes of
         Section 1.2, the 7/31 Capital Expenditure Amount shall include only
         amounts paid or payable by ATX prior to the Target Date which have been
         purchased and installed by ATX on or prior to July 31, 2000.

               (i) In the event of any reduction to the Notes and Cash
         Consideration occurring after the Closing by operation of Subsections
         (f) through (h) above which involves a reduction in the Cash
         Consideration, the ATX Stockholders shall be jointly and severally
         liable to pay to ATX in cash the amount in question. In the event of
         any reduction of the Notes and Cash Consideration occurring after the
         Closing by operation of Subsections (f) through (h) above which
         involves a reduction in the aggregate principal amount of the Senior
         Notes, ATX shall be entitled to cause each of the Senior Notes to be
         reduced by its pro-rata portion of such amount; provided, however, that
         in lieu of having the principal amount of any Senior Note reduced, the
         ATX Stockholder who originally received the indebtedness evidenced by
         such Senior Note may deliver to ATX a personal note having the same
         interest rate, payment and maturity dates as the Senior Notes in an
         amount equal to the amount which such ATX Stockholder's Senior Note
         would have been reduced; provided further, however, that such personal
         notes may only be delivered in respect of such ATX Stockholder's
         ratable share of $5,000,000. For purposes hereof, an ATX Stockholder's
         ratable share shall mean a fraction, the numerator of which is the
         aggregate principal amount of Senior Notes actually issued to such ATX
         Stockholder at the Closing (without giving effect to any post-Closing
         adjustment thereof pursuant to Sections 1.2(f) through (h) hereof) and
         the denominator of which is the aggregate amount of all Senior Notes
         actually issued to the ATX Stockholders at the Closing (without giving
         effect to any post-Closing adjustment thereof pursuant to Sections
         1.2(f) through (h) hereof).

         3. Amendments to Section 1.2(j). Section 1.2(j) of the Agreement is
     amended as follows:

               (a) The period at the end of clause (ii) of Section 1.2(j) is
         deleted and a semicolon is inserted in lieu thereof followed by the
         word "or."

                                      B-115
<PAGE>   554

               (b) A new clause (iii) is added following clause (ii) and reading
         as follows:

                    (iii) pay fees and expenses of ATX in connection with the
              transactions contemplated by this Agreement (such fees and
              expenses include any and all investment banking, legal, accounting
              and similar fees and expenses payable by ATX in connection with
              the transactions contemplated hereby).

               (c) The following additional language is inserted following (but
         not as part of) clause (iii):

                    The Notes and Cash Consideration shall be reduced by
              reducing the Notes and Cash Consideration by an amount equal to
              any distribution made in accordance with this Section 1.2(j), such
              reductions being made as follows: the amount of Notes and Cash
              Consideration, and the portion thereof constituting the Cash
              Consideration, shall be reduced on a dollar for dollar basis by an
              amount equal to the Estimated Distributions permitted to be made
              pursuant to clauses (i) and (ii) of this Section 1.2(j); and the
              amount of Notes and Cash Consideration, and the portion thereof
              payable in Senior Notes, shall be reduced on a dollar for dollar
              basis by an amount equal to the Estimated Distributions that
              constitute distributions permitted to be made pursuant to clause
              (iii) of this Section 1.2(j). If the distributions permitted to be
              made pursuant to clauses (i) and (ii) of this Section 1.2(j)
              exceeds the amount of the Estimated Distributions in respect
              thereof, ATX shall be entitled to be paid, and the ATX
              Stockholders shall be jointly and severally liable to pay to ATX,
              an amount in cash equal to the amount by which the actual amount
              of the distributions permitted to be made pursuant to such clauses
              (i) and (ii) exceeds the amount of the Estimated Distributions in
              respect thereof. If the distributions permitted to be made
              pursuant to clause (iii) of this Section 1.2(j) exceeds the amount
              of the Estimated Distributions in respect thereof, ATX shall be
              entitled to cause each of the Senior Notes to be reduced by its
              pro-rata portion of the actual amount of the distributions
              permitted to be made pursuant to such clause (iii) to the extent
              that such amount exceeds the amount of the Estimated Distributions
              in respect thereof. The foregoing notwithstanding, any payment
              made subsequent to August 31, 2000 by ATX to any ATX Stockholder
              to the extent that such payment constitutes the repayment of funds
              advanced in cash by such ATX Stockholder to ATX subsequent to
              August 31, 2000 in order to fund ATX's working capital
              requirements for the period following August 31, 2000 through the
              Closing Date shall not be reflected in any purchase price
              adjustment and ATX shall make such reimbursements, if not already
              made, at or prior to the Closing Date. Anything in this Section
              1.2(j) to the contrary notwithstanding, under no circumstances

                                      B-116
<PAGE>   555

              may the aggregate amount of all distributions permitted by this
              Section 1.2(j) exceed $25,000,000.

         4. Amendments to Section 1.2(k).   Section 1.2 (k) of the Agreement is
     amended as follows:

               (a) The definition of the term "ATX Capital Expenditure
         Obligation" is amended to read in its entirety as follows:

              amount and for those categories of items set forth on Section 1.2
              of the ATX Disclosure Schedule.

               (b) The definition of the term "ATX Debt" is amended to read in

              liabilities, as set forth on the Estimated Target Date Financial
              Statements, the Proposed Target Date Financial Statements and the
              final Target Date Financial Statements, as applicable.

               (c) The definition of the term "Capital Expenditure Adjustment"
         is deleted in its entirety.

         amount required to fund capital expenditures scheduled to be made
         subsequent to August 1, 2000 in accordance with the ATX business plan
         heretofore provided by ATX to CoreComm. Any such loan shall be at
         reasonable commercial terms. If this Agreement shall be terminated
         prior to the consummation of the Merger as a result of a breach thereof
         by ATX or an ATX Stockholder or a failure to satisfy any of the
         conditions set forth in Sections 6.1, 6.2, 6.5, 6.13 through 6.15,
         6.19(c), 6.20 and 6.22 of the Agreement, all amounts provided by
         CoreComm to ATX shall be repaid, together with accrued unpaid interest
         to the date of repayment and without set-off, not later than thirty
         days following such termination. If this Agreement is terminated prior
         to the consummation of the Merger for any reason other than as set
         forth in the preceding sentence, no

         repayment or other obligations in respect thereof.

         8. Amendment to Section 6.10.   Section 6.10 of the Agreement is
     amended to read in its entirety as follows:

         restrictions that are likely to have a Material Adverse Effect whether
         imposed by the FCC or any other Governmental Entity.

         13. Amendment to Exhibits.   Exhibits A, B, C and G to the Agreement
     are hereby superseded and replaced in their entirety with Exhibits A, B, C
     and G attached hereto, respectively.

         14. Proxy Statement.   Subject to obtaining the approval thereof of all
     parties in interest, CoreComm shall use its reasonable best efforts to
     cause an amended Schedule 14A relating to the transactions contemplated by
     the Agreement to be filed with the Securities and Exchange Commission
     within three (3) business days following the execution and delivery of this
     Amendment by all parties hereto. As soon as practicable following the
     filing of a definitive proxy statement with the Securities and Exchange
     Commission, having due regard for the rules and policies of the Securities
     and Exchange Commission, CoreComm will mail definitive proxy materials to
     its stockholders and will convene a meeting of its shareholders to consider
     the transactions contemplated by the Agreement not later than 30 days
     following the date of mailing of the definitive proxy materials to the
     CoreComm stockholders.

         15. Conduct in the Ordinary Course.   ATX acknowledges that
     notwithstanding the fact that the working capital adjustment provided for
     in Section 1.2 of the Agreement shall be based on working capital of ATX as
     of August 31, 2000 (if the Closing Date is subsequent to August 31, 2000),
     ATX shall continue to be obligated to conduct its business as required by
     Section 5.3 of the Agreement until the Closing Date; provided, however that
     the ATX Stockholders and their Affiliates may make advances to ATX to fund
     ATX's working capital requirements in the ordinary course consistent with
     past practices, which advances shall not be deemed to constitute a breach
     of Section 5.3 of the Agreement.

         16. Financing Terms.   If CoreComm undertakes its proposed bank and its
     proposed Rule 144a financing prior to Closing, such financing shall be
     completed on terms which are not materially different from, in a manner
     materially adverse to CoreComm, the terms heretofore described to the ATX
     Stockholders. If either such financing is completed on terms materially
     different from those described to the ATX Stockholders, and such
     differences are materially adverse to CoreComm, CoreComm shall immediately
     notify the ATX Stockholders of such event, and absent a waiver by the ATX
     Stockholders of such noncompliance, CoreComm shall not be permitted to
     borrow under the Senior Notes described herein, and the remainder of this
     amendment shall remain in full force and effect. "Materially different"
     shall be considered to be any adverse modification to any term of such
     financings by at least 15% (other than the amount of each type of
     financing), which

                                      B-119
<PAGE>   558

     may not be increased. The foregoing bank financing must be one
     comprehensive financing, including the syndication thereof. The intent is
     that CoreComm will enter the market to obtain one bank financing
     arrangement to be completed at one time in an amount between $100 million
     and $200 million. It is not contemplated that CoreComm will do two or more
     separate bank financings that do not close simultaneously. However, nothing
     herein is intended to limit CoreComm's ability to structure such bank
     financing in a customary manner, including, but not limited to, multiple
     tranches, staggered drawing and other standard provisions. In addition,
     upon delivery to the ATX Stockholders of a term sheet reasonably acceptable
     to the ATX Stockholders, the foregoing provisions (and their counterparts
     in Exhibit B) shall be deemed to apply to a bridge financing in addition to
     the bank and 144a financings. Such bridge financing will be subject to the
     same constraints described herein (and in Exhibit B) that apply to the bank
     and 144a financings.

         17. Stock Option Plan; etc.   Not later than seven (7) business days
     following the date of this Amendment, CoreComm shall deliver to ATX a
     proposal outlining employee stock option arrangements for ATX as well as
     term sheets outlining employment and/or consulting services to be provided
     to CoreComm by Thomas Gravina and Debra Buruchian subsequent to the
     Closing.

         18. Letter of Credit.   CoreComm shall cause to be posted a letter of
     credit, not to exceed $900,000, which shall be absolute and unconditional
     supporting ATX's leasehold obligations in respect of the rental of
     approximately 25,000 square feet of office space located in Bala Cynwyd,
     Pennsylvania. If this Agreement shall be terminated under conditions which
     would result in ATX being obligated to repay any capital expenditure
     advances made by CoreComm pursuant to Section 5.34 of the Agreement,
     without regard to any changes made herein, then ATX shall be obligated to
     take all actions necessary in order to promptly and effectively relieve
     CoreComm of any liability which it may have in respect of such letter of
     credit. In the event that the Agreement is terminated and ATX occupies the
     office space under such lease for at least 30 days following such
     termination, then ATX shall be required to replace CoreComm on the letter
     of credit.

         19. Other Provisions Unchanged.   Except as specifically amended
     hereby, all other terms and conditions of the Agreement shall remain in
     full force and effect. To the extent that the Agreement includes such terms
     as "herein," "hereto," "in this Agreement" and the like, such terms shall
     be interpreted to refer to the Agreement, as modified by this Amendment.

         20. Counterparts.   This Amendment may be executed in separate
     counterparts, each of which shall be an original and all of which taken
     together shall constitute one and the same instrument.

                        DELAWARE GENERAL CORPORATION LAW

SEC.262. APPRAISAL RIGHTS.

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec.228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a corporation and
also a member of record of a nonstock corporation; the words "stock" and "share"
mean and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251 (other than a merger effected pursuant to
sec.251(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or
sec.264 of this title:

         (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec.251 of this title.

         (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec.251, 252, 254, 257, 258, 263 and 264 of this title to accept for

               a. Shares of stock of the corporation surviving or resulting from
         such merger or consolidation, or depository receipts in respect
         thereof;

                                       D-1
<PAGE>   569

               b. Shares of stock of any other corporation, or depository
         receipts in respect thereof, which shares of stock (or depository
         receipts in respect thereof) or depository receipts at the effective
         date of the merger or consolidation will be either listed on a national
         securities exchange or designated as a national market system security
         on an interdealer quotation system by the National Association of
         Securities Dealers, Inc. or held of record by more than 2,000 holders;

               c. Cash in lieu of fractional shares or fractional depository
         receipts described in the foregoing subparagraphs a. and b. of this
         paragraph; or

               d. Any combination of the shares of stock, depository receipts
         and cash in lieu of fractional shares or fractional depository receipts
         described in the foregoing subparagraphs a., b. and c. of this
         paragraph.

         (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

         (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

                                       D-2
<PAGE>   570

         (2) If the merger or consolidation was approved pursuant to sec.228 or
     sec.253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     primafacie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon

                                       D-3
<PAGE>   571

the merger or consolidation. Within 120 days after the effective date of the
merger or consolidation, any stockholder who has complied with the requirements
of subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial

                                       D-4
<PAGE>   572

proceedings and may proceed to trial upon the appraisal prior to the final
determination of the stockholder entitled to an appraisal. Any stockholder whose
name appears on the list filed by the surviving or resulting corporation
pursuant to subsection (f) of this section and who has submitted such
stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

Board of Directors
Voyager.net, Inc.
4660 South Hagadorn Road; Suite 320
Lansing, MI 48823

Members of the Board:

     We understand Voyager.Net, Inc. ("Voyager" or the "Company"), CoreComm
Limited ("CoreComm") and CoreComm Group Sub I, Inc., a wholly owned subsidiary
of CoreComm ("Acquisition Sub") propose to enter into an Agreement and Plan of
Merger, dated March 12, 2000 (the "Merger Agreement"), which provides, among
other things, for the merger (the "Merger") of Acquisition Sub with and into
Voyager. Pursuant to the Merger, Voyager will become a wholly owned subsidiary
of CoreComm and each outstanding share of common stock, par value $0.0001 per
share (the "Voyager Common Stock"), of Voyager other than shares held in
treasury or held by CoreComm or any affiliate of CoreComm or the Company, will
be converted into the right to receive $3.00 a share in cash and a certain
number of shares of common stock, par value $0.01 per share (the "CoreComm
Common Stock"), of CoreComm, determined pursuant to a certain formula set forth
in the Merger Agreement (collectively, the "Consideration"). The terms and
conditions of the Merger are more fully set forth in the Merger Agreement.

     We also understand CoreComm, ATX Telecommunications Services, Inc. ("ATX"),
and the ATX Stockholders have entered into a Recapitalization Agreement and Plan
of Merger dated as of March 9, 2000 (the "ATX Merger Agreement") which provides,
among other things, for the acquisition of ATX through a merger of a redomiciled
CoreComm with and into a wholly-owned subsidiary of ATX (the "ATX Merger"). We
note the consummation of the Merger Agreement is not contingent upon the
consummation of the ATX Merger Agreement. Capitalized terms used but not
otherwise defined herein shall have the respective meanings ascribed thereto in
the Merger Agreement and the ATX Merger Agreement.

     You have asked for our opinion as to whether the Consideration to be
received by the holders of shares of Voyager Common Stock pursuant to the Merger
Agreement is fair from a financial point of view to such holders.

     For purposes of the opinion set forth herein, we have:

         (i) reviewed certain publicly available financial statements and other
     information of the Company and CoreComm;

                                       E-1
<PAGE>   574
                                         [Morgan Stanley Dean Witter Letterhead]

         (ii) reviewed certain internal financial statements and other financial
     and operating data concerning the Company, CoreComm, and ATX prepared by
     the managements of the Company, CoreComm, and ATX, respectively;

         (iii) reviewed certain financial projections prepared by the
     managements of the Company, CoreComm, and ATX, respectively;

         (iv) discussed the past and current operations and financial condition
     and the prospects of the Company, including information relating to certain
     strategic, financial and operational benefits anticipated from the Merger,
     with senior executives of the Company;

         (v) discussed the past and current operations and financial condition
     and the prospects of CoreComm, including information relating to certain
     strategic, financial and operational benefits anticipated from the Merger
     and the ATX Merger, with senior executives of CoreComm;

         (vi) discussed the past and current operations and financial condition
     and the prospects of ATX, including information relating to certain
     strategic, financial and operational benefits anticipated from the ATX
     Merger, with senior executives of ATX and CoreComm;

         (vii) reviewed the pro forma impact of the Merger and the ATX Merger on
     CoreComm's consolidated capitalization and financial ratios;

         (viii) reviewed the reported prices and trading activity for the
     Voyager Common Stock and the CoreComm Common Stock;

         (ix) compared the financial performance of the Company, CoreComm, and
     ATX and the prices and trading activity of the Company Common Stock and the
     CoreComm Common Stock with those of certain other comparable
     publicly-traded companies and their securities;

         (x) participated in discussions and negotiations among representatives
     of the Company, CoreComm and their legal advisors;

         (xi) reviewed the Merger Agreement, the ATX Merger Agreement and
     certain related documents; and

         (xii) performed such other analyses and considered such other factors
     as we have deemed appropriate.

     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. We have relied upon the assessment of the managements of the
Company, CoreComm, and ATX of their ability to retain key employees of their
respective companies. With respect to the financial projections, including
information relating to certain strategic, financial and operational benefits
anticipated from the Merger and the ATX Merger, we have assumed they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the future financial performance of the Company, CoreComm, and
ATX. In addition, we have assumed the Merger will be consummated

                                       E-2
<PAGE>   575
                                         [Morgan Stanley Dean Witter Letterhead]

in accordance with the terms set forth in the Merger Agreement, including that
the Merger will be treated as a tax-free merger and/or exchange pursuant to the
Internal Revenue Code of 1986. We have not made any independent valuation or
appraisal of the assets or liabilities of the Company, CoreComm, or ATX, nor
have we been furnished with any such appraisals. Our opinion is necessarily
based on financial, economic, market and other conditions as in effect on, and
the information made available to us as of, the date hereof.

     We have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will receive a fee for our services.

     It is understood this letter is for the information of the Board of
Directors of the Company, except this opinion may be included in its entirety in
any filing made by the Company in respect of the Merger with the Securities and
Exchange Commission. In addition, this opinion does not in any manner address
the price at which the CoreComm Common Stock will trade following the
announcement or consummation of any of the proposed transactions of CoreComm,
and Morgan Stanley expresses no opinion or recommendation as to how the holders
of the Voyager Common Stock should vote at the shareholders' meeting held in
connection with the Merger.

     Based on the foregoing, we are of the opinion on the date hereof that the
Consideration to be received by the holders of shares of Voyager Common Stock
pursuant to the Merger Agreement is fair from a financial point of view to such
holders.

                                          Very truly yours,

                                          MORGAN STANLEY & CO. INCORPORATED

Board of Directors
CoreComm Limited
110 East 59th Street,
New York, NY 10022

Gentlemen:

     You have requested our opinion as to the fairness from a financial point of
view to CoreComm Limited (the "Company") of the Stock Consideration and the Cash
Consideration (as defined below), in the aggregate, to be exchanged for each
share of common stock, par value $.0001 per share ("Seller Common Stock"), of
Voyager.net, Inc. ("Seller") by the Company pursuant to the Agreement and Plan
of Merger (the "Agreement"), dated as of March 12, 2000, among the Company,
CoreComm Group Sub I, Inc., a wholly owned subsidiary of the Company (the
"MergerCo"), and Seller. Pursuant to the Agreement, MergerCo will be merged with
Voyager.net (the "Merger") and each outstanding share of Seller Common Stock not
owned by the Company, MergerCo or their subsidiaries, will be converted into (i)
that number of shares of common stock, par value $.01 per share, of the Company
(the "Company Common Stock") equal to the ratio derived from dividing $14.00 by
$47.875 (the "Exchange Ratio") subject to cash in lieu of fractional shares of
Company Common Stock and subject to adjustment, as more fully set forth below
(the "Stock Consideration"); and (ii) cash in the amount of $3.00, without any
interest thereon, plus any cash in lieu of fractional shares of Company Common
Stock (the "Cash Consideration"). The Exchange Ratio will be adjusted at the
effective time of the Merger as follows: (i) if the Average Trading Price (as
defined below) of the Company Common Stock is greater than $56.97, then the
Exchange Ratio will be adjusted such that the aggregate value (based on the
Average Trading Price) of the Stock Consideration will be equal to the value the
Stock Consideration would represent if the Average Trading Price were equal to
$56.97 and there were no adjustments to the Exchange Ratio as contemplated by
Section 3.1 of the Agreement; (ii) if the Average Trading Price is equal to or
greater

than $33.03 and is less than $41.17, then the Exchange Ratio will be adjusted
such that the aggregate value (based on the Average Trading Price) of the Stock
Consideration will be equal to the value the Stock Consideration would represent
if the Average Trading Price was equal to $41.17 and there were no adjustments
to the Exchange Ratio as contemplated by Section 3.1 of the Agreement; and (iii)
subject to the provisions of Section 10.1 of the Agreement, if the Average
Trading Price is less than $33.03, then the Exchange Ratio will be equal to the
number that it would be set to in (ii) above if the Average Trading Price was
equal to $33.03. The Average Trading Price is computed as the volume weighted
average trading price of Company Common Stock for 10 randomly selected trading
days out of the 20 consecutive trading days ending on the last day of trading
prior to the closing of the Merger.

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Company having provided investment banking services in
conjunction with the pending acquisition of ATX Telecommunications Inc., and
having been retained to undertake a study to render our opinion in connection
with the transaction contemplated by the Agreement. Goldman, Sachs & Co.
provides a full range of financial advisory and securities services and, in the
course of its normal trading activities, may from time to time effect
transactions and hold securities, including derivative securities, of the
Company or Seller for its own account and for the accounts of customers.

     In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of the
Company for the year ended December 31, 1998; the Registration Statement on Form
S-1 of Seller relating to the initial public offering of Seller, including the
prospectus therein dated July 20, 1999; certain interim reports to stockholders
and Quarterly Reports on Form 10-Q of the Company and Seller; certain other
communications from the Company and Seller to their respective stockholders;
certain internal financial analyses and forecasts for the Company prepared by
the management of the Company; certain internal financial analyses and forecasts
for Seller prepared by the management of Seller and approved for use in
connection with this opinion by the management of the Company (the "Seller
Forecasts"); and certain estimates of operating synergies projected by the
management of the Company to result from the Merger (the "Synergies"). We also
have held discussions with members of the senior management of the Company and
Seller regarding their assessment of the strategic rationale for, and the
potential benefits of, the transaction contemplated by the Agreement and the
past and current business operations, financial condition and future prospects
of their respective companies. In addition, we have compared certain financial

and stock market information of the Company and Seller with similar financial
information and stock market information for certain other companies the
securities of which are publicly traded, reviewed the financial terms of certain
recent business combinations in the Internet service provider industry
specifically and in other industries generally and performed such other studies
and analyses as we considered appropriate.

     We have relied upon the accuracy and completeness of all of the financial
and other information discussed with or reviewed by us and have assumed such
accuracy and completeness for purposes of rendering this opinion. In that
regard, we have assumed with your consent that the Seller Forecasts and
Synergies have been reasonably prepared and reflect the best currently available
estimates and judgments of the Company. In addition, we have not made an
independent evaluation or appraisal of the assets and liabilities of the Company
or Seller or any of their subsidiaries and we have not been furnished with any
such evaluation or appraisal. Our advisory services and the opinion expressed
herein are provided for the information and assistance of the Board of Directors
of the Company in connection with its consideration of the transaction
contemplated by the Agreement and such opinion does not constitute a
recommendation as to how any holder of Company Common Stock should vote with
respect to such transaction.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the Stock
Consideration and the Cash Consideration, in the aggregate, to be exchanged
pursuant to the Agreement is fair from a financial point of view to the Company.

                                          Very truly yours,

New York, NY 10022

Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to CoreComm Limited (the "Company") of the Stock Consideration and the Cash
Consideration (as defined below), in the aggregate, to be paid by the Company
pursuant to the Recapitalization Agreement and Plan of Merger, dated as of March
9, 2000, and as amended on April 10, 2000, July 10, 2000 and July 31, 2000 (the
"Agreement"), among the Company, ATX Telecommunications Services, Inc. (the
"Seller"), CoreComm Merger Sub, Inc. and ATX Merger Sub, Inc. and Thomas
Gravina, Debra Buruchian, Michael Karp and The Florence Karp Trust
(collectively, the "ATX Stockholders") in connection with the acquisition of all
of the equity interests of the ATX Stockholders in the Seller. Pursuant to the
Agreement, the aggregate consideration will be paid to the ATX Stockholders by
way of a recapitalization of the Seller followed by a merger of a subsidiary of
the Company and the Seller pursuant to which each outstanding share of Company
common stock, par value $.01 per share ("Company Common Stock"), will be
converted into one share of ATX common stock, par value $.01 per share ("ATX
Common Stock"). The directors and officers of the Company will become the
directors and officers of the Seller and the name of the Seller shall be changed
to the name of the Company. Pursuant to the Agreement, the ATX Stockholders will
receive (i) the number of shares of ATX Common Stock equal to $500 million
divided by $40.328, subject to adjustment as set forth below (the "Common Stock
Consideration"); (ii) 250,000 shares of Senior Convertible Preferred Stock
convertible into ATX Common Stock, at an initial exercise price of $32.11
(subject to adjustment as set forth in Exhibit A to the Agreement) (the
"Preferred Stock Consideration," and collectively with the Common Stock
Consideration, the "Stock Consideration"); and (iii) $150 million in cash, of
which up to $110 million may

be paid in three year senior notes, at the Company's option, plus up to an
additional $9 million of three year senior notes, subject to the terms of the
Agreement and Exhibit B thereto (the "Cash Consideration"). The Common Stock
Consideration will be adjusted if the volume weighted average trading price of
the Company Common Stock during the ten trading days prior to the closing date
of the transaction is greater than $46.38 (the "Collar Stock Price"). In such a
case, the number of shares of ATX Common Stock to be issued to the ATX
Stockholders will be adjusted such that the aggregate value of the ATX Common
Stock received by the ATX Stockholders, based on the volume weighted average
trading price of the Company Common Stock during the ten trading days prior to
the closing date of the transaction, is increased to equal the original value
($500 million) multiplied by a fraction, the numerator of which is the Collar
Stock Price and the denominator of which is $40.328. The Collar Stock Price is
subject to adjustment as more fully set forth in the Agreement.

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Company having provided certain investment banking services to
the Company, and having acted as its financial advisor in connection with, and
having participated in certain of the negotiations leading to, the Agreement.
Goldman, Sachs & Co. provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold securities, including derivative securities,
of the Company or Seller for its own account and for the accounts of customers.

     In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of the
Company for the year ended December 31, 1999; audited cash basis financial
statements of the Seller for the two years ended December 31, 1997 and draft
GAAP basis financial statements of the Seller for the three years ended December
31, 1999 and six months ended June 30, 2000; certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company; certain other
communications from the Company to its stockholders; certain other information
related to the Seller; certain internal financial analyses and forecasts for the
Company prepared by the management of the Company; and certain internal
financial analyses and forecasts for Seller prepared by the management of Seller
and approved for use in connection with this opinion by the management of the
Company (the "Seller Forecasts"). We also have held discussions with members of
the senior management of the Company and Seller regarding their assessment of
the strategic rationale for, and the potential benefits of, the transaction
contemplated by the Agreement and the past and current business operations,
financial condition and future prospects of their respective companies. In
addition, we have compared certain financial information of the Company and
Seller with similar financial information and stock market information for
certain other companies, the securities of which are publicly traded, reviewed
the financial terms of certain recent business

                                       G-2

combinations in the competitive local exchange carrier and telecommunications
industries and performed such other studies and analyses as we considered
appropriate.

     We have relied upon the accuracy and completeness of all of the financial
and other information discussed with or reviewed by us and have assumed such
accuracy and completeness for purposes of rendering this opinion. In that
regard, we have assumed with your consent that the Seller Forecasts have been
reasonably prepared and reflect the best currently available estimates and
judgments of the Company. In addition, we have not made an independent
evaluation or appraisal of the assets and liabilities of the Company or Seller
or any of their subsidiaries and we have not been furnished with any such
evaluation or appraisal. Our advisory services and the opinion expressed herein
are provided for the information and assistance of the Board of Directors of the
Company in connection with its consideration of the transaction contemplated by
the Agreement and such opinion does not constitute a recommendation as to how
any holder of Company Common Stock should vote with respect to such transaction.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the Stock
Consideration and the Cash Consideration, in the aggregate, to be paid by the
Company pursuant to the Agreement is fair from a financial point of view to the
Company.

                                          Very truly yours,

                                          /s/ GOLDMAN, SACHS & CO.

                                     PART I

ITEM 1.  BUSINESS

INTRODUCTION


    We are a holding company whose main asset is our wholly-owned subsidiary,
CoreComm, Inc. We intend to pursue other opportunities (in addition to those
through CoreComm, Inc.) in the telecommunications industry as they arise.

    We are an innovative communications company that provides integrated
telephone, Internet and data services to business and residential customers in
targeted markets throughout the United States. We are exploiting the convergence
of telecommunications and information services through our "Smart LEC(SM)"
network strategy. Our Smart LEC (Local Exchange Carrier) network strategy
involves the ownership of switches and the leasing of the unbundled local loop
combined with the provisioning of an IP-based, national network. This
configuration of local and national owned and leased facilities allows us to
deliver a wide range of communications services over a network architecture
which we design to be capital efficient and primarily requires success-based
incremental capital. Our goal is to expand our facilities, geography and
services to become a leading switch-based communications provider in selected
major markets across the United States.

    We currently offer local and long distance telephone, Internet access and
high-speed data services to business and residential customers located
principally in the following states: Ohio, Illinois, Michigan, New York and
Massachusetts. As of December 31, 1999, we had more than 100,000 business and
residential local telephony access lines in service and approximately 95,000
Internet customers. We currently operate an asynchronous transport mode (ATM)
network, which connects approximately 90 cities using approximately 50,000 route
miles of leased broadband circuits. This network will allow us to take advantage
of economies of scale in the delivery of voice, video and data. We have been
developing our multi-service offerings since 1996 and have recently expanded our
products to include high speed services utilizing Digital Subscriber Line (DSL)
technology. With DSL, a single copper loop can be used to deliver telephony and
high speed data services simultaneously. We are currently in various stages of
constructing our Smart LEC network in six of the largest markets in the U.S.,
which represent approximately 18 million access lines.

    Management's approach to its network, back office and customer acquisition
will be critical to our success, as well as the following key components of our
strategy:

    o    target large, underserved segments in concentrated metropolitan areas,
         addressing the underlying demand for consumer choice in traditional
         telephony as well as growing demand for high-speed data services;

    o    capture multiple revenue streams through offering customers bundled
         service offerings, differentiated from other providers;

    o    deliver "Internet Centric" product offerings and support to our
         customers;

    o    leverage proven management talent; and

    o    utilize Smart LEC strategy to maximize speed to market, minimize
         investment risk and increase returns on capital.

Business Strategy Overview

    A core part of our business strategy is to offer bundled communications
services, including local and long distance telephony services, Internet access
and high speed data services, all with a single bill. We believe that an
integrated telephony and Internet strategy utilizing DSL technology will be
particularly appealing to our targeted customer base and will significantly
enhance our ability to attract, retain and gain additional revenues from our
subscribers.

    Our service offerings are based on the following customer proposition:
"Customers buy what they need and pay for what they get." We combine and price
our products to give the customer increased flexibility, choice, and "value for
money," while also enhancing convenience and simplicity. With this strategy, we
believe that we can capture a larger share of our customers' communications
expenditures and increase customer retention. In addition, we are currently
investigating ways to add video services, including multichannel television, as
a part of our bundled offerings. Our bundling of services is differentiated from
other incumbent operators because we face fewer regulatory requirements, and can
often be differentiated from other operators because we are not constrained by
the technical limits or cost structure of a less advanced or less capital
efficient network architecture. We believe that our DSL proposition is
especially important as we compete against data service providers utilizing
cable modems, who have difficulty guaranteeing a direct correlation between
price paid and speed of access received.

    The Internet is a key management tool in the marketing, provisioning and
billing of our services, as well as in the ongoing support of our customers. We
also use the Internet as a sales tool by attracting customers through our web
site, www.core.com. We are actively developing and incorporating systems to
deliver "Internet Centric" operational support systems which are planned to add
functionality in the areas of electronic billing, web-based customer care and
e-commerce and e-services. We use the Internet as an efficient means of
communication with our business and residential customers, providing on-line
sign-up and self-provisioning of services. We believe that using the Internet to
communicate with the customer will be not only convenient for the customer, but
will also increase our operating efficiency. We believe that by encouraging the
self-provisioning of communications products, especially in the broader
residential market, we will particularly attract the most data-intensive and
higher margin customers at lower customer acquisition and operating costs.

    We intend to focus on both residential and small to medium-sized business
customers, including the Small Office/Home Office (SOHO) market, located in
major metropolitan areas in the United States. These segments contain many
communications-intensive customers that we believe are often underserved by both
existing incumbent carriers and new entrants. We seek to attract customers in
these segments by offering innovative services, superior customer service and
overall value. By targeting both of these sectors, we expand our potential
revenue base, leverage our marketing costs over a greater number of potential
customers and increase network utilization with more subscribers. We believe
that marketing and provisioning through the Internet will allow us to deploy our
strategy more rapidly than we could with only a direct sales force.

Continuity of Management

    Our management has extensive experience in developing and marketing bundled
communications services, building proprietary back office systems to support
residential and business customers, and designing and constructing large
integrated communications networks. Our management team's accomplishments in the
telecommunications industry span nearly 20 years. There are several members of
this team that have worked together for a decade or more:

    o    Our President and Chief Executive Officer, Barclay Knapp, was a member
         of the original management team at Cellular Communications, Inc. (CCI),
         which was an original applicant for cellular licenses in the United
         States in 1982. Mr. Knapp is also the President and CEO of NTL
         Incorporated.

    o    Our Chairman, George Blumenthal,  was a member of the original
         management team of Cellular Communications,  Inc. Mr.
         Blumenthal also serves as the Chairman of NTL.

    o    Our Chief Operating Officer, Patty Flynt, joined Cellular
         Communications, Inc. in 1989, where she was the director of its
         Management Information Services division. Ms. Flynt also served as the
         MIS director at NTL.

    In the key areas of our operations, our management includes individuals who
have worked with CCI, NTL and their historical affiliates for many years and
have significant telecommunications industry experience. Below is a partial list
of several of those individuals and their area of expertise:

</TABLE>


    The continuity of this team is due to their success in working together
throughout the corporate lineage that began with Cellular Communications, Inc.
in 1981. In addition to these individuals, there are other members of our
management team and staff who were part of CCI, or part of a later joint venture
between CCI and AirTouch Communications, Inc. that was formed in 1991. Several
of our directors have also been involved with each of these companies. CCI was
acquired by AirTouch Communications, Inc. in 1996.

    Out of Cellular Communications, Inc., several publicly traded companies
were spun-off.  Our management team developed these other communications
companies:

    o    NTL Incorporated, a telecommunications, cable television and Internet
         provider which operates principally in the United Kingdom and
         Continental Europe. Giving effect to recently announced acquisition
         agreements, NTL's franchise areas cover approximately 12 million homes,
         representing approximately 50% of the homes and an even larger share of
         the businesses in the United Kingdom. NTL has already achieved an
         industry leading customer penetration rate of 48% in the original areas
         it built-out and marketed.

    o    Cellular Communications of Puerto Rico, Inc. (CCPR), which operated the
         dominant cellular business in Puerto Rico and the U.S. Virgin Islands,
         and from which CoreComm Limited was spun-off in 1998.

    o    Cellular Communications International, Inc. (CCIL), which was a
         co-founder of Ominitel Pronto Italia, S.p.A., which owns the second
         cellular license in Italy.

    The core management team remained intact and guided the above companies to
substantial success, culminating in the acquisitions of each of CCI, CCIL and
CCPR by major telecommunications companies.

Communications Industry

    We are participating in the large and rapidly changing U.S. wireline
telecommunications industry. We believe that the wireline telecommunications
industry benefits from positive price elasticity, as well as growing,
non-cyclical demand for services. According to the U.S. Census Bureau, the total
wireline segment of the U.S. telecommunications market was estimated to be
approximately $208 billion in 1998. Approximately 50% of this revenue is derived
from local service and network access. In addition, demand for access to the
Internet and data services is having a significant effect on the U.S.
communications industry, and is expected to continue its rapid growth. Various
estimates project this segment to grow significantly over the next several
years.

    As demonstrated on the chart below, as a wireline telecommunications
services provider, CoreComm is operating in the largest of the communications
related industries, which represents significant market opportunities for us:

The Smart LEC(SM) Overview

    Our Smart LEC strategy is designed to allow us to enter communications
markets rapidly and to offer a variety of operating benefits, including:
improved operating margins, enhanced control of the customer experience,
success-based capital expenditures, and higher overall returns on capital. In
addition, we believe that the efficiency and broad reach of this network
strategy, in conjunction with our diversified product offering, enable us to
operate under a business plan which requires only a small share of each of our
target markets for a successful return on investment.



                                       4


<PAGE>   589



    The Smart LEC network strategy combines the building and owning of key
network facilities with the leasing of other services from the Incumbent Local
Exchange Carriers (ILECs) and other telecommunications carriers under the
following general principles:

    We build those parts of the network which we believe:

    o    significantly improve operating margins;

    o    are necessary to enhance the services to the customer; and

    o    are not generally available from other providers.

    Conversely, we lease those portions of the network which we believe:

    o    are disproportionately expensive to build;

    o    are readily available to be leased economically from other providers;
         and

    o    do not impact our ability to interact with the customer.

    We have deployed our Smart LEC facilities in Columbus, Ohio, Cleveland, Ohio
and Chicago, Illinois and are currently developing three additional markets:
Detroit, Michigan, New York, New York and Boston, Massachusetts. These six
markets comprise approximately 18 million total access lines. In connection with
these markets, we are in the process of establishing collocation facilities in
approximately 133 ILEC central offices. We have also identified approximately 30
additional markets where we intend to deploy our Smart LEC network in 2000-2002.
We currently deliver our Internet services over our broadband ATM network, which
has approximately 125 points of presence and approximately 50,000 route miles of
leased broadband circuits throughout the United States.

    Based upon our historical experience we are developing sophisticated
proprietary integrated systems and procedures that support all aspects of our
business, including customer provisioning systems, billing systems, and customer
care and collections support systems. Additionally, our systems support
electronic bonding with the ILEC in each of our markets. We believe that an
effective back office is essential to efficiently serving our customers and
achieving successful overall customer satisfaction and retention.

BUSINESS STRATEGY

    Our objective is to become a leading provider of integrated communications
services in our target markets. We believe that we will successfully compete
with the incumbent operators and achieve attractive returns on capital by
pursuing the following key strategies:

    Provide Services to both Business and Residential Customers. We focus on
marketing and packaging our services with product offerings that are tailored to
small-to-medium-sized business customers and communications-intensive
residential markets. Because our networks are capital efficient and because we
lease the "last mile" to the customer, we believe that our business model
uniquely allows us to serve profitably both the business and residential
communities. We believe that each segment offers certain advantages: the
small-to-medium-sized business market offers high volume and revenue per
customer, as well as increased geographical concentration of users; the
residential market offers a large, undeserved, growing market with significantly
less competition from other providers. For example, in Ohio we are one of only a
few competitive providers that market local telecommunications services to the
residential market. In addition, targeting both sectors allows us to leverage
the fixed cost aspects of our network and operations.

    Offer Bundled Services. We provide our customers with "one-stop shopping,"
offering local and long distance telephony, Internet and data services. Our
services are packaged and priced in bundles which give the customer increased
flexibility, choice, and "value for money". We emphasize offerings which are
easy to value by the consumer, and allow them to "buy what they need and pay for
what they get." We typically offer a platform of basic services and then create
ways for customers to add additional services easily and conveniently according
to customer preferences. Our current service offerings include: local dial tone
and local calling; enhanced telephony features, such as call waiting; long
distance calling services; dial-up and dedicated Internet access; and data
services. Our integrated offerings enhance convenience by giving the customer
one point of contact for all of these services, providing the services on a
single bill and simplifying the decision-making process. In addition to
attracting customers, we believe this strategy also improves our profitability
by increasing our average revenue per customer with additional higher margin
services, reducing customer acquisition and other operating costs, and improving
customer retention.


                                       5


<PAGE>   590

    Own and Operate Capital Efficient Networks. Our strategy is to provide our
full range of communications services over our capital efficient, switch-based
network infrastructure which combines the building of key network facilities
with the leasing of other elements from the ILEC or other telecommunications
carriers. We believe that our network strategy offers a variety of benefits
including: attractive operating margins, control of the customer experience,
greater speed to market, broad geographic reach, ability to serve both
businesses and residential customers, success-based capital expenditures, and
higher overall returns on capital.

    "Internet Centric" Strategy. We use the Internet as a key tool of our
business strategy. First, Internet access is one of our core service offerings.
We believe that demand for access to the Internet will continue to grow rapidly
in both the business and residential markets, and that our bundled Internet and
telephony product offerings will be attractive to potential customers. Second,
we currently use our www.core.com web site as a sales tool where customers can
sign up for service, to increase awareness about CoreComm and our products and
services, and to access the large and growing number of users of the World Wide
Web. We also intend to use the Internet to be able to efficiently communicate
with virtually every CoreComm customer. We will provide on-line sign-up, feature
selection, billing, moves/adds/changes, and customer care. We currently offer
customers the ability to sign up online and the option to receive their bills
via e-mail, and are in the process of expanding our systems for these additional
on-line services. We believe that communicating with the customer electronically
will significantly increase our operating efficiency by reducing our sales
costs, customer service costs and billing costs, as well as our bad debt
expense. We also believe that this strategy will provide added convenience for
the customer, which will further differentiate us from our competitors.

    Effective Marketing Over Wide Areas. We develop and utilize effective and
efficient marketing techniques to attract customers. We believe that our network
will allow us to leverage our fixed cost infrastructure to reach wide geographic
areas within our target markets. In addition, the ability to resell ILEC
services expands our overall potential service area even further. Our ability to
offer targeted, customer-convenient services over wide areas enables us to
utilize mass marketing strategies and other efficient methods of communicating
our offerings to our potential customers. We believe that these initiatives will
increase the awareness of the CoreComm brand and attract new customers in our
target markets.

    Distinguish CoreComm From Its Competitors. Our strategies seek to
differentiate us from other communications providers. To satisfy customer needs,
we offer an integrated bundle of services that is not typically offered by a
single provider, and package these services into product offerings that are
unique in their emphasis on simplicity, choice and flexibility. We can
differentiate our service offerings in part because we are less constrained by
regulatory requirements than ILECs, and not as limited by less capital efficient
networks as other operators. In addition, we offer customer service and support
which is superior to what customers have often experienced in the past with
their ILEC or other providers. We have developed our own sophisticated back
office systems to enable us to do so effectively and efficiently. We believe
that our on-line billing and customer service will further differentiate the way
we interact with customers. Through these and other factors, we try to create an
image for CoreComm that emphasizes us as an important member of the community,
offering our services over broad areas, to both business and residential
customers, with superior reliability and service. We believe differentiating
CoreComm in this manner will help us attract and retain our customers.

    Leverage Experience of Proven Management. Our management team has had
significant experience in developing several successful communications companies
in the U.S., the United Kingdom and other countries. We believe that our
management's experience will enhance our ability to execute our business plan,
and will contribute to our overall operational success and results. Our
management has designed attractive, bundled communications services and product
offerings. In addition, our management has previously developed its own internal
systems for billing, MIS and customer care. We believe that a high quality back
office is critical for effectively and efficiently serving the customer. Many
members of our management team have worked together for 10 to 15 years. Our
senior management founded and operates NTL Incorporated, a large
telecommunications, cable television and Internet provider which operates
principally in the United Kingdom and Continental Europe. At NTL, management has
had experience competing against incumbent operators by offering business and
residential customers bundled packages of integrated communications services,
including telephony, cable TV and Internet access. NTL has developed creative
marketing and packaging strategies which have delivered industry leading
customer penetration rates (48% versus the industry average of 32%) and churn
rates which are less than half the industry average. Our senior management has
also been involved with other communications ventures, including Cellular
Communications, Inc., Cellular Communications of Puerto Rico, Inc., and Cellular
Communications International, Inc. which operated cellular businesses in Ohio
and Michigan, Puerto Rico, and Italy, respectively. In these ventures, our
management has typically achieved successful operating results, developed
significant experience competing against incumbent operators, built and
maintained sophisticated communications networks and back office support
systems, and gained recognition in the communications industry and the capital
markets. CoreComm represents an effort to capitalize on this history of
experience and operational success to exploit the significant communications
opportunities in the U.S.


                                       6
<PAGE>   591
    Expand Through Strategic Acquisitions. We have expanded and grown our
operations through strategic acquisitions. We look for acquisitions that enhance
our ability to execute our business strategy, including adding complementary
network and facilities, increasing revenues, and gaining management talent. To
this end, in 1999 we completed the acquisitions of MegsINet Inc. ("MegsINet"), a
Chicago based Internet service provider, and the assets of USN Communications,
Inc. ("USN"), a CLEC in the midwest and northeast providing service to business
customers. In addition, we recently announced that we have entered into
definitive agreements to acquire ATX Telecommunications, Inc. ("ATX"), a "smart
build" CLEC and integrated communications provider serving the mid-Atlantic
states, and Voyager.net, Inc. ("Voyager.net"), the largest independent full
service Internet communications company in the midwest and Great Lakes region.
We intend to continue to pursue acquisition opportunities which would accelerate
the growth and success of our operations.

THE SMART LEC(SM) NETWORK

    The Smart LEC strategy allows us to implement our own switch-based
telecommunications network without the significant additional expense, time
commitment and general financial risk of building our own complete local loops
and transmission facilities. We believe this strategy will improve our overall
return on capital and lower the level of risk associated with the execution of
our business plan, based on the following general advantages:

     o   reduced capital expenditures associated with leasing rather than
         building complete local loop and transport facilities;

     o   greater certainty of return from success-based capital spending;

     o   increased network utilization as a result of the access to multiple
         revenue streams and the ability to increase leased capacity
         incrementally; and

     o   lower overall market penetration requirements as a result of reduced
         network costs.

Advantages of the Smart LEC network

        We believe that this network strategy offers a variety of specific
benefits including:

        Lower Overall Cost -- We believe that the Smart LEC network can be
    deployed at a much lower cost than building conventional networks. The cost
    of conventional networks includes the cost of all of the network facilities
    included in the Smart LEC build, plus the construction of conduit, transport
    capacity and associated infrastructure to connect network access points,
    switch facilities and customers. The deployment of these transmission route
    components involves significant expense, and their elimination under our
    strategy considerably decreases our capital expenditure requirements.
    Whereas the construction of full network facilities has been estimated to
    cost between $1,000 to $3,000 per line, depending on the specifications of
    the network, we estimate that our Smart LEC network will cost less than $500
    per line, while still providing comparable basic telephony services and
    additional advanced services.

        Lower Required Customer Penetration -- Due to the reduced cost of
    building the Smart LEC network, our business model requires a lower level of
    customer penetration to be successful as compared to a full-facilities
    network. Because there is a reduced amount of up-front investment, we
    believe that we can gain profitability and a sufficient return on capital
    with a relatively small percentage of market share. This advantage not only
    lowers our exposure to risk, but also gives us the flexibility to design our
    offerings to target a specific subscriber base of communications-intensive
    users without the requirement of necessarily attracting a large portion of
    the market. The ability to serve both business and residential customers
    also increases our potential overall market.

        Success-based Capital Expenditures -- An additional benefit of our Smart
    LEC network is the "success-based" cost structure of the capital
    expenditures. Conventional full-facilities networks typically require the
    network construction to be fully completed in advance of obtaining
    customers, generating high initial capital expenditures. Under our Smart LEC
    strategy, certain switch and access facilities are installed ahead of time,
    but the majority of capital is invested to increase the capacity of the
    network based on our success in attracting customers. We can therefore enter
    a market with a significantly lower up-front investment, and add facilities
    and leased capacity over time as we grow our customer base. A significant
    portion of our network expenses can therefore be incurred later and with
    more certain returns.

        Control of the Customer Experience -- We believe that having greater
    control over the services that we offer enhances our ability to improve the
    overall customer experience. Through the facilities which we install, we
    have control over the services provided to customers, including the
    operation of features, phone numbers, and line testing and servicing.
    Control over the implementation of the products enables us to better manage
    the service and to more easily offer custom packages of products and
    features. We believe that our delivery and marketing of targeted,
    customer-convenient, easy-to-understand packages differentiates us from our
    competition.

<PAGE>   592




        Ability to Serve Business and Residential Customers -- Our Smart LEC
    network architecture is designed to reach both business and residential
    customers. Because we are leasing rather than building the local connection
    to the customer, we believe we can economically reach the residential market
    despite its lower density relative to the business market. As a result, we
    are able to reach and serve the significant consumer segment, which has
    typically had significantly fewer competitors than the business segment. In
    addition, there are significant synergies which accrue from the ability to
    serve both business and residential market segments, including benefits to
    our marketing, service operations and network utilization.

        Higher Operating Margins -- We believe that deploying key network
    infrastructure will enable us to achieve significantly higher gross margins
    than the margins obtained under total service resale. Total service resale,
    which is the resale of complete services from ILECs without installing owned
    facilities, typically generates gross profit margins of approximately
    20-25%. Under the Smart LEC strategy, rather than reselling the entire
    service, we will be leasing only certain unbundled network elements, such as
    local loops and transport. We will use our own facilities for network
    interconnection, switching, features, and other network elements. By design,
    the facilities which we own and install are those which have a significant
    positive impact on our gross margins. By utilizing our own facilities for
    certain key portions of the network, we believe that we can increase our
    operating margins significantly above the margins which can be achieved with
    resale.

        Increased Speed to Market -- The Smart LEC strategy will also increase
    the speed at which we can enter additional markets. The time needed to
    construct a conventional network is extended by factors such as civil
    construction, the permit application process, certifications, and network
    management. Although constructing the Smart LEC network involves certain
    similar procedures, the majority of the installation work takes place in our
    own facilities and leased collocations of the ILECs, and significant route
    network construction elements are eliminated, which should contribute to an
    increased speed to market under our strategy. Whereas conventional networks
    typically take between 18 to 24 months to construct, we believe our networks
    can generally be installed in a 6 to 12 month time frame.

        Access to Wide Geographical Areas -- We believe the cost structure of
    the Smart LEC network will enable us to enter target areas which may not be
    economical for a full facilities network. When building a conventional
    network, density is a critical factor because the distance between the local
    switch and customers has a significant impact on build costs. In the Smart
    LEC network, although density is still important, it is less critical
    because the local loops are already built and are simply leased from ILECs.
    The ability to lease certain portions of the network therefore expands the
    potential territories that can be economically served by our network. In
    addition, we can offer total service resale in areas that are not yet served
    by our network, which expands our operating territory even further. Because
    ILECs are typically connected to all businesses and residences in its
    region, our ability to lease or resell these connections gives us
    considerable geographic flexibility and reach within our target markets. We
    believe that we will realize several advantages from having the ability to
    serve broad geographical areas, including operating synergies, marketing
    efficiencies and the enhancement of our overall company image presented to
    potential customers.

Network Development and Architecture

    Under our Smart LEC strategy, we build those portions of the network that we
believe will significantly increase our gross margins, are necessary to control
the services provided to the customer, and can be deployed rapidly and
efficiently. We lease those portions of the network that are readily available
to be leased economically from other providers. Accordingly, we are building the
Smart LEC network in each target market through a combination of the following
three central elements:

    o    Installing telephony and data equipment in our target metropolitan
         areas, including: Class 5 telephony switches, ATM switches and Internet
         point-of-presence equipment in our own facilities, along with telephony
         access devices, DSL access equipment, modems and other equipment in
         facilities collocated with the ILEC. These devices switch and route
         voice and data transmissions across the network.

    o    Leasing the "last mile" or "local loop" (the portion of the network
         extending from the end-office to the customer's premises). This local
         connection is leased by us from the ILECs as an "Unbundled Network
         Element" as provided under the Telecommunications Act of 1996. These
         local loops are used to transport voice and data services, for Internet
         access services, as well as for DSL and other high capacity voice and
         data applications. For larger customers or concentrated groups of users
         (such as multi-dwelling units), we lease circuits with greater
         bandwidth for this local connection.


                                       8


<PAGE>   593




    o    Leasing the transport capacity to carry voice and data both regionally
         (between our collocated facilities and our regional switch) and
         nationally (between our regional switches, our national Internet
         points-of-presence, other carriers, and the Internet). We lease these
         services from ILECs, Competitive Local Exchange Carriers (CLECs), Inter
         Exchange Carriers (IXCs), Competitive Access Providers (CAPs) and other
         providers. We use these leased circuits to transport our own voice and
         data traffic and deliver it to the most economical point of
         interconnection with other carriers. These leased circuits are
         interconnected using our national ATM facilities.

    As a complement to the network described above, we also resell complete
services from ILECs (total service resale). Although we intend to serve
customers primarily over our own network, resale allows us to expand our target
markets by adding service areas where our facilities are not yet installed. This
enables us to market our services prior to and during the installation of our
network, and then connect customers to our facilities once they are in place.
Resale also allows us to serve customers that may not be within the current
reach of our switch-based network. Although providing service on a resale basis
generates lower gross margins, we believe that there are advantages to offering
comprehensive geographical coverage within our target markets, particularly when
competing with an ILEC.

    We believe that the quantity of existing and planned fiber transport
facilities available from other carriers will be sufficient to satisfy our need
for leased transport facilities and permit us to obtain these facilities at
competitive prices for the foreseeable future. Several factors contribute to
this view: there is significant transport capacity in place today and we often
have the ability to choose from multiple providers including the ILECs; the
number of new providers building networks continues to increase; most providers
are consistently increasing their network capacity; and advances in wave
division multiplexing technology have continued to increase the capacity of
existing fiber plant. In addition, the ability to lease transport from the ILECs
gives us broad geographic coverage. As the volume of our traffic grows, however,
in the future it may become economical to build our own transport facilities in
certain markets.

    We currently lease transport capacity from multiple carriers across our
regional and national networks, including, among others:


               ILECs                       OTHER CARRIERS
               -----                       --------------

               US West                     Qwest

    Nationally, as we construct regional Smart LEC networks, our ATM network
will interconnect these local networks and other points-of-presence across the
U.S. over leased circuits to provide national data, voice and Internet
connectivity.

Network Technologies

    Our Smart LEC network is capable of carrying both voice and data
communications using the following technologies:

    o    Standard Telephony -- the traditional, reliable transmission of voice
         over local loop copper wire and regional and national fiber optical
         transmission path which, through the use of switches, becomes a
         dedicated end-to-end circuit.

    o    Internet Protocol (IP) -- the structure of data transmitted over the
         Internet. Because Internet Protocol involves splitting data into
         "packets" which are transmitted independently and reassembled at their
         destination, Internet Protocol does not require a dedicated end-to-end
         circuit and many different communications messages can be routed
         simultaneously over the same transmission facilities, resulting in
         greatly improved efficiency. This technology is currently being
         developed to be used reliably for voice service.

    o    Digital Subscriber Line (DSL) -- a transmission technology that allows
         for the transport of significant levels of voice and data at high
         speeds over conventional, copper phone lines. These higher transmission
         rates can be used for high-speed Internet access, to transport multiple
         voice lines over a single loop, or for both simultaneously.

    o    Asynchronous Transfer Mode (ATM) -- a transport protocol that supports
         many types of high-speed transmissions including voice, data, video,
         audio and imaging. ATM allows for the use of individual circuits for
         multiple simultaneous purposes, increasing network efficiency.


                                       9

<PAGE>   594




    o    Digital Loop Carrier (DLC) -- an access technology allowing us to
         aggregate and concentrate the voice traffic collected at the
         collocation facility to more efficiently transport this traffic to our
         switches.

Local and Regional Network Deployment

    We have identified six major metropolitan areas as the initial target
markets for the rollout of our regional Smart LEC networks. Our switches in
Columbus and Cleveland are currently active and we have begun provisioning our
residential and business customers that are on our footprint through these two
switches. Our Chicago switch has been installed, and we expect to begin
migrating customers in the second quarter of 2000. In addition, we are currently
constructing our network in three additional markets: Detroit, Michigan; New
York, New York; and Boston, Massachusetts. We expect the networks in these
markets to be installed in 2000. These six markets comprise approximately 18
million total access lines. We are in the process of establishing collocation
facilities in approximately 133 ILEC central offices in these markets. The
significant majority of these are physical collocations, under which we have
space within the central office that is dedicated to our exclusive use.

    We have also identified more than 30 additional markets where we intend to
deploy our Smart LEC network in 2000, 2001, and 2002. These markets are in
several states, including: Pennsylvania, Maryland, Connecticut, Indiana,
Wisconsin, Missouri, Florida, Texas and California, among others. The buildout
schedule, as well as the final selection of our markets, will depend on a number
of factors, including the success and speed of the rollout of the initial six
markets, ILEC interconnection agreements, and other factors. We will continue to
offer our Internet services nationally over our leased ATM network.

    Key data for our initial six markets is listed in the following table:

(3) We are in various stages of the collocation process depending on the market
    and its priority in our buildout schedule. Our collocation process consists
    of the following basic phases:

    o    Gathering of demographic data for each region and selection of specific
         ILEC facilities for collocation;

    o    Filing applications with the appropriate ILECs for collocation rights
         at each selected location;

    o    Upon receipt of each approval, doing an evaluation of each facility;

    o    Building by the ILEC of a "cage" or preparation of space in which our
         equipment will be placed; and

    o    Installing and testing of our equipment.

    We have at least obtained approval of our applications for all collocations
in progress.

    In determining our target markets, we prepare detailed analyses of
telecommunications and demographic data. Our target markets are chosen based on
a number of factors, including:

    o    Overall size of the telecommunications market;

    o    Concentration of business and residential customers;

    o    The availability of local transport networks and providers;

    o    Demographic statistics;

    o    The location of our existing resale customers;

    o    Our relationship with the ILEC and interconnection terms; and

    o    Regulatory environment.

    We are currently authorized to operate as a CLEC and/or long distance
telecommunications provider in 24 U.S. states.

    We believe that our Smart LEC strategy enables us to enter and construct our
network into new cities with relatively low up-front capital expenditures, and a
significant proportion of success-based capital expenditures. Depending on the
size of the market and other factors, our up-front costs to enter a market are
expected to be approximately $7 to $10 million, which includes initial set-up
costs associated with entering a market, such as the installation of our switch
and collocation facilities. Additional capital expenditures will be based on
subscriber levels and services offered and are estimated to be approximately
$400-$500 per line. Therefore, a significant portion of the total capital
expenditures in a given market will be incurred only as we increase our
subscriber base and the related capacity of the network.

National Network

    We currently have in place an ATM network which connects approximately 90
U.S. cities. We have facilities located in each of these points of presence, and
have leased DS-1 to OC-3 circuits to interconnect this network and to reach the
major national Internet access points. Approximately 49 owned ATM switches are
now being used across our network. The ATM switches allow us to carry multiple
services efficiently over our circuits. We directly peer with major backbone
providers including MCI WorldCom and PSINet. These peering arrangements help us
maintain a competitive low cost network. This national network interconnects our
local Smart LEC networks as they are deployed.

    Our national network currently interconnects our point-of-presence
facilities in the following cities:

Technology Management Center

    We opened our state-of-the-art Technology Management Center (TMC) during the
first quarter of 2000. The TMC monitors CoreComm's national facilities-based
network, including its Internet backbone. Using the latest network management
software, the TMC is able to provide real-time information to ensure network
reliability and instant network upgrades to meet consumer demand. The TMC houses
the latest in call routing and switching equipment for local and long distance
telephone services and features, and Digital Subscriber Line (DSL) technology.
The facility operates 24 hours, seven days a week and has a staff of 25
professionals.

The Telecommunications Act of 1996

    Our ability to lease unbundled network elements from incumbent providers is
the result of the Telecommunications Act of 1996. The Telecommunications Act
opened up the local telecommunications exchange market to competition, creating
an attractive opportunity for us and other carriers. The Telecommunications Act
requires that ILECs offer the use of their networks for total resale or the
lease of unbundled network elements, and that ILECs permit other carriers to
collocate and interconnect their equipment within the ILECs' central offices.
Moreover, an ILEC that is also a Bell operating company (BOC) is prohibited from
entering the long distance market in its home region until it is determined that
there is a significant level of competition in its local service market.


LMDS Broadband Wireless Spectrum

    As a complement to our Smart LEC network, we own Local Multipoint
Distribution Service (LMDS) licenses for the broadband wireless spectrum. Our
licenses cover nearly all of the state of Ohio and represent more than 10.5
million "POPs". With 1,150 MHz of spectrum, these licenses have much greater
bandwidth than cellular or PCS licenses (up to 30 MHz) or other fixed wireless
licenses (80-400 MHz). We are the fourth largest holder of this spectrum in
North America. NEXTLINK Communications, Inc. is the largest license holder, and
has licenses for major U.S. population centers outside of Ohio.

    LMDS is a newly authorized fixed broadband wireless service that may be used
to provide high-speed data transfer, telephone service, telecommunications
network transmission, Internet access, video broadcasting, video conferencing,
and other services. LMDS uses frequencies in the 28GHz to 31GHz range. The
spectrum is useable for communication services from a fixed antenna, but is not
suitable for mobile or portable communications. The service is subject to line
of site limitations and rain attenuation, but current systems seek to reduce
these impediments through advanced system architecture and the strategic
placement of transmitters. The point-to-multipoint technology of LMDS allows a
single hub site antenna to be used to form multiple paths with customer antennas
at numerous locations. LMDS can thus be used to provide a wireless high-capacity
broadband service for the "last mile" to a subscriber's home or office.

    As LMDS technology advances, we intend to use this spectrum to offer
additional communications services and to expand the reach of our network. For
some locations, we believe that LMDS may offer a substantially lower cost
solution for providing high-quality broadband services than other competing
delivery systems such as fiber or copper extensions. LMDS equipment is not in
general commercial service at this time, but technology is currently in
development and we have established relationships with several equipment
vendors.

    Through a wholly owned subsidiary, in June 1998, we were awarded A-Block
licenses in 15 markets in Ohio with a total of 10,573,982 POPs (representing
more than 95% of the POPs in Ohio). Each LMDS license covers a defined Basic
Trading Area, and our A-Block LMDS licenses consist of 1,150 MHz of spectrum.
CoreComm bid $25.2 million for such licenses, for an average of $2.39 per POP.
POPs are the estimated population of a market. The number of POP's owned by an
operator does not represent the number of users of its services and is not
necessarily indicative of the number of potential subscribers.


PRODUCTS AND SERVICES

    We currently offer our business and residential customers an extensive array
of voice and data services in order to satisfy and capture all of their
communications needs.

Bundled Packages

    In our current service offerings, we bundle communications products and
services in order to give our customers increased convenience, flexibility and
choice, at good "value for money." We typically offer a platform of basic
services, which represents a minimum selection of services to be offered, and
then create ways for the customers to easily and conveniently increase the other
services purchased according to their tastes.


                                       12

<PAGE>   597




    For example in our current residential offering, we combine a basic package
of voice services with Internet access, which we call the "e-Chat" service.
Under the e-Chat service, customers are offered a bundled package of
communications services that includes local, long distance and Internet service.
Although the details of the offerings vary somewhat by region, the service
typically includes:

    o    Local dial tone

    o    Local calls

    o    Call waiting

    o    Caller-ID

    o    Personal "800" number

    o    Premium Internet Service

         o    56K unlimited access

         o    5 e-mail accounts

         o    personal web space

    o    Long distance service option (10 cents per minute)

    Additional options and features (such as voice mail, three-way calling, an
additional line, and additional web site space) can be easily and flexibly added
to the service. The pricing for e-Chat varies by region, but in all areas our
price is based on the exact retail pricing from the RBOC for the same local
telephony services.

    This marketing strategy has been based on the successful experience of
management in penetrating the residential market and competing with incumbent
operators in its other communications companies. We believe that this type of
marketing strategy has many benefits for both potential customers and CoreComm.

    We believe that potential customers will be attracted to the simplicity of
both how we offer and price the service, and of having consolidated services
with one provider on one invoice. In addition, we believe that our proposition
will be viewed as good "value for money". For the same price that customers
currently pay the incumbent operator for telephone alone, from CoreComm they can
get the same telephone service, plus Internet access. We price the service at
the same rates as the RBOC's telephone service so that it can be perceived
simply, easily and quickly as a valuable service. The ability to add additional
features conveniently enhances the overall flexibility, and allows customers to
tailor the service for their individual needs.

    In addition, we believe that these types of bundled services will improve
our operating results. The structure and strategy of our residential product
offerings will have a significant impact on our ability to penetrate our target
markets successfully. We believe that bundled offerings like our e-Chat service
will be attractive to potential customers. In addition, we believe bundled
packages improve customer retention because customers typically must approach
multiple providers in order to replace the bundled CoreComm services. Finally,
we believe that combining a feature-rich telephony service with Internet access
service will attract communications-intensive users, who typically generate
higher average revenue and are more likely to subscribe to additional
communications services, such as high speed access.

    Although the specific components of our offerings will change, we will
continue our strategy of designing attractive marketing packages which give the
customer flexibility and choice, with convenient ways to subscribe to additional
services.

Voice and Data Services

    We currently offer the following voice, data and Internet services to
business and residential customers in our markets:

    o    Local Exchange Services -- including standard dial tone, local calling,
         Centrex services, Emergency 911 services, operator assisted calling,

    o    Web Site Hosting and Design -- including dedicated and shared site
         hosting and, typically through third parties, web site design.

    o    Data Networking Services -- including a variety of data circuits and
         networking solutions.

DSL Offering

    DSL is a transmission technology that allows for the high speed transport of
significant levels of voice and data over conventional, copper phone lines. DSL
can deliver speeds of up to 7 Mbits per second, which is the equivalent of more
than 100 voice grade circuits, over a single copper loop.

    DSL technology enables consumers to transfer data or access the Internet at
high speeds. In addition to significantly increasing data transfer rates, DSL
technology offers an alternative for providing multiple voice lines or voice and
data carried over the same pair of twisted copper wire. By using DSL, businesses
can obtain the same number of voice lines over a single loop that would normally
be obtained using a more expensive standard T1 or other circuit. DSL technology
also makes it possible for business or residential customers to obtain telephone
service and high-speed data service simultaneously over a standard copper
telephone line.

    We believe there are several benefits to DSL, including:

     o   High bandwidth, high-speed, "always on" Internet connections;

     o   Dedicated, not shared bandwidth, which allows for "guaranteed"
         performance levels;

     o   Ratable service, which allows us to tailor the service to the
         customers' needs and allows the customers to determine how much money
         to expend for the amount of high speed bandwidth they need;

     o   Ability to use the same loop for voice and data simultaneously;

     o   Enhanced security;

     o   Utilization of existing copper infrastructure, which allows faster
         rollout and lowers deployment costs;

     o   Increased telephony margins as a result of providing multiple services
         over a single local loop; and

     o   Deployment with success-based capital expenditures.

    We believe our Smart LEC network is well suited to capitalize on DSL
technology. In our own switch facilities and our collocation facilities, we are
deploying DSL access equipment (including DSLAMs). DSLAMs are connected to the
copper loops at the end office, and aggregate and concentrate the data traffic
from the end user. DSL technology is limited by the length of the loop being
used, which typically must be less than three miles, as well as other factors
such as the condition and quality of the copper line. We rollout our DSL network
and services simultaneously with the telephony network. We use DSL to provide
high-speed Internet access and data services and intend to use DSL to provide
combined data and voice services over a single copper loop, and voice circuit
trunking to connect multiple access lines.

    We deploy multiple forms of DSL in order to provide a broad service offering
to our customers and to expand the DSL coverage of our target markets. Our
offerings include different forms of Asymmetric DSL (ADSL) including Rate
Adaptive DSL (RADSL), Symmetric DSL (SDSL) and Integrated DSL (IDSL). Our ADSL
offering is expected to include G.lite as well. We believe that a widely
accepted standard, such as G.lite, will enhance our ability to penetrate our
target markets with DSL services.

Other Related Services

    Cellular and Paging Services. As a complement to our voice and data
services, we also offer cellular and paging services. Although these are not
core products and do not utilize our own networks, they are offered as an
additional service for our business and residential customers for added choice
and convenience. We are currently offering cellular services in Ohio and
Michigan, and may choose to add other markets in the future. Our paging service
is available nationally. We have resale agreements with the three major
providers of cellular service in Michigan and Ohio: AirTouch Cellular, GTE
Mobilenet Inc. and Ameritech Mobile Communications, Inc. In addition, we sell
retail cellular long distance telephone services to cellular customers of
various local cellular service providers who have chosen us as their long
distance service provider.

    IP Telephony. With recent advancements in the development of telephony
equipment using Internet Protocol, the overall quality of telephone calls
delivered over an IP network has become increasingly reliable and has become
more equivalent to the circuit-switched network. Although we are not currently
using this technology to deliver our voice traffic, our local and national
networks have been designed to allow for the use of IP telephony when and if
reliable technology becomes available.

    Under this technology, our platform would compress and convert voice into IP
packets using voice compression algorithms, digital signal processors and
ancillary software. These packets would then be transmitted via our national IP
network. Due to its scalability and compression features, this technology would
allow a greater quantity of simultaneous voice calls and data to be carried over
the network compared to traditional circuit switching, thus utilizing
significantly less bandwidth. Potential services offered under this technology
would include local and long distance calling, fax transmission, call
termination, national voicemail, and other related services.

SALES AND MARKETING

    Our marketing strategy is to provide business and residential customers a
bundled package of high quality telecommunications services, delivered with
quality care and service to the customer at prices which offer "value for the
money".

    In its prior experience, our management has had significant success in
marketing integrated communications products in several other operations both in
the U.S. and abroad. We believe much of this success was due to our management's
ability to creatively and effectively design and market integrated
communications products and services. We intend to capitalize on this experience
to develop service offerings to attract and retain business and residential
customers in our target markets.

    A core part of our strategy is to offer our customers bundled
telecommunications, Internet and data services. Our integrated service offerings
are packaged and priced to give the customer increased flexibility, choice, and
value, while also enhancing convenience. Our offerings can be created to allow
flexibility to meet individual customer needs, and are conveniently offered on a
single bill. We believe that offering combined packages of local and long
distance telephony, Internet access and data services is attractive to the
potential business and residential customers in our target markets. In addition
to attracting customers, we believe this strategy also improves our
profitability by increasing average revenue per customer, reducing customer
acquisition costs and other operating costs, and improving customer retention.

    The broad reach of the Smart LEC network enables us to market our services
over wide geographical areas. By using a combination of resold and switch-based
services, we are not limited to offering services only in areas where we have
built our own networks. We capitalize on our ability to market over wide areas
by utilizing mass marketing strategies and other efficient methods of
communicating with our potential customer base. For example, we have contracted
to be one of only four gate sponsors for the new football stadium for the
Cleveland Browns. Under this agreement, we have prominent placement of
advertisements throughout the stadium, an entry gate known as the CoreComm Gate,
game giveaway opportunities, and other related advertising benefits. The broad
reach of our network across the Cleveland area allows us to take advantage of
such mass market opportunities. We believe that these and other initiatives will
increase the awareness of the CoreComm brand and will attract new business and
residential customers in our target markets. We believe that the ability to
market over larger areas increases the efficiency and effectiveness of our
marketing and advertising programs.

    In the business market, we focus on a direct sales approach, targeting small
and medium-sized businesses. We believe that small to medium-sized businesses
represent a large and growing market which is currently undeserved by the ILECs
and competitive providers. We seek to attract these target customers with
customer-convenient bundles, providing simplicity, flexibility and ease of
decision-making. We use our sales force to sell directly to customers, to
establish a relationship with telecoms managers, and to better understand and
service their communications needs. We generally employ sales people with
significant experience in the telecommunications industry. In order to
effectively incentivize our sales force, a large portion of their compensation
is performance-based and focused on sales and customer retention. We try to
attract and retain qualified sales people by offering them the opportunity to
work with a successful management team in an entrepreneurial environment, with
equity participation through stock options.

CUSTOMER INTERFACE AND PROPRIETARY SYSTEMS

    We believe that the customer experience must be easy, enjoyable, and
exceptional. We have developed integrated systems and procedures that will
substantially support all aspects of our business, including provisioning,
billing, customer care and collections. Our information services and customer
care operations are closely linked to ensure that all related operations are
effectively integrated. We believe this focus on the customer experience will
provide us with a competitive advantage in attracting and retaining customers.

"Internet Centric" Approach

    We are in the process of actively developing and incorporating systems to
deliver "Internet Centric" operational support systems. These customer-facing
systems are expected to add functionality in the areas of electronic billing,
web-based customer care and e-commerce. We are preparing to support a
substantial portion of our customer interactions over the World Wide Web. Our
customers are able to order new services and interact with our customer care
department without using the telephone. They will also be able to view and pay
their bill online. We believe that this method of communicating with the
customer will not only be convenient for the customer, but will also increase
our operating efficiency.

    We employ a variety of techniques to effectively and efficiently serve the
customer, including:

    Efficient Fulfillment of Services -- Our systems support electronic tracking
    of orders from provisioning through installation. Service orders will flow
    directly from the consumer to our back office, and then on to the ILEC.
    Administrative controls in our support systems are designed to provide
    timely identification and resolution of customer concerns and issues.

    Low-cost Billing -- We have developed a customer friendly, fully integrated
    billing statement covering all of the communications services supplied. The
    statement currently can be delivered electronically via e-mail. Customers
    may elect to pay their bill automatically via credit card or direct debit.
    We are further developing web-based electronic bill presentment and payment
    capabilities. These services will reduce billing costs while providing
    value-added services to customers such as the ability to sort billing data
    and create customized reports.

    Smart Customer Care -- We intend to continue to develop sophisticated
    customer care systems that will increase our use of the Internet as a means
    of communicating with our customers. We are currently making customer care
    available via e-mail, which allows for simple requests and changes to be
    processed without use of the phone and for customer care associates to work
    from outside of our facilities. We are currently expanding our web-based
    care services to include significant additional functionality. These and
    other initiatives are expected to improve the efficiency of our customer
    care resources by developing on-line tools which will enable customers to
    communicate more efficiently with us and even service themselves when
    appropriate.

Electronic Bonding & Proprietary Systems

    We view the efficiency and the accuracy of our communications and interface
with ILECs as an important strategic priority. We are currently bonded
electronically with Ameritech and Bell Atlantic. This electronic interface
allows for more timely and accurate service ordering and provisioning of our
customers. We have real-time access to customer information as well as real-time
order entry and confirmation. We provision service to customers through our
proprietary systems, which are designed to interface with the ILECs' systems
through a variety of delivery mechanisms. Our systems and processes have been
developed to decrease the risk of human error associated with provisioning
customers by manual keying or fax.

    Our customer interface systems have been developed and continue to be
enhanced in a client/server environment that allows for flexibility to
accommodate an expanding customer base, efficient entry into new markets,
switch-based services, and rapid development of additional functionality. Our
proprietary systems handle all pre-ordering activities, including obtaining
customer service records (CSR), finding and reserving telephone numbers,
verifying customer addresses, validating due dates, searching the ILEC's
switches for feature availability (COFA), and yellow page listings.

    In addition, we have developed proprietary methods of ordering and
provisioning services through ILECs by formatting and sending electronic data
interchange (EDI) messages. These systems use common software for the actual
sending and receiving of purchase orders and acknowledgements, but use custom
code for the content of these messages. We typically use off-the-shelf software
for standard processes that is readily available, and develop proprietary
systems when such processes need to be modified to meet our needs.

System Enhancements

    Given the importance that we place on the efficiency, quality and scale of
our back office capabilities, we continuously upgrade our proprietary systems in
order to enhance their functionality and performance. Our recent and ongoing
enhancements to our information systems include the following:

     o     Our Rating and Billing engines are being re-engineered for
           performance and scalability using a multi-tiered architecture.

     o     Our provisioning systems for the Ameritech region have been enhanced
           to support Ameritech's five state region. Our service order
           management system has been enhanced to validate in real time the ILEC
           feature availability, integrate the electronic generation of service
           order data, and integrate automated switch activation software for
           our Class 5 switches, all within a single system. The provisioning
           information is entered once, and it flows through our internal
           systems, our switch, and the ILEC systems without any manual
           processes.

     o     We have evaluated best of breed Interconnection Gateway packages that
           will allow us to develop further electronic bonding with all future
           ILECs in our business plan going forward, and are planning for the
           integration with our current back office systems later this year.

     o     We have automated the migration processes to move customers from
           resale to "on-net" via our service order management system, which has
           been designed to eliminate any manual processes with the ILEC.

     o     We have purchased and installed a platform for our call centers which
           has introduced skills-based routing of our inbound calls with our
           automated attendant. This allows us to service our customers better
           by ensuring that a call is delivered to a customer service
           representative with the skills necessary to handle the customer.

     o     We have integrated a new auto-dialer with our collections system,
           which has significantly increased collection agent productivity and
           effectiveness.

COMMUNICATIONS INDUSTRY

    We are participating in the large and rapidly changing U.S. wireline
telecommunications industry. We believe that the wireline telecommunications
industry benefits from positive price elasticity, as well as growing,
non-cyclical demand for services. According to the U.S. Census Bureau, the total
market size of the telecommunications services industry (which excludes cable
television and Internet access) has increased from approximately $160 billion in
1990 to approximately $285 billion in 1998. This represents growth of 78% over
this period. The wireline segment of this market accounts for approximately $208
billion, or 73% of the total telecommunications services market in 1998.
Approximately 50% of wireline segment revenues are derived from local service
and network access.

    According to FCC data, the total local revenue generated by the CLECs and
competitive access providers was less than 2.5% of the total U.S. local revenues
in 1998. As of June 30, 1999, CLEC lines (resold and switched) constituted
approximately 2.6% of the total switched lines in the U.S.

    The emergence of the Internet and demand for data services has had a
significant effect on the U.S. communications industry. The use of the Internet
in both businesses and residences has been increasing rapidly, and is expected
to continue its growth. Forrester Research projects that revenues from Internet
access services will grow from $10.3 billion in 1998 to $61.8 billion in 2003 in
the U.S. They also project that web hosting revenues will increase from $900
million in 1998 to $14.7 billion in 2003 in the U.S. Frost and Sullivan project
that the total U.S. market for high-speed and switched data services will grow
at an annual rate of approximately 17%, from $18.0 billion in 1997 to
approximately $40 billion by 2002. The Gartner Group forecasts data traffic to
grow more than five times faster than voice traffic through 2002, and that DSL
revenue will grow at an annual rate of over 200% from 1998 to 2003, to reach
$18.0 billion.

    We believe the overall size and growth of the U.S. communications market
presents a significant opportunity for competitive communications providers.
There are several factors which we believe will enhance the ability for
competitive providers to compete with the incumbent operators, including general
market receptivity to alternative providers, the desire in the business market
to diversify services to multiple suppliers, and the ability of competitive
providers to attractively bundle services and to offer improved customer
service.

OUR OTHER BUSINESSES

    We are exploring other telecommunications opportunities both domestically
and internationally, including other facilities-based telecommunications
businesses and prepaid cellular telephone service opportunities.

COMPETITION

    The telecommunications industry and all of its segments are highly
competitive and many of our existing and potential competitors have greater
financial, marketing, technical and other resources than we do. Please refer to
the section entitled "Risk Factors--We face heavy competition in the
telecommunications industry for all of the services we currently provide and
those we intend to provide in the future." Competition for our products and
services is based on price, quality, network reliability, service features and
responsiveness to customers' needs.

CLEC

    In each of our markets, we face competition from ILECs, including Ameritech
and Bell Atlantic, as well as other providers of telecommunications services,
such as GTE, other CLECs and cable television companies. In the local exchange
markets, our principal competitor will be the ILECs. We also face competition or
prospective competition from one or more CLECs. For example the following
companies have each begun to offer local telecommunications services in major
U.S. markets using their own facilities or by resale of the incumbent local
exchange carrier's services or other providers' services: AT&T, MCI WorldCom,
ICG, NEXTLINK and Sprint.

    Some of our competitors, including AT&T, MCI WorldCom and Sprint, have
entered into interconnection agreements with Ameritech in states in which we
operate. These competitors either have begun or in the near future likely will
begin offering local exchange service in those states. In addition to these long
distance service providers and existing CLECs, entities that currently offer or
are potentially capable of offering switched telecommunications services
include:

    o    wireless telephone system operators;

    o    large customers who build private networks;

    o    cable television companies; and

    o    other utilities.

    Competition in our CLEC business will continue to intensify in the future
due to the increase in the size, resources and number of market participants.
Many facilities-based CLECs have committed substantial resources to building
their networks or to purchasing CLECs or IXCs with complementary facilities. By
building or purchasing a network or entering into interconnection agreements or
resale agreements with ILECs, including Regional Bell Operating Companies
(RBOCs) and IXCs, a provider can offer single source local and long distance
services similar to those offered by us. Such additional alternatives may
provide such competitors with greater flexibility and a lower cost structure
than us. Some of these CLECs and other facilities-based providers of local
exchange service are acquiring or being acquired by IXCs. These combined
entities may provide a bundled package of telecommunications products, including
local and long distance telephony, that is in direct competition with the
products offered or planned to be offered by us.

    Under the Telecommunications Act and related federal and state regulatory
initiatives, barriers to local exchange competition are being removed. The
availability of broad-based local resale and introduction of facilities-based
local competition are required before the RBOCs may provide in-region long
distance services originating in their traditional service area. The RBOCs are
currently allowed to offer certain in-region "incidental" long distance services
(such as cellular, audio and visual programming and certain interactive storage
and retrieval functions) and to offer out-of-region landline long distance
services.

    Section 271 of the Telecommunications Act prohibits an RBOC from providing
long distance service that originates (or in certain cases terminates) in one of
its in-region states until the RBOC has satisfied certain statutory conditions
in that state and has received the approval of the FCC. The FCC to date has
granted only one RBOC 271 application, which was filed by Bell Atlantic in New
York. It is currently reviewing an application filed by SBC for Texas. We
anticipate that RBOCs, including Bell Atlantic and SBC/Ameritech, will file
additional applications for in-region long distance authority in other states.
The FCC will have 90 days from the date an application for in-region long
distance authority is filed to decide whether to grant or deny the application.
Once the RBOCs are allowed to offer widespread in-region long distance services,
they will be in position to offer single-source local and long distance services
similar to those offered by CoreComm and the largest IXCs.


                                       18

<PAGE>   603




    While new business opportunities have been made available to us through the
Telecommunications Act and other federal and state regulatory initiatives,
regulators are likely to provide the ILECs with an increased degree of
flexibility with regard to pricing of their services as competition increases.
If the ILECs elect to lower their rates and sustain lower rates over time, this
may adversely affect our revenues and place downward pressure on the rates we
can charge. We believe the effect of lower rates may be offset by the increased
revenues available by offering new products and services to our target customers
as well as increased usage, but we cannot be sure that this will occur. In
addition, future regulatory decisions may afford the ILECs excessive pricing
flexibility or other regulatory relief which could have a material adverse
effect on us.

INTERNET

    The Internet services market is also extremely competitive. We compete
directly or indirectly with the following categories of companies:

    o    established online services, such as America Online, the Microsoft
         Network and Prodigy;

    o    local, regional and national ISPs, such as Earthlink/MindSpring and
         Internet America;

    o    national telecommunications companies, such as AT&T and MCI;

    o    RBOCs, such as Ameritech and Bell Atlantic; and

    o    online cable services, such as Excite@Home and Roadrunner.

    This competition will increase as large diversified telecommunications and
media companies acquire ISPs and as ISPs consolidate into larger, more
competitive companies. Diversified competitors may bundle other services and
products with Internet connectivity services, potentially placing us at a
significant competitive disadvantage. As a result, our businesses may suffer.

    Our DSL service offering will also face competition from the traditional
telephone companies, cable modem service providers, competitive
telecommunications companies, traditional and new national long distance
carriers, other Internet service providers, on-line service providers and
wireless and satellite service providers.

LMDS

    Depending on the services ultimately offered, our LMDS business could face
the same competition as outlined above. In addition, the extent it is used to
deliver pay television, our LMDS business will compete with franchised cable
television systems and also may face competition from several other types of
Multichannel Video Programming Distributors (MVPDs) including:

    o    Multichannel Multipoint Distribution Systems;

    o    Satellite Master Antenna Television Systems;

    o    DBS and other television receive-only satellite dishes;

    o    video service from telephone companies; and

    o    open video system operators.

    MVPDs face competition from other sources of entertainment, such as movie
theaters and computer on-line services. Further, premium movie services offered
by MVPDs have encountered significant competition from the home video industry.
In areas where off-air television broadcasts can be received without the benefit
of terrestrial distribution systems, MVPDs have experienced competition from
such broadcasters. Online services and ISPs also serve as a source of
competition to MVPDs.

    The Telecommunications Act relaxed the regulatory barriers to entry by ILECs
into the provision of video programming in their local telephone service areas,
and it substantially reduces current and future regulatory burdens on franchised
cable television systems, thus potentially resulting in significant additional
competition to LMDS operators from local telephone companies and franchised
cable television systems.


                                       19

<PAGE>   604




OTHER BUSINESSES

    In addition to our CLEC, Internet and LMDS businesses, our other businesses
face strong competition as well. These competitive businesses include long
distance service, cellular service and paging service. Our long distance service
faces competition from long distance carriers, including facilities-based
carriers such as AT&T, MCI WorldCom and Sprint and resellers of long distance
service. Our cellular service faces competition from other cellular carriers,
such as Vodafone AirTouch and AT&T, and from PCS carriers, such as Sprint PCS.
Our paging services are similarly exposed to competition from other providers of
paging services operating in the same local markets, regionally or nationally.

CUSTOMER DEPENDENCE AND SEASONALITY

    We do not depend upon any single customer for any significant portion of our
business. Neither our business nor the telecommunications industry are generally
characterized as having a material seasonal element, and we do not expect our
business or the industry to become seasonal in the foreseeable future.

RECENT DEVELOPMENTS

AGREEMENT TO ACQUIRE ATX TELECOMMUNICATIONS SERVICES, INC.

    On March 10, 2000, we announced that we had entered into a definitive
agreement to acquire ATX Telecommunications Services, Inc. ("ATX"), which is a

The transaction is subject to regulatory and shareholder approval and other
customary closing conditions.

AGREEMENT TO ACQUIRE VOYAGER.NET, INC.

    On March 13, 2000, we and Voyager.net, Inc. ("Voyager.net") announced that
we had entered into a definitive agreement through which we would acquire
Voyager.net for shares of our common stock and cash. Voyager.net is the largest
independent full-service Internet communications company in the Midwest, and is
rapidly expanding into DSL delivery of its services. Under the agreement,
Voyager.net shareholders will receive 0.292 shares of our common stock and $3 in
cash for each share of Voyager.net common stock (an aggregate of approximately
9.2 million shares and approximately $95 million in cash). Under the agreement's
collar provisions, the shares of common stock issued will be reduced if our
common stock price at closing exceeds $57 per share, and increased if our common
stock price at closing is below $41 per share. If our stock price at closing is
below $33 per share, there would be no further adjustment to the number of
shares of our common stock issued and Voyager.net will have the right to
terminate the transaction, subject to our right to adjust further the shares
issued. The transaction is subject to regulatory and shareholder approval and
other customary closing conditions. Holders of over a majority of the voting
shares of Voyager.net have entered into an agreement with us to vote in favor of
the transaction.

OFFERING OF CORECOMM CONVERTIBLE NOTES

    On October 6, 1999, we closed our sale of $175 million of 6% Convertible
Subordinated Notes, due 2006 (the "Convertible Notes"). The Convertible Notes
were sold only in transactions exempt from or not subject to the registration
requirements of the Securities Act of 1933, as amended. The Convertible Notes
are convertible into shares of our common stock at a conversion price of $27.39
per share. Pursuant to a registration rights agreement, we have registered with
the Securities Exchange Commission the Convertible Notes and shares of common
stock issuable upon conversion of the Convertible Notes.

CORECOMM STOCK SPLITS

    In August of 1999, our board of directors approved a 3-for-2 stock split,
payable as a stock dividend. The record date and the payment date for the stock
split were August 30, 1999 and September 2, 1999, respectively. In January 2000,
our board of directors approved another 3-for-2 stock split, also payable as a
stock dividend. The record date and the payment date of the second stock split
were January 28, 2000 and February 2, 2000, respectively. For both stock splits,
one new share of our common stock was distributed for each two shares of our
common stock owned on the record date for the stock split, with fractional
shares rounded up or down. All common stock and per share data have been
adjusted to reflect the stock splits.

EMPLOYEES

    As of December 31, 1999, we had an aggregate of approximately 850 employees.
None of our employees are represented by any labor organization. We believe that
our relationship with our employees is excellent.

OPTION PLANS

    In 1998, our Board of Directors adopted the CoreComm Limited 1998 Stock
Option Plan and in 1999, our Board of Directors adopted the CoreComm Limited
1999 Stock Option Plan, reserving under these plans shares for issuances to
employees and directors.

    The purpose of our stock option plans is to encourage stock ownership by our
employees and non-employee directors, and the employees and non-employee
directors of our divisions, subsidiary corporations and other affiliates, so as
to encourage our employees to continue being employed by us and to put forth
maximum efforts for the success of our business. Under our stock option plans,
grants may be made of options to acquire shares of our common stock. The options
may be "incentive stock options" within the meaning of Section 422 of the
Internal Revenue Code. The terms of options granted under our stock option
plans, including provisions regarding vesting, exercisability, exercise price
and duration, are generally set by the Compensation Committee of our Board of
Directors. In general, options under our plans are 20% vested at grant and vest
20% each January 1 after they are granted, until they are fully vested.

    In January 1999, CoreComm, Inc., one of our wholly-owned subsidiaries,
adopted a stock option plan. Options granted under that plan were not to become
excercisable unless and until there was either a registered public offering of
CoreComm, Inc.'s common stock or a spin-off of CoreComm, Inc. However, pursuant
to the terms of the options granted under that plan, we reserved the right to
cancel the plan and issue new options in the parent company, CoreComm Limited.
In March 2000, the Compensation and Option Committee of our Board of Directors
approved the cancellation of the CoreComm, Inc. plan and the issuance of options
in CoreComm Limited to eligible employees of CoreComm, which will result in the
issuance of options to purchase approximately 2.7 million shares of CoreComm
Limited common stock. The strike prices of the new grants are approximately 30%
of the fair market value of our common stock on the date of the new grant.
Eligibility for receiving the new grants is determined by, among other things,
continued employment with CoreComm.


                                   REGULATION

OVERVIEW

    The telecommunications services we provide are subject to regulation by
federal, state and local government agencies. The following summary does not
purport to describe all current and proposed regulations and laws affecting the
telecommunications industry. Other existing federal and state regulations and
legislation are the subject of judicial proceedings, legislative hearings and
administrative proposals, which could change in varying degrees the manner in
which this industry operates. Neither the outcome of these proceedings nor their
impact on the telecommunications industry or our business can be determined at
this time. Future federal or state regulations and legislation may be less
favorable to us than current regulation and legislation and therefore may have a
material and adverse impact on our business and financial prospects. In
addition, we may expend significant financial and managerial resources to
participate in proceedings setting rules at either the federal or state level,
without achieving a favorable result.

    At the federal level, the FCC has jurisdiction over interstate and
international services and interstate services are communications that originate
in one state and terminate in another. Intrastate services are communications
that originate and terminate in a single state and state public service
commissions exercise jurisdiction over intrastate services. Municipalities and
other local government agencies may also regulate limited aspects of our
business, such as use of government-owned rights-of-way and construction
permits. Our networks are also subject to numerous local regulations such as
building codes, franchise and right-of-way licensing requirements.

TELECOMMUNICATIONS ACT OF 1996

    The federal Telecommunications Act, enacted in 1996, has resulted and will
continue to result in substantial changes in the marketplace for
telecommunications services. These changes include, at present, opening local
exchange services to competition and, in the future, a substantial increase in
the addressable services for us. Among its more significant provisions, the
Telecommunications Act:

       o   removes legal barriers to entry into all telecommunications services,
           such as long distance and local exchange services;

       o   requires ILECs (e.g., Ameritech or Bell Atlantic) to "interconnect"
           with and provide  services for resale by
           competitors;

       o   establishes procedures for LECs and BOCs to enter into new services,
           such as long distance and cable television;

       o   relaxes regulation of telecommunications services provided by ILECs
           and all other telecommunications service providers; and

       o   directs the FCC to establish an explicit subsidy mechanism for the
           preservation of universal service.

    The FCC was also directed by Congress to revise and make explicit subsidies
inherent in the access charge paid by IXCs for use of local exchange carriers'
services.

REMOVAL OF ENTRY BARRIERS

    The provisions of the Telecommunications Act should enable us to provide a
full range of local telecommunications services in any state. Although we will
be required to obtain certification from state public service commissions in
almost all cases, the Telecommunications Act should limit substantially the
ability of a state public service commission to deny a request for
certification. The provisions of the Telecommunications Act also reduce the
barriers to entry by other potential competitors and therefore increase the
level of competition we will likely face in all markets affected by the Act.
Please refer to the section entitled "Business--Competition."

INTERCONNECTION WITH LOCAL EXCHANGE CARRIER FACILITIES

    A company cannot compete effectively with the ILECs in the switched local
telephone services market unless it is able to connect its facilities with the
ILEC's facilities and obtain access to certain essential services and resources
under reasonable rates, terms and conditions. The Telecommunications Act imposes
a number of access and interconnection requirements on all local exchange
providers, including CLECs, with additional requirements imposed on non-rural
ILECs. These requirements are intended to provide access to certain networks
under reasonable rates, terms and conditions. Specifically, ILECs must provide
the following:

    UNBUNDLING OF NETWORK ELEMENTS. ILECs must offer access to various unbundled
elements of their network. This requirement allows new entrants to purchase at
cost-based rates elements of an ILEC's network that may be necessary to provide
service to a new entrant's customers.

    DIALING PARITY. All local exchange carriers must provide dialing parity,
which means that a customer calling to or from a CLEC network cannot be required
to dial more digits than is required for a comparable call originating and
terminating on the ILEC's network.

    TELEPHONE NUMBER PORTABILITY. Telephone number portability enables a
customer to keep the same telephone number when the customer switches local
exchange carriers.

    RECIPROCAL COMPENSATION. The duty to provide reciprocal compensation means
that local exchange carriers must terminate calls that originate on competing
networks in exchange for a given level of compensation and that they are
entitled to termination of calls that originate on their network, for which they
must pay a given level of compensation.

    RESALE. All local exchange carriers generally may not prohibit or place
unreasonable restrictions on the resale of their services. In addition, ILECs
must offer local exchange services to resellers at a wholesale rate that is less
than the retail rate charged to end users.


                                       22

<PAGE>   607






    COLLOCATION. ILECs must permit CLECs to install and maintain their own
network equipment in ILEC central offices and remote terminals subject to
certain rates, terms and conditions.

    ACCESS TO RIGHTS-OF-WAY. All ILECs, CLECs and certain other utilities must
provide access to their poles, ducts, conduits and rights-of-way on a
reasonable, nondiscriminatory basis.

    ILECs are required to negotiate in good faith with other carriers that
request any or all of the arrangements discussed above. If a requesting carrier
is unable to reach agreement with the ILEC within a prescribed time, either
carrier may request arbitration by the applicable state commission.

    The rates charged by ILECs for interconnection and unbundled network
elements vary greatly from state to state. These rates must be approved by state
regulatory commissions, which often follows a lengthy and expensive negotiation,
arbitration, and review process. Recurring and non-recurring charges for
telephone lines and other unbundled network elements may change based on the
rates proposed by ILECs and approved by state regulatory commissions from time
to time, which could have an adverse effect on our operations. In addition, the
FCC's cost- based methodology for determining these rates is still subject to
judicial review, which creates uncertainty about how interconnection and
unbundled element rates will be determined in the future.

    While the Telecommunications Act generally requires ILECs to offer
interconnection, unbundled network elements and resold services to CLECs,
ILEC-to-CLEC interconnection agreements may have short terms, requiring the CLEC
to renegotiate the agreements. ILECs may not provide timely provisioning or
adequate service quality, thereby impairing a CLEC's reputation with customers
who can easily switch back to the ILEC. In addition, the prices set in the
agreements may be subject to significant rate increases if state regulatory
commissions establish prices designed to pass on to the CLECs part of the
intrastate cost of providing universal service.

    In January 1999, the United States Supreme Court upheld the FCC's authority
to adopt pricing rules for interconnection services, unbundled network elements,
and resale by CLECs. However, the Supreme Court instructed the FCC to reconsider
aspects of its 1996 order regarding the extent to which ILECs are required to
unbundle elements of their networks. The FCC's pricing rules are still subject
to further judicial review. On remand from the Supreme Court, the FCC adopted an
order on September 15, 1999, which specified the unbundled elements that ILECs
must make available to competitors. The FCC reaffirmed that incumbents must
provide unbundled access to six of the seven network elements that were listed
in the FCC's 1996 order. According to the FCC, the seventh item, operator and
directory assistance services, are no longer necessary to permit competition.
The FCC's order also added additional unbundled elements to the list --
subloops, portions of loops, dark fiber optic loops and transport -- but
declined, except in limited circumstances, to require ILEC's to unbundle the
facilities used to provide high-speed Internet access and other data services.
In addition, the FCC initiated a further rulemaking proceeding to consider
whether carriers should be able to combine certain unbundled elements to provide
special access services in competition with those provided by the ILECs.
Portions of the FCC's 1999 ruling have been appealed by several parties.

     In February 1999, the FCC determined that calls to ISPs are interstate in
nature, thus falling under the FCC's jurisdiction and outside the scope of the
Communications Act's reciprocal compensation requirements. The FCC initiated a
review of compensation arrangements for calls to ISPs but stated that, in the
meantime, parties may voluntarily include reciprocal compensation provisions in
their interconnection agreements and that state commissions may order
compensation for termination of ISP calls. Many states decided to leave intact
existing decisions in favor of reciprocal compensation for ISP-bound calls. On
March 24, 2000, the U.S. Court of Appeals for the D.C. Circuit overturned the
FCC's decision that calls to ISPs are not local. The court found that the FCC
had failed to explain adequately its determination that a call does not
"terminate" at an ISP merely because the ISP then originates further
telecommunications that extend beyond state boundaries. In response to this
court ruling, the FCC could try to bolster its original jurisdictional
conclusion or it could determine that calls to ISPs are local. If it takes the
latter course, CLECs will be entitled to reciprocal compensation under the
Communications Act for terminating ISP-bound traffic, which could have a
favorable impact on our revenues. Such a decision, however, could also
potentially lead to more state control over Internet-related services, which
could have a negative effect on our roll out of such services.


                                       23

<PAGE>   608
    Several ILECs have filed petitions at the FCC and have initiated legislative
efforts to effect a waiver of the obligation to unbundle and offer services for
resale with regard to high-speed data or "advanced" services. In addition, the
ILECs are seeking to provide such services on an interLATA (long distance) basis
before they have been granted approval by the FCC pursuant to Section 271 of the
Communications Act to enter the long distance market. Although the FCC has held
that advanced services continue to be subject to the resale and unbundling
obligations of the Act, it has commenced a proceeding to determine whether ILECs
can create separate affiliates for advanced services that would be free of these
obligations. In November 1999, the FCC ruled that DSL services that traditional
telephone companies sell to Internet service providers need not be resold to
competitive telecommunications providers at wholesale rates. In addition, an FCC
decision on voluntary remand from the U.S. Court of Appeals for the D.C. Circuit
affirmed and clarified the FCC's position that advanced services are subject to
the interconnection, resale, and unbundling requirements of the Act. Permitting
ILECs to provision data services through separate affiliates with fewer
regulatory requirements could have a material adverse impact on our ability to
compete in the data services sector. The FCC also imposed conditions on the
merger of SBC with Ameritech in October 1999 that permit the provisioning of
advanced data services via separate subsidiaries pursuant to various
requirements, some of which expire in the near term. We cannot predict whether
these requirements are enforceable, nor whether they will deter anticompetitive
behavior if they are enforceable. Bell Atlantic's application for long distance
service in New York has been approved subject to similar separate subsidiary
provisions. These areas of regulation are subject to change through additional
proceedings at the FCC or judicial challenge.

    On March 17, 2000, the U.S. Court of Appeals for the D.C. Circuit issued a
decision in which it vacated significant portions of an FCC order that granted
collocation rights to CLECs for advanced services equipment. In particular, the
court found that that FCC's order impermissibly appears to permit competitors to
collocate equipment that may do more than what is required to achieve
interconnection or access to unbundled network elements. It faulted the FCC for
requiring ILECs to permit collocation of any equipment that is "used or useful"
for either interconnection or access to unbundled elements "regardless of other
functionalities inherent in such equipment." It told the FCC to explain better
which types of equipment are actually "necessary" for interconnection or access.
On remand, the FCC could determine that much of the multi-function equipment
that CLECs generally wish to collocate today satisfies the court's "necessary"
standard. In fact, the court's only example of equipment that likely would not
meet the standard is equipment that facilitates payroll or data collection.
Nevertheless, it probably will be years before the FCC and the courts decide
this issue finally and, in the meantime, many ILECs may seek to interpret the
court's decision to mean that they do not have to permit the collocation of
multi-function equipment. This could significantly delay or hamper our network
deployment plans, which call for collocation of various types of equipment in
ILEC central offices.

    In this March 17, 2000 order, the court also overturned the FCC's
determination that ILECs must permit collocating CLECs to cross-connect their
facilities. The court stated that the FCC failed to explain how cross-connects
between CLECs are necessary for interconnection with or access to the unbundled
elements of the ILEC. In addition, the court rejected some of the FCC's
provisions regarding the implementation of physical collocation, such as the
requirement that ILECs give competitors the option of collocating equipment "in
any unused space." The immediate impact of these rulings is that ILECs may seek
to hinder physical collocation, driving up collocation costs. The FCC will have
the opportunity to offer explanations for its decisions, but such explanations
may not be issued in the near future. The March 17 order did uphold certain FCC
rules, including the requirement that ILECs provide cageless and adjacent
collocation, and rules regarding cost allocation.

    On December 9, 1999, the FCC released its line sharing order that requires
ILECs to offer line sharing as an unbundled network element by June 6, 2000.
Line sharing permits CLECs to use a customer's existing line to provide DSL
services while the ILEC continues to use the same line to provide voice service.
Prices for line sharing will be set by the states. The decision has been
appealed.

    There are also numerous bills being considered by Congress that would
deregulate the provision of advanced services by ILECs. These regulatory or
legislative outcomes could have an adverse effect on our ability to obtain
access to the network elements necessary for the provision of advanced services
to our customers or to compete with ILECs in the provision of such services.

LOCAL EXCHANGE CARRIER ENTRY INTO NEW MARKETS

    Our principal competitor in each market we enter is the ILEC. Prior to the
enactment of the Telecommunications Act, the RBOCs generally were prohibited by
the consent decree that broke up the Bell System from providing long distance
services. The Telecommunications Act established procedures under which a RBOC
can provide landline long distance services originating from (and in certain
cases, terminating in) its traditional telephone service area after receiving
approval from the FCC. The interconnection offered or provided by the RBOC must
comply with a competitive checklist that incorporates the interconnection
requirements discussed above. Please refer to the section entitled
"--Interconnection with Local Exchange Carrier Facilities." RBOCs are currently
permitted to provide landline long distance services to customers outside of
their local service areas and in conjunction with their mobile telephone service
offerings.

                                       24
<PAGE>   609




    Approval from the FCC will enable a RBOC to provide customers with a full
range of local and long distance telecommunications services. The provision of
landline long distance services by RBOCs is expected to reduce the market share
of the major long distance carriers, which may be significant customers of our
services. Consequently, the entry of the RBOCs into the long distance market may
have adverse consequences on the ability of CLECs both to generate access
revenues from the IXCs and to compete in offering a package of local and long
distance services. On December 22, 1999, the FCC approved an application filed
by Bell Atlantic seeking authority to begin providing long distance services to
customers located in the State of New York, where it also provides local
telephone service. This action represents the first approval by the FCC of an
RBOC request to provide long distance services to customers located in its local
operating region. The FCC's approval of Bell Atlantic's application is likely to
strengthen Bell Atlantic's competitive position in New York substantially. In
addition, we anticipate that Bell Atlantic will soon initiate similar
proceedings to obtain long distance service authority in other states in its
fourteen state operating region. For example, Bell Atlantic already has begun
the necessary regulatory review process in the Commonwealth of Massachusetts. In
addition, on January 10, 2000, Southwestern Bell filed an application with the
FCC seeking permission to provide long distance services to customers in Texas.
More RBOC requests to provide in-region long distance service are expected to be
filed with the FCC in the near future.

RELAXATION OF REGULATION

    A goal of the Telecommunications Act is to increase competition for
telecommunications services, thereby reducing the need for regulation of these
services. To this end, the Telecommunications Act requires the FCC to streamline
its regulation of ILECs and permits the FCC to forbear from regulating
particular classes of telecommunications services or providers. Since we are a
non-dominant carrier and, therefore, are not heavily regulated by the FCC, the
potential for regulatory forbearance likely will be more beneficial to the ILECs
than to us in the long run.

    The Communications Act requires all common carriers to charge just and
reasonable rates for their services and to file schedules of these rates with
the FCC. These schedules are known as "tariffs" and they represent a contract
between a carrier and its customers. The Telecommunications Act permits the FCC
to "forbear" from enforcing certain provisions of the Communications Act and the
FCC has used this authority to determine that it is in the public interest to
prohibit carriers from filing tariffs for their interstate services. This
decision of the FCC and its "mandatory detariffing" has been stayed by the U.S.
Court of Appeals for the D.C. Circuit. If the FCC is successful in its attempt
to preclude telecommunications providers from filing tariffs, it may increase
our exposure to litigation. Currently, tariffs contain provisions limiting the
liability of providers on a variety of issues. In the absence of filed tariffs,
carriers would have to rely on negotiated contracts with each customer to
provide such liability limitations.

    Another FCC decision permits, but does not require, CLECs to file tariffs
for the charges that they levy on interstate long distance carriers for
completing calls to CLEC customers (refer to the discussion of "access charges"
below). In the absence of a tariff, a carrier depends on a contract with its
customers to determine the rates and conditions of service.

UNIVERSAL SERVICE AND ACCESS CHARGE REFORM

    On May 8, 1997, the FCC issued an order implementing the provisions of the
Telecommunications Act relating to the preservation and advancement of universal
telephone service. This order requires all telecommunications carriers providing
interstate telecommunications services, including us, to contribute to universal
service support. Our share of the contributions used to support schools,
libraries and rural health care programs is based on our share of the total
industry end user telecommunications revenues. Our share of the federal
high-cost fund is based on our share of total interstate telecommunications
revenue. Although we have already begun contributing to the federal universal
service fund, the amount of our required contribution changes each quarter.
Various states are also in the process of implementing their own universal
service programs. We are currently unable to quantify the amount of subsidy
payments that we will be required to make and the effect that these required
payments will have on our financial condition.

    On July 30, 1999, the United States Court of Appeals for the Fifth Circuit
overturned certain of the FCC's rules governing the basis on which the FCC
collects subsidy payments from telecommunications carriers and recovery of those
payments by ILECs. In October 1999, the FCC released two orders in response to
the Fifth Circuit decision. One order permits ILECs to continue to recover their
universal service contributions from access charges or to establish end-user
charges. The second order changed the contribution basis for school/library
funding to eliminate calculations based upon intrastate revenues. A number of
parties have petitioned the Supreme Court to review the Fifth Circuit's
decision.


                                       25

<PAGE>   610




    In May 1999, the FCC adopted a framework for a new, forward-looking,
high-cost support mechanism that will provide support for non-rural
telecommunications carriers. The FCC stated that the support mechanism will be
used only to determine federal support and will not impose any obligation on a
state to impose intrastate surcharges. It is not possible to determine at this
time what effect this ruling will have on the level of contributions we are
required to make to either the federal or various state universal service
programs, or if it will become easier for us to become qualified as recipients
of universal service funds when we serve high-cost areas.

    In a related proceeding, on May 16, 1997, the FCC issued an order
implementing certain reforms to its access charge rules. Access charges are
charges imposed by local exchange carriers on long distance providers for access
to the local exchange network, and are designed to compensate the local exchange
carrier for its investment in the local network. The FCC regulates interstate
access and the states regulate intrastate access. This order required ILECs to
substantially decrease over time the prices they charge for switched and special
access and changed how access charges are calculated. These changes are intended
to reduce access charges paid by IXCs to local exchange carriers and shift
certain usage-based charges to flat-rated, monthly per-line charges. To the
extent that these rules are effective in reducing access charges, our ability to
offer customers lower-cost access services might be impaired. Additionally, the
FCC ruled that ILECs may no longer impose certain interconnection charges on
competitive providers that interconnect with the ILEC at the end offices but do
not use the transport facilities.

    On August 27, 1999, the FCC issued an order implementing further reforms to
its access charge rules. The FCC's order granted price cap LECs greater pricing
flexibility, and instituted other access charge reforms designed to increase
competition and reduce access charges. These changes could impair our ability to
offer customers lower-cost access services. The FCC also issued a notice of
proposed rulemaking, proposing additional pricing flexibility. In addition, the
FCC stated that it is considering whether to adopt rules constraining CLEC
access charges. To the extent CLEC access charges are reduced, our revenue could
decrease.

    Some state public service commissions have adopted rules or are currently
considering actions to preserve universal services and promote the public
interest.

FEDERAL REGULATION GENERALLY

    Through a series of proceedings, the FCC has established different levels of
regulation for "dominant carriers" and "non-dominant carriers." Only ILECs are
classified as dominant; all other providers of domestic interstate services are
classified as non-dominant carriers. As a non-dominant carrier, we are subject
to relatively limited regulation by the FCC. However, at a minimum, we must
offer interstate services at just and reasonable rates in a manner that is not
unreasonably discriminatory.

    The FCC has adopted rules requiring ILECs to provide collocation to CLECs
for the purpose of interconnecting their competing networks. Under the rules
adopted by the Local Competition Orders, ILECs are required to provide either
physical collocation or virtual collocation at their switching offices.
Recently, the FCC established new rules designed to make it easier and less
expensive for CLECs to obtain collocation at ILEC central offices by, among
other things, restricting the ILECs' ability to prevent certain types of
equipment from being collocated and requiring ILECs to offer alternative
collocation arrangements to CLECs. On March 17, 2000, however, the U.S. Court
of Appeals for the D.C. Circuit overturned several of these collocation rules,
finding that the FCC had failed to make a determination about whether all the
types of equipment ILECs are required to collocate is "necessary" for
interconnection or access to unbundled elements. According to the court, such a
determination is required under the Communications Act. The court also rejected
other FCC rules that permit CLECs to cross-connect their equipment with the
equipment of other CLECs and give CLECs the option of collocating equipment in
any unused space in an ILEC central office. While, ultimately, the FCC could
provide reasoned explanations for its current collocation requirements, the
uncertainty created by this court decision could provide ILECs with a basis for
refusing to collocate multi-function equipment or provide collocation in a
timely and efficient manner. This could have a negative impact on our network
deployment plans.

    All local exchange carriers, including CLECs, must:

    o    make their services available for resale by other carriers;

    o    provide nondiscriminatory access to rights-of-way;

    o    offer reciprocal compensation for termination of traffic; and

    o    provide dialing parity and telephone number portability.


                                       26

<PAGE>   611






    In addition, the Telecommunications Act requires all telecommunications
carriers to contribute to the universal service mechanism established by the FCC
and to ensure that their services are accessible to and usable by persons with
disabilities. Moreover, the FCC is considering the regulatory implications of
various aspects of local exchange competition. Any or all of these proceedings
may negatively affect CLECs, including us.

    The May 21, 1997 order reforming the FCC's price cap formula and the August
27, 1999 order granting ILECs substantial pricing flexibility with regard to
interstate access services afford ILECs greater flexibility in establishing
rates and provide additional incentives to foster efficiency. Because these
regulatory initiatives enable ILECs to offer selectively reduced rates for
access services, the rates we may charge for access services could be
constrained. Our rates also will be constrained by our competitors which,
excluding the ILECs, are subject to the same streamlined regulatory regime as us
and can price their services to meet competition.


STATE REGULATION GENERALLY

    Most state public service commissions require companies to be certified to
provide common carrier services. These certifications generally require a
showing that the carrier has adequate financial, managerial and technical
resources to offer the proposed services in a manner consistent with the public
interest.

    In addition to obtaining certification, in each state, we must negotiate
terms of interconnection with the incumbent local exchange carrier before we can
begin providing switched services. Under the Telecommunications Act, the FCC has
adopted interconnection requirements, certain portions of which have been upheld
by the United States Supreme Court and other portions of which are subject to
reconsideration by the FCC or further judicial review. Please refer to the
section entitled "--Interconnection with Local Exchange Carrier Facilities."
State public utility commissions are required to approve interconnection
agreements before they become effective and must arbitrate disputes among the
parties upon request. We have already entered into interconnection agreements
with Ameritech, Cincinnati Bell Telephone and Bell Atlantic. We have also
initiated the process of negotiations with Ameritech and Bell Atlantic for
additional interconnection agreements. Regulatory changes could require
renegotiation of relevant portions of existing interconnection agreements, or
subject them to additional court and regulatory proceedings.

    Some recent state regulatory commission decisions regarding the
applicability of the Telecommunications Act's reciprocal compensation provisions
to the termination of calls placed to ISPs could result in lower revenues for
CLECs in those states. The issue remains undecided in various other states.

    We are not presently subject to price regulation based on costs or earnings.
Most states require CLECs to file tariffs setting forth the terms, conditions
and prices for intrastate services. Some states permit tariffs to list a rate
range or set prices on an individual case basis.

    Several states provide ILECs with flexibility for their rates, special
contracts (selective discounting) and tariffs, particularly for services deemed
subject to competition. This pricing flexibility increases the ability of the
incumbent local exchange carrier to compete with us and constrains the rates we
may charge for its services. In light of the additional competition that is
expected to result from the Telecommunications Act, states may grant ILECs
additional pricing flexibility. At the same time, some ILECs may request
increases in certain local exchange rates to offset revenue losses due to
competition.

    The rates that may be charged by ILECs for access to loops and other network
elements are set by state public service commissions based on pricing
established by the FCC. Proposed changes to existing rates are currently being
considered by public service commissions in several states, including states in
which we are presently operating. If approved, these changes could increase our
costs of doing business, thus having an adverse effect on our operations.

REGULATION OF RESELLERS

    The FCC has defined resale as any activity in which a party (the reseller)
subscribes to the services or facilities of a facilities-based provider (or
another reseller) and then reoffers communications services to the public for
profit, with or without adding value. Resellers are common carriers generally
subject to all rules and regulations placed on providers of the underlying
services by either the FCC or the states in which they operate. The FCC has held
that prohibitions on the resale of common carrier services are unjust,
unreasonable, and unlawfully discriminatory in violation of the Communications
Act. Accordingly, all common carriers must make their services available for
resale at rates, terms, and conditions that do not unreasonably discriminate
against resellers. The Telecommunications Act imposes the additional duty upon
incumbent local exchange carriers to make their services available for resale at
wholesale rates. The FCC adopted specific requirements for determining such
wholesale rates for local telecommunications services. While the United States
Supreme Court upheld the FCC's authority to adopt these rules, the FCC's
specific pricing rules are subject to further judicial review. As to other
telecommunications services, however, there is no regulation that requires
discounts to resellers below those offered to end users of the same quantities
of like services. The FCC has determined that because of the competitive
development of broadband commercial mobile radio service, it will eliminate the
explicit requirement that those services be offered for resale after November
24, 2002.

LOCAL GOVERNMENT AUTHORIZATIONS

    Many jurisdictions where we may provide service require license or franchise
fees based on a percentage of certain revenues. Because the Telecommunications
Act specifically allows municipalities to charge fees for use of the public
rights-of-way, it is likely that jurisdictions that do not currently impose fees
will seek to impose fees in the future. However, the amount and basis of these
fees have been successfully challenged by several telecommunications service
providers. Federal courts have struck down municipal ordinances that (1) do not
relate the fees imposed under the ordinance to the extent of a provider's use of
the rights-of-way; (2) do not relate the fees imposed under the ordinance to the
costs incurred by the local government in maintaining the rights-of-way; or (3)
seek to impose fees based on a concept of the "value" of the use to the provider
by relating the fees to provider revenues. Additionally, because the
Telecommunications Act requires jurisdictions to charge non-discriminatory fees
to all telecommunications providers, telecommunications providers are
challenging municipal fee structures that excuse other companies, particularly
the ILECs, from paying license or franchise fees, or allow them to pay fees that
are materially lower than those that are required from new competitors such as
CoreComm. A number of these decisions have been appealed and, in any event, it
is uncertain how quickly particular jurisdictions will respond to the court
decisions without a specific legal challenge initiated by us or another CLEC to
the fee structure at issue.

LOCAL MULTIPOINT DISTRIBUTION SERVICE

    The FCC has established a new wireless service referred to as "Local
Multipoint Distribution Service" or LMDS. The FCC allocated two frequency blocks
in each of 493 Basic Trading Areas in the U.S. to LMDS: Block A with 1,150 MHz
of spectrum in the 28 GHz and 31 GHz bands, and Block B with 150 MHz in the 31
GHz band. LMDS licenses are awarded for ten-year terms with renewal expectancies
provided to licensees that make a showing of substantial service in their
licensed areas.

    LMDS may be used to provide any kind of communications service on a common
carrier or non common-carrier basis. Radio frequencies in the 28 and 31 GHz
bands are generally capable of only "line-of-sight" transmission and reception,
are subject to interference from certain weather conditions, and do not lend
themselves to mobile applications. LMDS is expected to be used for the delivery
of various broadband services to homes and offices, including
telecommunications, Internet access, and two-way video. At least seven other
countries, including Canada and Mexico, have licensed LMDS on either a permanent
or experimental basis. LMDS licensees are expected to be able to provide a wide
array of services, two-way capabilities, and high capacity through the use of
newer digital equipment and transmission mechanisms. The FCC expects that
Block-A LMDS licensees especially, by applying cellular-style frequency re-use
technology to an already large frequency bandwidth, have the potential to become
competitors to ILECs and cable operators. Accordingly, the LMDS rules prohibit
ownership of Block-A licenses by ILECs and incumbent cable operators prior to
July 2000, but permit an applicant that would otherwise be prohibited from
holding a Block-A license to apply for a waiver of the ownership restriction by
showing that it does not have market power in its telephone or cable service
area.

    The FCC held a simultaneous, multiple-round auction for the 986 LMDS
licenses which closed on March 25, 1998. 104 winning participants bid a total of
$578,663,029 for 864 licenses. No auction participant placed the minimum opening
bid on any of the remaining 122 licenses, which were reauctioned in April and
May, 1999. In the initial auction, we won 15 Block-A licenses for Basic Trading
Areas encompassing substantially all population centers in the state of Ohio,
for a total bid of $25,241,133. Auction participants that had average gross
revenues for the previous three years of $75 million or less, when aggregated
with all commonly controlled affiliates, were entitled to bidding credits of
25%, 35%, or 45%. We did not qualify for any bidding credit. The FCC has since
granted our 15 LMDS licenses with an effective date of June 8, 1998.

FUTURE INTERNATIONAL OPERATIONS

    We may ultimately expand our operations to other countries and already
provide international resale services. The FCC requires every carrier that
intends to originate international telecommunications from within the U.S.,
either through the use of its own facilities or on a resale basis, to secure in
advance an authorization from the FCC under Section 214 of the Communications
Act. Additionally, these carriers must file with the FCC a tariff containing the
rates, terms, and conditions of their international service offerings. In
applying for a 214 Authorization, a carrier must disclose any affiliations with
or special concessions from foreign carriers or nations. The FCC has streamlined
its procedures for granting 214 Authorizations, providing a routine grant of
such authorizations in 35 days unless an application is formally opposed or the
applicant is affiliated with a carrier that controls bottleneck
telecommunications facilities in a foreign country, in which case the applicant
may be subject to more stringent regulation as a "dominant" carrier.
Additionally, applicants affiliated with foreign carriers in countries that are
signatories to the Telecommunications Annex to the World Trade Organization
General Agreement of Trade in Services, including Canada, have a reduced burden
of demonstrating their "non-dominance." Carriers that have received 214
Authorizations are subject to certain reporting requirements, must file
contracts with foreign correspondents, and are restricted in the provision of
certain services to certain nations, such as the use of resold private lines for
switched services and the provision of any services to countries on the FCC's
"exclusion list." We hold a 214 Authorization for both facilities-based and
resale international services and have filed a tariff for our international
resale services.

INTERNET REGULATION

    The FCC currently does not regulate the provision of Internet service,
although it does regulate common carriers that provide elements of the
"backbone" networks on which the Internet is based. Similarly, state public
utility commissions generally do not regulate Internet service, except in some
limited circumstances where incumbent local exchange carriers provide Internet
services. The FCC and some states, however, are reviewing the development of the
Internet and the types of services that are provided through it. For example, if
the FCC should determine that an Internet service provider offers a service that
is an exact substitute for long distance telephone service with the sole
distinction that it is based on a packet-switched network rather than a
circuit-switched network, the FCC may determine that it should provide
regulatory parity for the services.

ITEM 2.  PROPERTY

    Certain of our subsidiaries lease switch buildings, ILEC collocations and
office space which we believe are adequate to serve our present business
operations and our needs for the foreseeable future. See the Notes to the
Consolidated Financial Statements included elsewhere in this Form 10-K for
information concerning lease commitments.

ITEM 3.  LEGAL PROCEEDINGS

    We are not involved in any legal disputes that we expect to have a material
adverse effect on our results of operations or financial condition.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF STOCKHOLDERS

    No matter was submitted to a vote of security holders of the Company during

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION.


                              RESULTS OF OPERATIONS


YEAR ENDED DECEMBER 31, 1999 AND FOR THE PERIOD FROM APRIL 1, 1998 (DATE
OPERATIONS COMMENCED) TO DECEMBER 31, 1998

     As a result of the completion of the acquisitions of 100% of the stock of
MegsINet Inc. and the CLEC assets of USN Communications, Inc. in May 1999, we
consolidated the results of operations of these businesses from the dates of
acquisition. The results of these businesses are not included in the 1998
results.

     A significant component of the 1999 results is associated with the
acquisition of certain assets of USN. Although USN quickly developed a large
customer list and revenue base in 1997 and 1998, it had difficulties under its
previous management providing services, including billing, customer care and
other operational areas, and filed for bankruptcy in February 1999. Since the
acquisition, we have been focusing on improving these operations, and have been
successful in many areas. However, we did not actively sell additional lines in
these markets in 1999 because we were not fully satisfied with the quality of
the operations. Consequently, and consistent with our due diligence, transaction
structure and purchase price, revenues associated with the USN assets have
declined significantly since our acquisition, and additional declines may
continue as customers leave or "churn" off the service.


                                       31

<PAGE>   616






     The increase in revenues to $58,151,000 from $6,713,000 is primarily due to
acquisitions in 1999, which accounted for $40,909,000 of the increase. The
remainder of the increase is primarily due to an increase in CLEC and ISP
revenues from an increase in customers, offset by the decline in cellular long
distance revenue as a result of customers switching to other long distance
providers. In the third quarter of 1999, we sold most of our prepaid cellular
debit card business and we terminated our cellular long distance business in
certain markets. We had revenues in 1999 of $2,223,000 from the prepaid cellular
debit card business and $519,000 from the cellular long distance business in
these markets.

     Operating costs increased to $58,561,000 from $5,584,000 primarily due to
acquisitions in 1999, which accounted for $43,315,000 of the increase. The
remainder of the increase is primarily due to the increase in revenues.
Operating costs as a percentage of revenues increased to 101% from 83%. The
increase in percentage terms is the result of an increase in the fixed component
of operating expenses due to the migration toward a facilities-based
infrastructure. Operating costs as a percentage of revenues is expected to
remain higher than 1998 levels until customer and revenue growth exceeds the
increases in facilities-based infrastructure costs. In 1999, operating costs
were $2,543,000 from the prepaid cellular debit card business and $458,000 from
the cellular long distance business in the terminated markets.

     Selling, general and administrative expenses increased to $74,185,000 from
$11,940,000 primarily due to acquisitions in 1999, which accounted for
$33,184,000 of the increase. The remainder of the increase is a result of
increased selling and marketing costs and increased customer service costs.
These costs are expected to increase in the foreseeable future as we grow our
operations and customer base.

     Corporate expenses include the costs of our officers and headquarters
staff, the costs of operating the headquarters and costs incurred for strategic
planning and evaluation of business opportunities. Corporate expenses increased
to $7,996,000 from $2,049,000 because the 1998 expenses did not represent a full
period of results due to the fact that the spin-off from CCPR occurred on
September 2, 1998, at which time corporate expenses commenced. In addition,
allocated charges from NTL Incorporated (a company that has some of the same
officers and directors as CoreComm) have increased due to the sales in 1999 of
other affiliated companies.

     The non-cash compensation charge of $1,056,000 in 1999 is recorded in
accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees,"
related to a change in employee stock option agreements. The non-cash
compensation charge of $4,586,000 in 1998 is recorded in accordance with APB
Opinion No. 25, as a one time charge related to the issuance of the Company's
warrants and stock options to holders of CCPR's stock options in connection with
the Company's distribution to CCPR's shareholders.

     Depreciation expense increased to $10,945,000 from $749,000 as a result of
acquisitions in 1999, which accounted for $7,176,000 of the increase and an
increase in fixed assets.

     Amortization expense increased to $8,633,000 from $231,000 due to the
amortization of goodwill and other intangibles from the acquisitions in 1999.

     Interest income and other, net, increased to $5,773,000 from $2,632,000
primarily due to interest income on the Company's cash, cash equivalents and
marketable securities.

     Interest expense increased to $5,341,000 from $21,000 primarily due to
interest on the 6% Convertible Subordinated Notes issued in October 1999 and
interest on notes payable and capital leases of acquired businesses.

FOR THE PERIOD FROM APRIL 1, 1998 (DATE OPERATIONS COMMENCED) TO DECEMBER 31,
1998 AND FOR THE YEAR ENDED DECEMBER 31, 1997

     As a result of the completion of the acquisitions of Digicom, Inc. in April
1998, certain assets of JeffRand Corp. (known as Wireless Outlet) in April 1998,
certain assets of OCOM Corporation in June 1998, and certain assets of Stratos
Internet Group, Inc. in November 1998, we consolidated the results of operations
of these businesses from the dates of acquisition. The following discussion
includes a comparison to the results of operations of OCOM, our predecessor
business. OCOM's primary historical business was its cellular long distance
resale business that has been and currently is a highly competitive segment of
the long distance telephone market.

     The increase in revenues to $6,713,000 from $3,579,000 is primarily due to
acquisitions in 1998, which accounted for $4,535,000 of the increase. OCOM's
revenues decreased to $2,178,000 from $3,579,000 because OCOM's revenues prior
to its acquisition in June 1998 of $1,452,000 are not included in the 1998
amount. OCOM's cellular long distance revenues continued to decline in 1998 as a
result of customers switching to other long distance providers. This reduction
in revenues was offset by increases in CLEC and cellular revenues.

     Operating costs increased to $5,584,000 from $1,581,000 primarily due to
acquisitions in 1998, which accounted for $3,895,000 of the increase. Operating
costs as a percentage of revenues increased to 83% from 44%. This increase is
the result of the reduction in cellular long distance revenues which to date has
the highest gross margin of our telecommunications businesses.

     Selling, general and administrative expenses increased to $11,940,000 from
$5,934,000 as a result of increased selling and marketing costs and increased
customer service costs. These increases were offset by a reduction in billing
costs due to the implementation of in-house billing in the fourth quarter of
1997.

     The non-cash compensation charge of $4,586,000 in 1998 is a one time charge
related to the issuance of the Company's warrants and stock options to holders
of CCPR's stock options in connection with the Company's distribution to CCPR's
shareholders.

     Depreciation expense increased to $749,000 from $428,000 as a result of an
increase in fixed assets, primarily computer hardware and software.

     Amortization expense increased to $231,000 from $11,000 due to the
amortization of goodwill from the acquisitions in 1998.

     Interest income and other, net, increased to income of $2,632,000 from
expense of $4,000 primarily due to $2,585,000 of interest income on the
Company's cash, cash equivalents and marketable securities.

     Interest expense increased to $21,000 from zero due to interest on the note
payable and capital leases.

     March 2000 non-cash compensation expense. In March 2000, the Compensation
and Option Committee of the Board of Directors approved the issuance of options
in the Company to various employees to acquire approximately 2.7 million shares
of the Company's common stock at an exercise price of 30% of the fair market
value of our common stock on the date of the grant. In accordance with APB
Opinion No.25, "Accounting for Stock Issued to Employees," we will record a
non-cash compensation expense of approximately $44.8 million in March 2000 and a
non-cash deferred expense of approximately $48.5 million. We will charge the
deferred expense to non-cash compensation expense on a straight-line basis over
the vesting period of the stock options as follows: $15 million in 2000, $20
million in 2001, $11.6 million in 2002, $1.8 million in 2003 and $0.1 million
in 2004.

                         LIQUIDITY AND CAPITAL RESOURCES

     We will require significant resources to fund the construction of our
facilities-based network, develop and expand our existing businesses and fund
near term operating losses and debt service. We estimate that these requirements
will aggregate approximately $275 million in 2000, which excludes the effect of
the proposed acquisitions of ATX and Voyager.net. We intend to use cash and
securities on hand of $178.7 million at December 31, 1999 to meet a portion of
our operating and capital requirements. We are currently negotiating with
equipment manufacturers to provide us with additional vendor financing, and we
currently anticipate obtaining additional financing in the future. However,
there can be no assurance that the proposed financings will occur.

     Acquisitions. In May 1999, we acquired MegsINet and the CLEC assets of USN
Communications. The USN acquisition includes a contingent payment in July 2000
which is payable only if the USN assets meet or exceed operating performance
thresholds. The total additional cash consideration that we may pay for the USN
assets is capped at $58.6 million. We do not expect the actual contingent
payment to be significant.

     In the future, we plan to make further appropriate acquisitions which may
require significant acquisition related and capital expenditures. On March 10,
2000, we announced that the Company had entered into a definitive agreement to
acquire ATX Telecommunications Services, Inc. and on March 13, 2000, the Company
and Voyager.net, Inc. announced a definitive agreement to merge in a stock and
cash transaction. We will require between $80 million and $150 million in cash
for the ATX acquisition and approximately $95 million in cash for the
Voyager.net merger. In addition, we will issue new shares of convertible
preferred stock and common stock to the shareholders of ATX, and new shares of
common stock to the shareholders of Voyager.net. We are evaluating our financing
options and anticipate issuing additional debt and/or equity to fund the cash
portion of these acquisitions.

     Historical Uses of Cash. For the year ended December 31, 1999, cash used in
operating activities increased to $72,417,000 from $12,322,000 in the period
from April 1, 1998 (date operations commenced) to December 31, 1998, primarily
due to the increase in the net loss to $103,524,000 from $16,255,000. The net
loss increased as a result of acquisitions and an increase in selling and
marketing costs and customer service expenses as we have grown the business.

     For the year ended December 31, 1999, cash used to purchase fixed assets
increased to $20,575,000 from $2,341,000 in the period from April 1, 1998 (date
operations commenced) to December 31, 1998. The increase was due to acquisitions
and as a result of an increase in fixed asset purchases. The cash used for
acquisitions of $47,056,000 in the year ended December 31, 1999 is primarily for
payments in connection with the MegsINet and USN acquisitions.

     Proceeds from borrowings, net of financing costs, of $168,545,000 in 1999
is primarily from the issuance of the 6% Convertible Subordinated Notes.

     Network Construction. We intend to significantly expand our
telecommunications infrastructure in the United States over the next several
years. We have installed switches and other facilities, and we are in the
process of installing additional switches, Internet points-of-presence, and
other telecommunications facilities in many states. The amount of such
expenditures in 2000 will be related to the number of new markets entered, the
speed and location of equipment deployment, the timing and integration of
acquisitions, as well as the mix of resold vs. facilities-based services.

     We have deployed our Smart LEC facilities in Columbus, Ohio, Cleveland,
Ohio and Chicago, Illinois and are currently developing three additional
markets: Detroit, Michigan, New York, New York and Boston, Massachusetts. These
six markets comprise approximately 18 million total access lines. In connection
with these markets, we are in the process of establishing collocation facilities
in approximately 133 ILEC central offices. We have also identified approximately
30 additional markets where we intend to deploy our Smart LEC network in
2000-2002.


                                       34

<PAGE>   619




     We believe that our Smart LEC strategy enables us to enter and construct
our networks into new cities with relatively low up-front expenditures and a
significant proportion of success-based capital expenditures. Depending on the
size of the market, we expect our up-front capital expenditures to be
approximately $7 to $10 million, which includes the costs of installing our
switch facility and our collocation facilities and other related initial set-up
and installation expenses.

     The significant majority of the additional capital costs will be based on
subscriber levels. These costs will include equipment to increase network
capacity, such as ports and modems in our switch and access devices. These costs
will vary based on the type, volume and services of each customer, but are
estimated to be approximately $400-$500 per line. For example, a sample target
market may have 1 million business lines and 2 million residential lines, for a
total of 3 million lines. Our total level of capital expenditures for that
market will depend on our level of penetration. If we are able to gain 3%
overall penetration of the market, we would serve approximately 90,000 lines,
and based on approximately $400-$500 per line, we would spend approximately
$35-$45 million on additional capital costs developing and expanding our
networks in the market. A lower or higher penetration would decrease or
increase, respectively, our additional capital costs.

     The foregoing summary of the cost structure of our entry into a typical
market does not purport to be indicative of our performance, but is provided
solely as a basis for understanding our basic cost structure for individual
communications services in a typical target market. You should be aware that our
actual performance could differ materially from our current expectations.

     Operations. Our businesses will also consume capital to acquire new
customers and to finance the working capital required to support these new
customers. These businesses will also require additional billing, customer
service and other back-office infrastructure. These capabilities can be expanded
in-house or can be outsourced to reduce up-front capital requirements. To date,
our strategy has been to utilize the expertise developed by our management to
develop in-house billing and back-office capabilities.

     LMDS. LMDS is a fixed broadband wireless service that may be used to
provide high-speed data transfer, telephone service, telecommunications network
transmission, Internet access, video broadcasting, video conferencing, and other
services. The spectrum is useable for communications services from a fixed
antenna, but is not suitable for mobile or portable communications. LMDS can be
used to provide a wireless high-capacity broadband service for the "last mile"
to a home or office.

     The amount of capital required to construct our LMDS systems is not easily
quantifiable at this time, but is likely to be several times the $25 million
cost of the licenses. In addition to up-front network construction costs, a
significant ongoing capital requirement will be the cost to acquire customer
premise equipment to receive and transmit LMDS signals. We will deploy this LMDS
network only if we determine that we can achieve sufficient returns on our
capital invested, from reduced costs associated with providing our services or
from new services which we can offer through LMDS technology.

     Sources of Liquidity. Our operations were initially funded by the $150
million cash capital contribution from CCPR in connection with the spin-off. In
October 1999, we issued $175 million principal amount of 6% Convertible
Subordinated Notes due 2006, and received net proceeds of $168.5 million.
Interest on the Convertible Subordinated Notes is payable semiannually on April
1 and October 1 of each year, commencing April 1, 2000. We expect to experience
substantial negative cash flow for the next several years due to the continued
development of our Smart LEC network and our other businesses. Our cash flow
requirements will depend upon:

     o   our network development schedules;

     o   acquisition opportunities;

     o   operating results; and

     o   technological developments.


                                       35

<PAGE>   620




     We are currently negotiating with equipment manufacturers, including Cisco
Systems, Inc., Lucent Technologies, Inc. and others to provide us with
additional vendor financing. In the aggregate, such financings are anticipated
to be significant. We are presently in the process of negotiating terms for
these transactions. However, until definitive agreements are reached with each
vendor, we cannot be certain that the proposed financings will occur, that the
terms will not change or that any alternative financing on terms satisfactory to
us will be available.

     Our ability to raise additional capital will be dependent on a number of
factors, such as general economic and market conditions, which are beyond our
control. If we are unable to obtain additional financing or to obtain it on
favorable terms, we may be required to delay the construction of our Smart LEC
network, forego attractive business opportunities, or take other actions which
could adversely affect our business, results of operations and financial
condition.

     We are a holding company with no significant assets other than cash and
securities and investments in and advances to our subsidiaries. We are therefore
likely to be dependent upon receipt of funds from our subsidiaries to meet our
own obligations. However, our subsidiaries' proposed debt agreements may prevent
the payment of dividends, loans or other distributions to us (except in certain
limited circumstances).

YEAR 2000

     We had a comprehensive Year 2000 project designed to identify and assess
the risks associated with our information systems, products, operations,
infrastructure, suppliers and customers, and to develop, implement and test
remediation and contingency plans to mitigate these risks. To date, we have not
experienced any significant problems related to the Year 2000.

     Because we use a variety of information systems and have additional systems
embedded in our operations and infrastructure, we cannot be sure that all of our
systems will continue to work together in a Year 2000-ready fashion.
Furthermore, we cannot be sure that we will not suffer business interruptions,
either because of our own Year 2000 problems or those of third-parties upon whom
we are reliant for services. Therefore, a problem that has not yet been
identified may arise and could have adverse consequences to us.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK.

     The Securities and Exchange Commission's rule related to market risk
disclosure requires that we describe and quantify our potential losses from
market risk sensitive instruments attributable to reasonably possible market
changes. Market risk sensitive instruments include all financial or commodity
instruments and other financial instruments (such as investments and debt) that
are sensitive to future changes in interest rates, currency exchange rates,
commodity prices or other market factors. We are not exposed to market risks
from changes in foreign currency exchange rates or commodity prices. We do not
hold derivative financial instruments nor do we hold securities for trading or
speculative purposes. Under our current policies, we do not use interest rate
derivative instruments to manage our exposure to interest rate changes.

     The fair-market value of long-term fixed interest rate debt is subject to
interest rate risk. Generally the fair market value of fixed interest rate debt
will increase as interest rates fall and decrease as interest rates rise. The
fair value of our Convertible Subordinated Notes was determined from the quoted
market price. The fair value of our other notes payable are estimated using
discounted cash flow analyses, based on our current incremental borrowing rates
for similar types of borrowing arrangements.

                         Report of Independent Auditors



Shareholders and Board of Directors
CoreComm Limited

We have audited the consolidated balance sheet of CoreComm Limited and
Subsidiaries as of December 31, 1999 and 1998, and the related consolidated
statements of operations, shareholders' equity and cash flows for the year ended
December 31, 1999 and for the period from April 1, 1998 (date operations
commenced) to December 31, 1998. Our audits also included the financial
statement schedule listed in the Index at Item 14(a) for the year ended December
31, 1999 and for the period from April 1, 1998 (date operations commenced) to
December 31, 1998. These financial statements and schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
CoreComm Limited and Subsidiaries at December 31, 1999 and 1998, and the
consolidated results of their operations and their cash flows for the year ended
December 31, 1999 and for the period from April 1, 1998 (date operations
commenced) to December 31, 1998 in conformity with accounting principles
generally accepted in the United States. Also, in our opinion, the related
financial statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

             and its Predecessor OCOM Corporation Telecoms Division

                   Notes to Consolidated Financial Statements

1.   ORGANIZATION AND BUSINESS

     CoreComm Limited (the "Company"), formerly a wholly-owned subsidiary of
     Cellular Communications of Puerto Rico, Inc. ("CCPR"), was formed in March
     1998 (operations commenced in April 1998) in order to succeed to the
     businesses and assets that were operated by OCOM Corporation and as an
     appropriate vehicle to pursue new telecommunications opportunities outside
     of Puerto Rico and the U.S. Virgin Islands. In September 1998, CCPR made a
     cash contribution to the Company of $150,000,000 and distributed 100% of
     the outstanding shares of the Company on a one-for-one basis to CCPR's
     shareholders.

     The Company's competitive local exchange carrier ("CLEC"), cellular long
     distance, landline long distance and cellular resale businesses were
     formerly owned and operated by OCOM Corporation Telecoms Division ("OCOM").
     CCPR acquired the operating assets and related liabilities of these
     businesses from OCOM on June 1, 1998. OCOM is the predecessor business to
     the Company.

     The Company seeks to become a leading provider of integrated telephone,
     Internet and data services to business and residential customers in
     targeted markets throughout the United States. As of December 31, 1999, the
     Company's customers are located throughout the United States, although much
     of the Company's business is conducted in Ohio and Illinois.

     The Company's performance will be affected by, among other things, its
     ability to implement expanded interconnection and collocation with the
     facilities of incumbent local exchange carriers ("ILECs") and develop
     efficient and effective working relationships with the ILECs and other
     carriers. The Company has installed, and is currently in the process of
     installing, its own switches and related equipment in certain of its
     markets. The Company will continue to lease the unbundled local loop needed
     to connect its customers to its switches. The Company purchases capacity
     from the ILECs on a wholesale basis pursuant to contracts and sells it at
     retail rates to its customers. The Company depends upon the ILECs to
     maintain the quality of their service to the Company's customers. Also,
     except for CLEC customers who are connected to one of the Company's
     switches and Internet services customers, the Company depends upon the
     ILECs for accurate and prompt billing information in order for the Company
     to bill its customers.

     The Company's business is highly competitive which results in pricing
     pressure and increasing customer acquisition costs. Expenses are expected
     to exceed revenues in each location in which the Company offers service
     until a sufficient customer base is established. It is anticipated that
     obtaining a sufficient customer base will take a number of years, and
     positive cash flows from operations are not expected in the near future.

2.   SIGNIFICANT ACCOUNTING POLICIES

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the amounts reported in the financial statements
     and accompanying notes. Actual results could differ from those estimates.

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company,
     its wholly-owned subsidiaries and those entities where the Company's
     interest is greater than 50%. Significant intercompany accounts and
     transactions have been eliminated in consolidation.

     CASH EQUIVALENTS

     Cash equivalents are short-term highly liquid investments purchased with a
     maturity of three months or less. Cash equivalents were $71,564,000 and
     $20,995,000 at December 31, 1999 and December 31, 1998, respectively, and
     consisted of corporate commercial paper.

             Notes to Consolidated Financial Statements (continued)

2.   SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     MARKETABLE SECURITIES

     Marketable securities are classified as available-for-sale, which are
     carried at fair value. Unrealized holding gains and losses on securities,
     net of tax, are carried as a separate component of shareholders' equity.
     The amortized cost of debt securities is adjusted for amortization of
     premiums and accretion of discounts to maturity. Such amortization is
     included in interest income. Realized gains and losses and declines in
     value judged to be other than temporary will be included in interest
     income. The cost of securities sold or matured is based on the specific
     identification method. Interest on securities is included in interest
     income.

     Marketable securities at December 31, 1999 consisted of corporate
     commercial paper. Marketable securities at December 31, 1998 consisted of a
     certificate of deposit and corporate commercial paper. During the year
     ended December 31, 1999 and the period from April 1, 1998 (date operations
     commenced) to December 31, 1998, there were no realized gains or losses on
     sales of securities. All of the marketable securities as of December 31,
     1999 and 1998 had a contractual maturity of less than one year.

     ALLOWANCE FOR DOUBTFUL ACCOUNTS

     The Company records an estimate of uncollectible accounts receivable based
     on the current aging of its receivables and its prior collection
     experience.

     FIXED ASSETS

     Fixed assets are stated at cost. Depreciation is computed by the
     straight-line method over the estimated useful lives of the assets.
     Estimated useful lives are as follows: operating equipment - 3 to 15 years,
     computer hardware and software - 3 or 5 years and other equipment - 2 to 7
     years, except for leasehold improvements for which the estimated useful
     lives are the term of the lease.

     Long-lived assets are reviewed for impairment whenever events or changes in
     circumstances indicate that the carrying amount may not be recoverable. If
     the sum of the expected future undiscounted cash flows is less than the
     carrying amount of the asset, a loss is recognized for the difference
     between the fair value and carrying value of the asset.

     GOODWILL

     Goodwill is the excess of the purchase price over the fair value of net
     assets acquired in business combinations accounted for as purchases.
     Goodwill is amortized on a straight-line basis over the period benefited,
     which is estimated to be 5 to 10 years. The Company continually reviews the
     recoverability of the carrying value of goodwill using the same methodology
     that it uses for the evaluation of its other long-lived assets.

     LMDS LICENSE COSTS

     The costs incurred to acquire the Local Multipoint Distribution Service
     ("LMDS") licenses from the Federal Communications Commission (the "FCC")
     were deferred and will be amortized on a straight-line basis over the term
     of the licenses upon the commencement of operations. The Company
     continually reviews the recoverability of the carrying value of LMDS
     licenses using the same methodology that it uses for the evaluation of its
     other long-lived assets.

     OTHER ASSETS

     Other assets include customer lists, deferred financing costs and
     noncompetition agreements. Customer lists represent a portion of the excess
     of the purchase price over the fair value of net assets acquired in
     business combinations accounted for as purchases and are amortized on a
     straight-line basis over 2 to 7 years. Deferred financing costs were
     incurred in connection with the issuance of debt and are charged to
     interest expense over the term of the related debt. Noncompetition
     agreements obtained in connection with an acquisition were valued at
     $100,000 and are being charged to expense on a straight-line basis over the
     noncompetition period of 5 years. The Company continually reviews the
     recoverability of the carrying value of these assets using the same
     methodology that it uses for the evaluation of its other long-lived assets.

     NET (LOSS) PER SHARE

     The Company reports its net (loss) per share in accordance with Financial
     Accounting Standards Board ("FASB") Statement of Financial Accounting
     Standards ("SFAS") No. 128, "Earnings Per Share". The weighted average
     shares used for the computation of net (loss) per share prior to September
     1998 are equivalent to CCPR's historical weighted average shares (since
     CCPR shareholders received one share of the Company for each CCPR share
     owned). The shares issuable upon the exercise of stock options, warrants
     and convertible securities are excluded from the calculation of net (loss)
     per share as their effect would be antidilutive.

2.   SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     NET (LOSS) PER SHARE (CONTINUED)

     In 1999 and 1998, the Company had 18.0 million and 9.8 million shares,
     respectively, issuable upon the exercise of stock options, warrants and
     convertible securities that have been excluded from the calculation of net
     (loss) per share as their effect would be antidilutive. In 1997, CCPR had
     5.3 million shares issuable upon the exercise of stock options that have
     been excluded from the calculation of net loss per share as their effect
     would be antidilutive.

     REVENUE RECOGNITION

     Revenue is recognized at the time service is provided to the customer.
     Charges for services that are billed in advance are deferred and recognized
     when earned.

     ADVERTISING EXPENSE

     The Company charges the cost of advertising to expense as incurred.
     Advertising expense for the year ended December 31, 1999, for the period
     from April 1, 1998 (date operations commenced) to December 31, 1998, for
     the period from January 1, 1998 to May 31, 1998 and for the year ended
     December 31, 1997 was $4,407,000, $812,000, $79,000 and $127,000,
     respectively.

     STOCK-BASED COMPENSATION

     The Company has adopted the disclosure-only provisions of SFAS No. 123,
     "Accounting for Stock-Based Compensation." The Company applies APB Opinion
     No. 25, "Accounting for Stock Issued to Employees" and related
     interpretations in accounting for its stock option plans.

     RECLASSIFICATIONS

     Certain prior year amounts have been reclassified to conform to the 1999
     presentation.

3.   RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
     Instruments and Hedging Activities," which is required to be adopted by the
     Company effective January 1, 2001. Management does not anticipate that the
     adoption of this new standard will have a significant effect on the results
     of operations, financial condition or cash flows of the Company.

     In 1998, the Company adopted SFAS No. 130, "Reporting Comprehensive Income"
     and SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
     Information", both of which had no effect on the consolidated financial
     statements. The Company operates in a single business segment.

4.   ACQUISITIONS

     In May 1999, the Company acquired 100% of the stock of MegsINet Inc., a
     national Internet Service Provider ("ISP") with a national Asynchronous
     Transfer Mode network and local telecommunications facilities in Chicago
     for a total consideration of $16.8 million in cash and 3.2 million shares
     of the Company's common stock. In addition, the Company exchanged MegsINet
     stock options for options to purchase 444,000 shares of the Company's
     common stock, repaid $2.0 million of MegsINet debt and incurred acquisition
     related costs of $1.2 million. The common stock portion of the
     consideration was valued at $30.8 million, the fair value on the date prior
     to the announcement. The stock options were valued at $4.0 million using
     the Black-Scholes option pricing model.

     Also in May 1999, the Company acquired the wireline assets of USN
     Communications, Inc., which was a CLEC that operated on a resale basis, for
     a cash payment of $26.4 million, warrants to purchase 563,000 shares of the
     Company's common stock at a price of $13.33 per share and 225,000 shares at
     a price of $22.22 per share, and a potential contingent cash payment to be
     paid in July 2000 which is capped at $58.6 million. The contingent payment
     is payable only if the USN assets meet or exceed operating performance
     thresholds. The Company does not expect the actual payment in July 2000 to
     be significant. The warrants were valued at $9.1 million, the fair value on
     the date of issuance. In addition, the Company incurred acquisition related
     costs of $1.0 million.

     These acquisitions have been accounted for as purchases, and, accordingly,
     the net assets and results of operations of the acquired businesses have
     been included in the consolidated financial statements from the dates of
     acquisition. The aggregate purchase price of $91.3 million exceeded the
     fair value of the net tangible assets acquired by $75.6 million, which was
     allocated as follows: $13.3 million to customer lists, $1.5 million to
     other intangibles and $60.8 million to goodwill.

     In April and June 1998, CCPR acquired the stock of Digicom, Inc. and
     certain operating assets and related liabilities of Jeff Rand Corp. (known
     as the Wireless Outlet) and OCOM Corporation. CCPR contributed these
     businesses to the Company. These acquisitions were accounted for as
     purchases by CCPR, and, accordingly, the net assets and results of
     operations of the acquired businesses have been included in the
     consolidated financial statements from the dates of acquisition. The
     contribution of the assets from CCPR to the Company was accounted for at
     historical cost in a manner consistent with a transfer of entities under
     common control which is similar to that used in a "pooling of interests".
     The Company's financial statements include the results of the contributed
     companies for all periods owned by CCPR. In November 1998, a wholly-owned
     subsidiary of the Company acquired substantially all of the assets and
     certain liabilities of Stratos Internet Group, Inc. ("Stratos"), an ISP in
     the Cleveland-Akron, Ohio area. This acquisition has been accounted for as
     a purchase, and, accordingly, the net assets and results of operations of
     Stratos have been included in the consolidated financial statements from
     the date of acquisition. The aggregate purchase price of $5.2 million
     exceeded the fair value of net tangible assets acquired by $4.4 million,
     which was allocated as follows: $100,000 to noncompetition agreements and
     $4.3 million to goodwill.

4.   ACQUISITIONS (CONTINUED)

     The pro forma unaudited consolidated results of operations for the years
     ended December 31, 1999 and 1998 assuming consummation of the acquisitions
     and receipt of the capital contributions from CCPR as of January 1, 1998
     are as follows. The pro forma net (loss) and basic and diluted net (loss)
     per share do not give effect to interest income that may have been earned
     had the $150,000,000 cash capital contribution from CCPR been made on
     January 1, 1998.

</TABLE>

     A significant component of the pro forma results is associated with the
     acquisition of certain assets of USN. Although USN quickly developed a
     large customer list and revenue base in 1997 and 1998, it had difficulties
     under its previous management providing services, including billing,
     customer care and other operational areas, and filed for bankruptcy in
     February 1999. Since the acquisition, we have been focusing on improving
     these operations, and have been successful in many areas. However, we did
     not actively sell additional lines in these markets in 1999 because we were
     not fully satisfied with the quality of the operations. Consequently, and
     consistent with our due diligence, transaction structure and purchase
     price, revenues associated with the USN assets have declined significantly
     since our acquisition, and additional declines may continue as customers
     leave or "churn" off the service.

5.   LMDS LICENSE COSTS

     Cortelyou Communications Corp. ("Cortelyou"), a wholly-owned subsidiary of
     the Company, was the successful bidder for 15 Block A LMDS licenses in
     Ohio. The LMDS licenses were acquired for an aggregate of $25,366,000,
     which includes costs incurred of $125,000. LMDS frequencies are expected to
     be used for the provision of voice, data, video and Internet services to
     businesses and homes in competition with ILECs and/or cable television
     operators. The FCC has allocated two blocks of frequencies to be licensed
     in each of the 493 Basic Trading Areas in the United States and its
     territories based on an auction that ended in March 1998.

     In October 1999, the Company issued $175,000,000 principal amount of 6%
     Convertible Subordinated Notes due 2006 (the "Convertible Notes"). Interest
     on the Convertible Notes is payable semiannually on April 1 and October 1
     of each year, commencing April 1, 2000. The Convertible Notes are unsecured
     obligations convertible into common stock prior to maturity at a conversion
     price of $27.39 per share, subject to adjustment. There are approximately
     6.4 million shares of common stock reserved for issuance upon conversion of
     the Convertible Notes. The Convertible Notes are redeemable, in whole or in
     part, at the option of the Company, at any time on or after October 1,
     2002, at a redemption price of 103.429% that declines annually to 100% in
     2006, in each case together with accrued and unpaid interest to the
     redemption date. The Company incurred $6,935,000 in fees and expenses in
     connection with the issuance of the Convertible Notes, which is included in
     deferred financing costs.

     MegsINet originally borrowed $4,000,000 from Ascend Communications, Inc.
     ("Ascend") under a working capital promissory note dated August 1998.
     MegsINet is required to make monthly principal and interest payments of
     $148,000 through January 2002. The Company issued a warrant to Ascend to
     purchase approximately 29,000 shares of the Company's common stock at
     $13.75 per share in connection with the promissory note.

     In 1998, MegsINet entered into an agreement with Cisco Systems Capital
     Corporation ("Cisco"), whereby MegsINet can purchase operating equipment
     under a promissory note. Monthly payments of principal and interest
     commenced in 1999, MegsINet paid an aggregate of $3,164,000. MegsINet is
     required to make monthly principal and interest payments that decline each
     month from $366,000 beginning in January 2000 through September 2001. The
     Company has guaranteed the obligations of MegsINet under the promissory
     note.

     The Company issued a note payable in the amount of $362,000 in connection
     with the Stratos acquisition. Interest on the note accrues at 5.542% per
     annum. The note is payable in twelve consecutive quarterly payments of
     principal and interest of $33,000 which commenced in May 1999 and is

9.   FAIR VALUES OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used by the Company in
     estimating its fair value disclosures for financial instruments:

     Cash and cash equivalents: The carrying amounts reported in the
     consolidated balance sheets approximate fair value.

     Notes payable: The fair value of the Company's convertible notes is based
     on the quoted market price. The fair value of the Company's other notes
     payable are estimated using discounted cash flow analyses, based on the
     Company's current incremental borrowing rates for similar types of
     borrowing arrangements.

     The carrying amounts and fair values of the Company's financial instruments
     are as follows:

12.  RELATED PARTY TRANSACTIONS

     Some of the officers and directors of the Company are also officers or
     directors of NTL Incorporated ("NTL"). NTL provides the Company with
     management, financial, legal and technical services, access to office space
     and equipment and use of supplies. Amounts charged to the Company by NTL
     consist of salaries and direct costs allocated to the Company where
     identifiable, and a percentage of the portion of NTL's corporate overhead
     which cannot be specifically allocated to NTL (which is agreed upon by the
     Board of Directors of NTL and the Company). NTL's charges to the Company
     commenced in October 1998. It is not practicable to determine the amounts
     of these expenses that would have been incurred had the Company operated as
     an unaffiliated entity. In the opinion of management, this allocation
     method is reasonable. In 1999 and 1998, NTL charged the Company $2,330,000
     and $313,000, respectively, which is included in corporate expenses.

     The Company provides NTL with access to office space and equipment and the
     use of supplies. In the fourth quarter of 1999, the Company began charging
     NTL a percentage of the Company's office rent and supplies expense. It is
     not practicable to determine the amounts of these expenses that would have
     been incurred had the Company operated as an unaffiliated entity. In the
     opinion of management, this allocation method is reasonable. In 1999, the
     Company charged NTL $62,000, which reduced corporate expenses.

     A subsidiary of the Company provides billing and software development
     services to subsidiaries of NTL. The Company charges an amount in excess of
     its costs to provide these services. General and administrative expenses
     were reduced by $800,000, $275,000, $138,000, and $217,000 for the year
     ended December 31, 1999, the period from April 1, 1998 (date operations
     commenced) to December 31, 1998, the period from January 1, 1998 to May 31,
     1998 and the year ended December 31, 1997, respectively, as a result of
     these charges.

     At December 31, 1999, due from affiliates was comprised of $195,000 due
     from NTL. At December 31, 1998, due from affiliates included $128,000 due
     from CCPR and $1,826,000 due from NTL.

13.  401(k) PLAN

     The Company sponsors a 401(k) Plan in which all full-time employees who
     have completed 90 days of employment and are 21 years of age may
     participate. The Company's matching contribution is determined annually by
     the Board of Directors. Participants may make salary deferral contributions
     of 1% to 15% of their compensation not to exceed the maximum allowed by
     law. The expense for the year ended December 31, 1999, the period from
     April 1, 1998 (date operations commenced) to December 31, 1998, the period
     from January 1, 1998 to May 31, 1998 and the year ended December 31, 1997
     was $350,000, $103,000, $29,000 and $126,000, respectively.

14.  SHAREHOLDERS' EQUITY

     STOCK SPLITS

     In August 1999, the Company declared a 3-for-2 stock split by way of a
     stock dividend, which was paid on September 2, 1999. In January 2000, the
     Company declared a 3-for-2 stock split by way of a stock dividend, which
     was paid on February 2, 2000. The consolidated financial statements and the
     notes thereto give retroactive effect to the stock splits.

     SHAREHOLDER RIGHTS PLAN

     The Rights Agreement provides that .44 of a Right will be issued with each
     share of common stock issued on or after the date of distribution. The
     Rights become exercisable upon the occurrence of certain potential takeover
     events and will expire in December 2010 unless previously redeemed by the
     Company. When exercisable, each Right entitles the owner to purchase from
     the Company 1/100 of a share of Series A Junior Participating Preferred
     Stock ("Series A Preferred Stock") at a purchase price of $100.

     The Series A Preferred Stock will be entitled to a minimum preferential
     quarterly dividend payment of $.01 per share and will be entitled to an
     aggregate dividend of 225 times the dividend, if any, declared per share of
     common stock. In the event of liquidation, the holders of Series A
     Preferred Stock will be entitled to a minimum preferential liquidation
     payment of $100 per share and will be entitled to an aggregate payment of
     225 times the payment made per share of the common stock. Each share of
     Series A Preferred Stock will have 225 votes and will vote together with
     the common stock. In the event of any merger, consolidation or other
     transaction in which shares of common stock are changed or exchanged, each
     share of Series A Preferred Stock will be entitled to receive 225 times the
     amount received per share of common stock. The rights are protected by
     customary antidilution provisions.

     The 1,000,000 authorized shares of Series Preferred Stock are designated
     Series A Preferred Stock. No shares of Series A Preferred Stock are issued
     or outstanding.

     WARRANTS

     The Company had the following warrants outstanding as of December 31, 1999:
     (1) warrants to purchase an aggregate of 29,000 shares of common stock at
     $13.75 per share issued in 1999 that expire in August 2008, (2) warrants to
     purchase an aggregate of 225,000 shares of common stock at $22.22 per share
     issued in 1999 that expire in May 2004 and (3) warrants to purchase an
     aggregate of 563,000 shares of common stock at $13.33 per share issued in
     1999 that expire in May 2002. None of these warrants were exercised in
     1999.

     DISTRIBUTION WARRANTS AND STOCK OPTIONS

     In connection with the distribution of the Company to CCPR's shareholders,
     the Company issued warrants to purchase shares of common stock to holders
     of CCPR stock options who elected to receive warrants as follows: (1)
     warrants to purchase an aggregate of 4,303,000 shares of common stock at an
     exercise price of $5.86 per share which expire in 2005, (2) warrants to
     purchase an aggregate of 8,000 shares of common stock at an exercise price
     of $5.86 per share which expire in 2003 and (3) warrants to purchase an
     aggregate of 1,842,000 shares of common stock at an exercise price of $7.03
     which expire in 2005. As of December 31, 1999, warrants to purchase an
     aggregate of 47,000 shares of common stock at an exercise price of $5.86
     per share which expire in 2005 remain outstanding.

     There are 13,500,000 shares of common stock authorized for issuance under
     the 1998 CoreCom Limited Stock Option Plan and 5,625,000 shares of common
     stock authorized for issuance under the 1999 CoreCom Limited Stock Option
     Plan (together the "Plans"). The Plans provide that incentive stock
     options be granted at the fair market value of the Company's common stock
     on the date of grant, and nonqualified stock options be granted at a price
     determined by the Compensation and Option Committee. Options are generally
     exercisable as to 20% of the shares subject thereto on the date of grant
     and become exercisable as to an additional 20% of the shares subject
     thereto on each January 1 thereafter, while the optionee remains an
     employee of the Company. Options generally expire ten years after the date
     of the grant.

     In connection with the distribution of the Company to CCPR's shareholders,
     the Company issued approximately 1,877,000 options to purchase shares of
     the Company's common stock to holders of CCPR stock options who elected to
     receive options.

     Pro forma information regarding net loss and net loss per share is required
     by SFAS No. 123, and has been determined as if the Company had accounted
     for its employee warrants and stock options under the fair value method of
     that Statement. The fair value for these warrants and options was estimated
     at the date of grant using the Black-Scholes option pricing model with the
     following weighted-average assumptions for 1999 and 1998: risk-free
     interest rate of 6.81% and 5.02%, respectively, dividend yield of 0%,
     volatility factor of the expected market price of the Company's common
     stock of .465 and .810, respectively, and a weighted-average expected life
     of the warrants and options of 10 years.

     The Black-Scholes option valuation model was developed for use in
     estimating the fair value of traded options which have no vesting
     restrictions and are fully transferable. In addition, option valuation
     models require the input of highly subjective assumptions including the
     expected stock price volatility. Because the Company's distribution
     warrants and stock options have characteristics significantly different
     from those of traded options and because changes in the subjective input
     assumptions can materially affect the fair value estimate, in management's
     opinion, the existing models do not necessarily provide a reliable single
     measure of the fair value of its distribution warrants and stock options.

     At December 31, 1999, the Company had net operating loss carryforwards of
     approximately $88,000,000 for federal income tax purposes that begin to
     expire in 2018. The Company became eligible to file a consolidated federal
     income tax return in July 1999. Losses incurred prior to July 1999 may only
     be utilized by the subsidiary that generated the loss. The deferred tax
     assets have been fully offset by a valuation allowance due to the
     uncertainty of realizing such tax benefit.

16.  COMMITMENTS AND CONTINGENT LIABILITIES

     As of December 31, 1999, the Company had purchase commitments of
     approximately $41,000,000 outstanding.

     The Company is involved in various disputes, arising in the ordinary course
     of its business, which may result in pending or threatened litigation. None
     of these matters are expected to have a material adverse effect on the
     Company's financial position, results of operations or cash flows.

17.  SUBSEQUENT EVENTS (UNAUDITED)

     On March 10, 2000, the Company announced that it had entered into a
     definitive agreement to acquire ATX Telecommunications Services, Inc.
     ("ATX"), which is a facilities based CLEC and integrated communications
     provider serving the Mid-Atlantic states. The Company will pay  total
     consideration consisting of (a) approximately 12.4 million shares of the
     Company's common stock, (b) $250 million of 3% convertible preferred stock
     and (c) $150 million in cash, of which up to $70 million, at the Company's
     option, may be paid in senior notes with a two-year maturity. The
     convertible preferred stock will be convertible into common stock at $44.36
     per share. Under the agreement's cap provisions, the shares of common stock
     to be issued will be reduced if the Company's stock price at closing
     exceeds $46.38 per share, and the number of common shares underlying the
     convertible preferred stock will be reduced if the Company's stock price at
     closing exceeds $44.36 per share. The transaction is subject to regulatory
     and shareholder approval and other customary closing conditions.

17.  SUBSEQUENT EVENTS (UNAUDITED) (CONTINUED)

     On March 13, 2000, the Company and Voyager.net, Inc. ("Voyager.net")
     announced a definitive agreement to merge in a stock and cash transaction.
     Voyager.net is the largest full-service Internet communications company in
     the Midwest, and is rapidly expanding into DSL delivery of its services.
     Under the agreement, Voyager.net shareholders will receive 0.292 shares of
     the Company's common stock and $3 in cash for each share of Voyager.net
     common stock (an aggregate of approximately 9.2 million shares and
     approximately $95 million in cash). Under the agreement's collar
     provisions, the shares of common stock issued will be reduced if the
     Company's stock price at closing exceeds $57 per share, and increased if
     the Company's common stock price at closing is below $41 per share. If the
     Company's stock price at closing is below $33 per share, there would be no
     further adjustment to the number of shares of the Company's common stock
     issued and Voyager.net would have the right to terminate the transaction,
     subject to the Company's right to adjust further the shares issued. The
     transaction is subject to shareholder approval and other customary closing
     conditions. Holders of over a majority of the voting shares of Voyager.net
     have entered into an agreement with the Company to vote in favor of the
     transaction.

     In March 2000, the Compensation and Option Committee of the Board of
     Directors approved the issuance of options in the Company to various
     employees to acquire 2.7 million shares of the Company's common stock at an
     exercise price of 30% of the fair market value of the Company's common
     stock on the date of the grant. In accordance with APB Opinion No. 25,
     "Accounting for Stock Issued to Employees," the Company will record a
     non-cash compensation expense of approximately $44.8 million in March 2000
     and a non-cash deferred expense of approximately $48.5 million. The
     Company will charge the deferred expense to non-cash compensation expense
     on a straight-line basis over the vesting period of the stock options as
     follows: $15 million in 2000, $20 million in 2001, $11.6 million in 2002,
     $1.8 million in 2003 and $0.1 million in 2004.
